China’s New Battery and Hydrogen Technologies Are Powering the Future of the Low-Altitude Economy

For years, limited flight endurance has been one of the biggest obstacles to the widespread adoption of drones. Whether used for power line inspections, wildfire monitoring, emergency response, logistics, or low-altitude transportation, drones have been constrained by short flight times and slow energy replenishment. 

In May, however, two major technological breakthroughs from China offered new hope for overcoming this long-standing challenge. On May 6, the prestigious scientific journal Nature published a research paper by Professor Zhou Guangmin’s team from Tsinghua Shenzhen International Graduate School. The team introduced an innovative concept known as a “premediator,” a molecular design strategy that significantly improved the performance of lithium-sulfur batteries. Their prototype pouch cell achieved an energy density of 549 Wh/kg, nearly twice that of today’s mainstream commercial lithium-ion batteries.

Just four days later, another milestone was announced. Researchers at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, led by Academician Chen Zhongwei and Associate Professor Zhang Meng, unveiled a high-specific-power air-cooled hydrogen fuel cell stack. The technology passed a national scientific evaluation with a specific power of 1,970 W/kg, placing it among the world’s leading fuel cell systems.

Although these two innovations follow different technological paths, they share the same objective: enabling drones to fly farther, operate longer, and support the rapid growth of the low-altitude economy.

For drones, the greatest limitation has never been the electric motor, it has always been the power source. One of the most important indicators of battery performance is energy density, which measures how much energy can be stored per unit of weight. Higher energy density allows an aircraft to remain airborne longer without increasing its payload.

Today’s commercial lithium-ion batteries typically achieve practical energy densities between 250 and 300 Wh/kg. After decades of development, this technology is approaching its theoretical limits, making further improvements increasingly difficult.

As a result, researchers have turned their attention to lithium-sulfur batteries, which are widely regarded as one of the most promising next-generation energy storage technologies.

Sulfur is abundant, inexpensive, and environmentally friendly. In theory, lithium-sulfur batteries can store far more energy than conventional lithium-ion batteries. However, commercial development has been hindered by a major challenge known as the “shuttle effect.”

During battery discharge, sulfur is converted into intermediate compounds called polysulfides. These compounds tend to dissolve into the electrolyte and migrate between the battery’s electrodes, causing the gradual loss of active materials. As a result, battery capacity declines rapidly over repeated charging and discharging cycles.

Scientists around the world have spent more than a decade trying to suppress this phenomenon. Previous approaches focused on physically blocking the migration of polysulfides or chemically trapping them. While these methods achieved partial success, they often compromised energy density, battery weight, or long-term stability.

Professor Zhou’s team adopted a fundamentally different strategy.

Instead of attempting to block the polysulfides, they designed a special molecular structure called a premediator. This molecule remains chemically inactive during normal operation but is activated only when it encounters polysulfides inside the battery. Once activated, it performs two critical functions simultaneously: it confines the polysulfides near the cathode to reduce material loss while accelerating electrochemical reactions to improve energy conversion efficiency.

To identify the optimal molecular design, the researchers combined quantum chemical simulations with machine learning to screen nearly 200 candidate structures. The resulting battery maintained excellent cycling stability while achieving an energy density of 549 Wh/kg under practical testing conditions that closely resemble real-world applications.

The significance of this achievement extends beyond a new laboratory record. It represents an important step toward making lithium-sulfur batteries commercially viable for drones, electric vehicles, and future aerospace applications.

While lithium-sulfur batteries focus on storing more energy, hydrogen fuel cells offer another solution: supplying power continuously for much longer periods. The newly developed air-cooled fuel cell stack from the Dalian Institute of Chemical Physics delivers a specific power of 1,970 W/kg, meaning that every kilogram of the system can continuously produce nearly two kilowatts of power, approximately 60 percent higher than the performance of mainstream commercial air-cooled fuel cells.

Often described as the “heart” of a hydrogen-powered drone, the fuel cell stack generates electricity through the electrochemical reaction of hydrogen and oxygen. Unlike liquid-cooled systems, an air-cooled design dissipates heat using ambient air, eliminating pumps, coolant, and complex piping. This makes the system lighter, simpler, and particularly suitable for weight-sensitive platforms such as unmanned aerial vehicles.

Most industrial drones today can remain airborne for only 30 to 40 minutes before returning for battery replacement or recharging. Hydrogen-powered drones, by contrast, can operate for around two hours, while replacing a hydrogen cylinder takes only a few minutes instead of hours of charging. This dramatically improves operational efficiency for applications such as power grid inspection, pipeline monitoring, forest protection, and emergency rescue.

China has also made significant progress in hydrogen-powered aviation. 

The hydrogen-powered composite-wing drone Qing’ou-30B, developed by the Harbin Institute of Technology Chongqing Research Institute, has demonstrated flight endurance of up to 12 hours. Meanwhile, the AEP100 megawatt-class hydrogen turboprop engine has successfully completed flight testing, marking another important step toward large-scale hydrogen-powered aircraft.

Rather than competing with each other, lithium-sulfur batteries and hydrogen fuel cells are expected to serve complementary roles.

High-energy-density batteries are well suited for consumer drones, light industrial aircraft, and future electric vertical takeoff and landing (eVTOL) vehicles, where minimizing weight is essential. Hydrogen fuel cells, on the other hand, are better suited for long-endurance missions, heavy payload transportation, and continuous industrial operations requiring rapid refueling.

Together, these technologies are expanding the possibilities of the low-altitude economy. Of course, challenges remain before either technology can achieve widespread commercialization. Lithium-sulfur batteries must further improve manufacturing consistency, long-term durability, and safety. Hydrogen-powered systems still require broader hydrogen infrastructure, safer storage technologies, and lower life-cycle costs.

Nevertheless, the direction is becoming increasingly clear. As drone delivery, aerial inspection, urban air mobility, and advanced logistics continue to develop, energy systems will remain the foundation of future aviation. Breakthroughs in both lithium-sulfur batteries and hydrogen fuel cells demonstrate China’s growing capabilities in next-generation aerospace power technologies.

As these innovations move from research laboratories to commercial deployment, the long-standing endurance limitations of drones may finally become a challenge of the past, paving the way for a more efficient, sustainable, and connected low-altitude future.

China to Accelerate the Development of the Space Computing Industry Ecosystem

As artificial intelligence continues to advance at an unprecedented pace, global demand for computing power is growing exponentially. Traditional ground-based data centers are increasingly constrained by high energy consumption, limited land resources, cooling challenges, and geographical coverage limitations. 

Against this backdrop, deploying computing capabilities into space and building space-based computing networks has emerged as a new frontier in global technological competition. Companies in the United States, including those exploring AI-enabled satellites and space data centers, are accelerating their efforts to establish a foothold in this emerging sector.

China has already begun large-scale exploration in space computing. In May 2025, Chinese aerospace company Guoxing Aerospace, in collaboration with Zhejiang Lab, successfully launched the world’s first space computing satellite constellation from the Jiuquan Satellite Launch Center. 

The mission marked China’s transition from conceptual research to practical engineering implementation in space-based computing. The initial constellation consists of 12 computing satellites, with each satellite achieving a peak computing capability of 744 TOPS and the entire constellation reaching approximately 5 POPS of computing capacity. Equipped with an in-orbit artificial intelligence model, the system demonstrates the integration of “computing power in space, networked satellites, and AI models deployed in orbit.”

Space computing refers to the integration of computing, storage, and communication capabilities within orbital platforms. By combining satellite constellations, high-speed inter-satellite communication, and onboard intelligent processing systems, space computing enables real-time data processing, intelligent analysis, and autonomous decision-making directly in orbit.

One of the key drivers behind space computing is the growing difficulty of transmitting and processing massive volumes of satellite-generated data. As the number of satellites in orbit continues to increase, individual satellites can generate enormous amounts of data, while only a limited portion can be transmitted back to Earth due to communication bandwidth constraints, weather conditions, and transmission costs. 

By bringing computing capabilities into space, satellites can process and analyze data locally before sending critical information to the ground, transforming the traditional model from “collecting data in space and processing it on Earth” to “processing data directly in space.”

The rapid expansion of artificial intelligence has further intensified the demand for new computing infrastructure. Ground-based data centers require significant amounts of electricity and face increasing challenges in power supply, cooling efficiency, and physical space. In contrast, space offers abundant solar energy resources and vast deployment capacity, creating new opportunities for sustainable and globally distributed computing infrastructure.

China’s space computing industry has now moved beyond initial concept validation and entered a stage of technological demonstration and ecosystem development. Relying on independently developed intelligent satellite platforms, Chinese researchers have completed in-orbit verification of space computing systems and demonstrated the use of laser-based inter-satellite communication and distributed computing technologies to achieve efficient coordination among satellites.

Commercial applications are also beginning to emerge. In 2025, Guoxing Aerospace and industry partners conducted an in-orbit test involving a transportation AI model deployed on satellites. The system processed remote sensing images of the Pazhou area in Guangzhou, completing analysis and returning results within minutes while significantly reducing the need for ground-based data transmission. The project demonstrated the potential of space computing in practical scenarios such as intelligent transportation and remote sensing analysis.

At the policy and industrial level, China is accelerating efforts to cultivate a complete space computing ecosystem. Relevant authorities have initiated discussions on dedicated space intelligent computing constellations and are supporting research into key technologies, including radiation-resistant AI chips, high-speed laser communication, energy systems, thermal management, and computing standards. The development of space computing is expected to integrate multiple industries, including aerospace, telecommunications, semiconductor manufacturing, and artificial intelligence.

However, large-scale deployment of space computing still faces significant challenges. Space environments impose strict requirements on satellite reliability, radiation resistance, energy supply, and heat dissipation. High-performance computing hardware consumes substantial power and generates considerable heat, while satellites have limited space for cooling systems and energy generation. In addition, reducing launch costs remains a critical factor in achieving commercial scalability.

Industry experts believe that space computing must follow a gradual development path from experimental satellites to demonstration constellations and eventually large-scale networks. Instead of rapidly expanding physical infrastructure, the current priority should be breakthroughs in core technologies, industrial coordination, and standard development.

With continued advances in satellite manufacturing, commercial launch services, artificial intelligence hardware, and space communication technologies, space computing is expected to reach broader commercial adoption within the next five to ten years. As a strategic intersection of artificial intelligence, satellite internet, and aerospace technology, space computing could become a crucial component of future digital infrastructure.

China’s efforts to accelerate the development of the space computing ecosystem represent not only an attempt to overcome the limitations of traditional computing infrastructure but also a strategic move toward shaping the next generation of global computing networks.

Chinese Forensic Expert Zhang Mengting Solved a Criminal Case With a Drop of Mosquito Blood

Inside a spotless forensic laboratory in Xiangyang, central China’s Hubei Province, DNA analyst Zhang Mengting works in full protective gear, carefully transferring tiny amounts of liquid into test tubes with unwavering precision. Every movement demands absolute accuracy, because in forensic DNA analysis, even the smallest mistake can have profound consequences.

Since joining the Criminal Investigation Division of the Xiangyang Public Security Bureau in 2019, Zhang has examined more than 16,400 biological samples without a single recorded error. Over the past six years, she has helped identify suspects in more than 320 major and difficult criminal cases, located 35 missing or trafficked individuals, and reunited 42 separated families. In recognition of her contributions, she was awarded the Hubei May Day Labor Medal in 2025.

According to Zhang, DNA analysis is a profession that leaves no room for error. Any mistake could not only derail a criminal investigation but also permanently damage a forensic scientist’s professional credibility. She believes that meticulous attention to detail, patience, and scientific rigor are essential for uncovering the truth hidden within microscopic biological evidence.

One of her most remarkable investigations began in August 2020, when a serious criminal case occurred in Gucheng County, Xiangyang.

The crime scene yielded few useful clues, and investigators struggled to identify the suspects. Following the suspects’ escape route, police discovered a makeshift shelter in a remote rural area where they were believed to have spent the night. The shelter contained almost nothing of evidentiary value except an old bamboo sleeping mat.

While others saw little hope, Zhang carefully examined the mat centimeter by centimeter. Hidden inside a narrow seam, she discovered an extremely small bloodstain measuring only about two millimeters across. After closer inspection, she concluded that it was most likely the remains of a mosquito that had been crushed after feeding on human blood.

Because mosquitoes retain freshly ingested human blood for a period of time after feeding, the insect itself can preserve valuable human DNA. Zhang brought the mosquito remains back to the laboratory, where she and her colleagues spent more than 50 hours extracting and analyzing the tiny amount of genetic material mixed with the dried blood.

Their efforts succeeded. The recovered DNA profile matched records in the national database and directly identified the suspect.

Only nine days after the crime, police tracked down and arrested two fugitives in Jiujiang, Jiangxi Province. The case quickly attracted nationwide attention, with many Chinese internet users describing it as a real-life version of the forensic crime drama Forensic Heroes. The suspects had never imagined that a mosquito they casually swatted would ultimately become the key witness that led investigators directly to them.

For Zhang, however, the case simply illustrated a principle that guides all of her work. She believes that a single strand of hair, a drop of sweat, a tiny piece of skin, or any seemingly insignificant trace may become the key to revealing the truth. Physical evidence never presents itself voluntarily; only careful observation and painstaking examination can uncover the decisive clue hidden among countless insignificant details.

This philosophy has shaped many of her investigations. In 2024, a glass bottle thrown from a high-rise apartment building struck a parked car in Xiangcheng District of Xiangyang. The residential building contained more than 50 households, making a building-wide DNA collection impractical and extremely time-consuming.

Instead of requesting samples from every resident, Zhang extracted a male DNA profile from the shattered bottle and conducted further forensic analysis. By comparing the evidence with an existing local family DNA profile, she successfully narrowed the investigation and accurately identified the individual responsible for the high-altitude littering incident, saving investigators significant time and resources.

Beyond criminal investigations, Zhang has also used forensic genetics to reunite long-separated families. One particularly moving case involved a man surnamed Zhao, who had been abducted in 1974 at the age of three. His parents searched for him for decades without success. In 2017, his mother submitted a DNA sample to the national missing-person database, but because his father’s DNA was unavailable, investigators were unable to establish a complete genetic relationship.

In 2024, Zhang and her team adopted an innovative approach by analyzing DNA from Zhao’s biological brother to reconstruct the missing paternal genetic information. The reconstructed profile eventually led to a successful match, allowing Zhao to reunite with his family after nearly half a century apart.

By combining advanced forensic science with creative analytical methods, Zhang has helped return 35 missing or trafficked individuals to their families and brought closure to dozens of long-separated relatives.

The use of mosquito-derived DNA as forensic evidence was not unprecedented in China. In 2006, forensic expert Shen Gaofang helped solve the murder of a taxi driver in Yangzhou, Jiangsu Province, after investigators recovered a dead mosquito from a suspect’s residence. DNA extracted from the mosquito’s blood meal provided the crucial breakthrough that solved the case, and the investigation later became a classic teaching example within China’s criminal investigation system.

Similar cases have also appeared overseas. Finnish investigators once extracted human DNA from a blood-filled mosquito discovered inside a stolen vehicle and successfully identified a theft suspect through database comparison, demonstrating the growing capabilities of modern forensic science.

As DNA sequencing technologies become increasingly sensitive, even the smallest biological traces can provide decisive evidence. Hair, skin cells, sweat, blood, and even an ordinary mosquito may preserve the genetic information needed to solve a crime.

Working quietly behind laboratory doors, Zhang Mengting and countless other forensic scientists continue to transform silent traces into powerful evidence. Their meticulous work ensures that even the smallest fragment of biological material can help reveal the truth, bring criminals to justice, and reunite families separated for decades.

Chasing the Ripples of Space-Time: China Advances Toward the Frontiers of Gravitational Wave Detection

If electromagnetic waves allow humanity to see the universe, gravitational waves allow us to hear it. More than a century after Albert Einstein predicted their existence in his theory of general relativity, gravitational waves have opened an entirely new window onto the cosmos. 

Today, as nations compete to unlock the secrets of the universe, China is steadily emerging as a major player in the global race for space-based gravitational wave detection.

China recently marked another significant milestone in its ambitious Taiji Program, the country’s space-based gravitational wave detection initiative. Researchers at the Institute of Mechanics of the Chinese Academy of Sciences successfully developed the first fully functional interferometric optical platform designed specifically for the Taiji mission and completed rigorous ground testing. 

The achievement represents an important step from laboratory research toward engineering implementation, laying a solid technological foundation for China’s future gravitational wave observatory in space.

At the heart of the breakthrough lies one of the world’s most demanding measurement challenges. The research team introduced an innovative three-dimensional optical architecture that physically separates heat-generating components from the laser beam path, greatly reducing thermal interference. 

Combined with advanced noise-reduction algorithms developed by the team, the system achieves picometer-level precision, capable of detecting changes on the order of one ten-thousandth of the diameter of a human hair. Such extraordinary sensitivity satisfies the stringent requirements for future space-based laser ranging.

Often described as “ripples in space-time,” gravitational waves are generated whenever massive objects such as black holes or neutron stars accelerate or collide. Unlike light, they travel through the universe almost unaffected by dust, gas, or magnetic fields, carrying pristine information from the most violent events in cosmic history. For scientists, gravitational waves provide a completely new way to study the universe, offering insights into the formation of black holes, the evolution of galaxies, and even the earliest moments after the Big Bang.

In 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States announced the first direct detection of gravitational waves, capturing the signal produced by the merger of two black holes. The discovery confirmed Einstein’s century-old prediction and earned the 2017 Nobel Prize in Physics. However, ground-based detectors such as LIGO are sensitive mainly to high-frequency gravitational waves. Many of the most scientifically valuable signals, including those emitted by supermassive black holes and other large-scale astrophysical systems, exist at much lower frequencies and can only be observed from space.

Space-based gravitational wave observatories therefore represent the next frontier of gravitational-wave astronomy. Free from the seismic vibrations and environmental disturbances that limit ground observatories, satellites flying millions of kilometers apart can detect tiny changes in distance caused by passing gravitational waves. Such observations promise to reveal previously inaccessible phenomena and deepen humanity’s understanding of gravity, cosmic evolution, and the structure of the universe.

International competition in this field has become increasingly intense. The European Space Agency’s Laser Interferometer Space Antenna (LISA), scheduled for launch in the 2030s, will deploy three spacecraft separated by approximately five million kilometers to detect low-frequency gravitational waves. The United States has rejoined the project, making LISA one of the world’s most prominent international scientific collaborations.

China, meanwhile, has developed its own independent approach through the Taiji Program.

Proposed by the Chinese Academy of Sciences, the Taiji mission envisions three spacecraft orbiting the Sun in an equilateral triangle with arm lengths of approximately three million kilometers. Highly stable laser interferometers will continuously measure minute variations in the distances between the spacecraft, allowing scientists to detect gravitational waves passing through the constellation. 

The mission demands extraordinary technological capabilities, including ultra-stable laser interferometry, drag-free flight control, precision inertial sensors, micro-thrusters, and exceptionally stable spacecraft platforms.

To realize this vision, China has adopted a three-stage development strategy.

The first stage was successfully completed with the launch of Taiji-1 in 2019. As China’s first technology demonstration satellite for space-based gravitational wave detection, Taiji-1 verified several key technologies in orbit, including high-precision laser interferometry, inertial sensing, drag-free control, and micro-Newton propulsion. The mission confirmed the feasibility of China’s technical roadmap and provided valuable experience for subsequent missions.

The second stage will involve the launch of Taiji-2, a two-satellite mission designed to comprehensively validate critical technologies such as inter-satellite laser ranging and drag-free control while carrying out scientific experiments related to stochastic gravitational-wave backgrounds and relativistic frame-dragging effects.

The ultimate goal is Taiji-3, a three-satellite observatory with a baseline of three million kilometers that will conduct full-scale observations of low- and middle-frequency gravitational waves. If successful, it will enable China to explore some of the universe’s most energetic and distant phenomena while making significant contributions to global gravitational-wave astronomy.

China’s efforts extend beyond the Taiji Program. Another major initiative, the TianQin Project, led by Sun Yat-sen University, is pursuing a complementary space-based observatory in Earth orbit. The successful completion of the TianQin-1 technology demonstration mission has further strengthened China’s position in this rapidly advancing field.

In 2021, Chinese scientists published a comprehensive review in Nature Astronomy, introducing the concepts and progress of both the Taiji and TianQin projects to the international scientific community. Their research suggests that future joint observations involving Taiji, TianQin, and Europe’s LISA mission could dramatically improve the localization of gravitational-wave sources and enhance studies of black hole formation, cosmology, and the fundamental nature of gravity.

From the successful in-orbit verification of key technologies by Taiji-1 to the recent development of a fully functional interferometric optical platform, China’s space-based gravitational wave program has steadily progressed from theoretical concepts to engineering reality. Each technological advance brings the country closer to constructing a giant observatory spanning millions of kilometers in space, a scientific instrument capable of detecting the faintest vibrations of the universe.

The exploration of gravitational waves is ultimately a quest to answer some of humanity’s oldest questions: How did the universe begin? How do black holes evolve? What is the true nature of gravity? As China continues to advance the Taiji Program through sustained scientific innovation, it is not only pursuing national technological excellence but also contributing to one of humankind’s greatest endeavors, the exploration of the universe itself.

Chinese Researchers Use AI to Turn Wastewater Pollution into Fertilizer, Opening a New Path for Green Agriculture

Every year, hundreds of millions of tons of agricultural, industrial, and municipal wastewater carrying high concentrations of nitrate flow into rivers, lakes, and groundwater. These pollutants threaten drinking water supplies, fuel harmful algal blooms, and create oxygen-depleted “dead zones” that devastate aquatic ecosystems.

At the same time, producing the ammonia that underpins modern agriculture remains one of the world’s most energy-intensive industrial processes. More than 90% of global ammonia production still relies on the century-old Haber-Bosch process, which converts nitrogen from the air into ammonia under extremely high temperatures and pressures using natural gas or coal. According to the International Energy Agency (IEA), ammonia production accounts for roughly 2% of global final energy consumption and approximately 1.3% of energy-related carbon emissions.

One problem is environmental pollution. The other is the costly production of an essential industrial chemical. Yet both revolve around the same element nitrogen.

Now, a Chinese research team has demonstrated a promising way to connect these two challenges by directly converting nitrate pollutants in wastewater into ammonia, simultaneously treating contaminated water while producing a valuable chemical feedstock.

The breakthrough was achieved by a research team led by Han Lili at the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences. Their findings were published on March 18 in the Journal of the American Chemical Society (JACS) and were featured on the journal’s cover. The South China Morning Post later described the work as opening a new avenue for low-energy waste-to-resource technologies.

Unlike conventional single-atom catalysts, dual-atom catalysts consist of two neighboring metal atoms that work cooperatively throughout complex chemical reactions. Each atom can perform complementary functions, facilitating electron transfer, stabilizing reaction intermediates, and precisely controlling the breaking and formation of chemical bonds.

These characteristics make DACs particularly well suited for nitrate reduction, a reaction that involves multiple intermediate steps before ammonia is produced. 

However, designing an effective dual-atom catalyst has long been a major scientific challenge. Hundreds of possible metal combinations exist, and experimentally testing them one by one is both time-consuming and expensive.

To overcome this bottleneck, the Chinese researchers incorporated artificial intelligence into the catalyst design process.

Using a deep learning model, the team rapidly screened numerous metal combinations and predicted which pairs would most likely form stable structures with superior catalytic performance. Only the most promising candidates were then synthesized and experimentally validated, dramatically reducing the development cycle compared with conventional trial-and-error approaches.

Ultimately, the researchers successfully fabricated 14 precisely engineered dual-atom catalysts containing various rare-earth elements, including yttrium, scandium, lanthanum, cerium, samarium, europium, erbium, and ytterbium.

Even more remarkably, these catalysts achieved unprecedented metal loadings ranging from 12.8% to 30.7% by weight more than four times higher than previous benchmarks providing a significantly larger number of active catalytic sites.

The team then evaluated the catalysts in electrochemical nitrate reduction experiments using nitrate-rich wastewater. Credit to the abundance of highly active metal sites on the catalyst surface, ammonia production reached approximately 2.7 times that of conventional catalysts, approaching three times the efficiency of comparable systems while generating fewer unwanted byproducts.

In practical terms, this means that the same volume of wastewater can produce substantially more ammonia while simultaneously removing nitrate pollution more effectively. The reaction also proceeds under ambient conditions through electrochemical reduction, avoiding the extreme temperatures and pressures required by the Haber-Bosch process and potentially reducing overall energy consumption.

For decades, wastewater treatment and fertilizer production have operated as two completely separate industries. Conventional wastewater treatment focuses primarily on removing nitrate before discharging treated water. Although effective, this process consumes significant amounts of energy and operating costs while discarding nitrogen that could otherwise be reused.

Yet nitrate itself is simply another nitrogen-containing compound, and nitrogen is precisely the key ingredient required to produce ammonia, the foundation of virtually all nitrogen fertilizers.

If nitrate pollutants can be directly converted into ammonia, wastewater treatment would no longer be merely a pollution-control process. Instead, it would become a resource recovery system capable of generating economic value while protecting the environment.

This circular approach has the potential to reduce pollution, lower dependence on fossil-fuel-based ammonia production, and improve overall resource efficiency.

The technology could also have broader strategic implications. Global fertilizer markets have become increasingly vulnerable to fluctuations in energy prices and geopolitical tensions. Much of the world’s urea exports originate from the Middle East, where natural gas supplies and shipping routes through the Strait of Hormuz remain susceptible to regional instability.

Disruptions to natural gas supplies often translate directly into higher ammonia and fertilizer prices. Earlier this year, for example, India, the world’s second-largest importer of urea—was reportedly forced to purchase approximately 2.5 million tons of urea at nearly double the price paid just two months earlier.

China has largely maintained stable domestic fertilizer production through coal-based ammonia synthesis. Nevertheless, regardless of whether ammonia is produced from natural gas or coal, conventional synthesis remains highly energy-intensive.

Although recovering ammonia from wastewater is unlikely to replace large-scale fertilizer plants in the foreseeable future, it could become an important complementary source of nitrogen, improving the resilience and security of fertilizer supply during periods of energy market volatility.

Despite its promise, the technology is still at the laboratory stage. The reported experiments were conducted under controlled conditions on a relatively small scale. Real-world wastewater is considerably more complex, containing heavy metals, organic contaminants, suspended solids, and numerous other impurities that may reduce catalyst activity or shorten its operational lifetime.

In addition, several practical challenges remain unresolved, including large-scale catalyst manufacturing, integration with existing wastewater treatment infrastructure, long-term operational stability, and ensuring that the electricity required for electrochemical conversion comes from low-carbon energy sources.

Addressing these engineering and economic issues will be essential before the technology can be deployed commercially. Even so, the study demonstrates an important new direction for sustainable chemistry.

By combining artificial intelligence with advanced catalyst design, Chinese researchers have shown that wastewater pollutants can be transformed into valuable chemical resources rather than simply being removed and discarded.

If successfully scaled up, this waste-to-fertilizer approach could simultaneously reduce water pollution, lower the carbon footprint of fertilizer production, improve nitrogen recycling, and strengthen agricultural sustainability.

From Empire to Modern State: The Three-Century Transformation of China

0

The formation of the modern Chinese state was not simply a process of dynastic replacement or the collapse of an empire followed by the creation of a nation-state. Rather, it was a centuries-long process of state transformation involving territorial expansion, ethnic integration, fiscal and military restructuring, and the reconstruction of political identity. 

From the establishment of the Qing dynasty in the mid-seventeenth century to the founding of the People’s Republic of China in the mid-twentieth century, China experienced a profound transition: from a traditional ethnic-cultural state centered on the Han Chinese heartland, to a multiethnic territorial state, then to a modern sovereign state, and finally to a highly centralized modern political order. 

Understanding this transformation requires moving beyond the conventional “empire versus nation-state” framework and examining the interaction among three fundamental variables: geopolitics, fiscal-military structures, and political identity.

The development and transformation of states are fundamentally shaped by how they respond to external pressures, how they acquire and organize resources, and how they create shared political identities. 

Geopolitical conditions determine a state’s strategic priorities and security needs; fiscal-military institutions determine whether a state can convert social resources into political and military capacity; and political identity determines whether a state can effectively integrate different groups and sustain legitimacy. The evolution of modern China was the result of the continuous interaction among these three forces.

The Qing dynasty represented the crucial stage in which China transformed from a traditional ethnic-cultural state into a multiethnic territorial state. Before the Qing, successive Chinese dynasties were primarily based on a Han-centered political and cultural identity. 

Their political core was located south of the Great Wall, especially in the agricultural regions of the Central Plain, while the northern grasslands and frontier regions were often viewed as external spaces beyond the civilizational boundary. 

The rise of the Qing fundamentally changed this historical pattern. When the Manchus entered China proper and replaced the Ming dynasty, they not only established a new ruling dynasty but also redefined the meaning and geographical scope of “China.”

The Qing expansion occurred in two distinct stages. The first stage involved the rise of the Manchu state in the northeast, the conquest of the Ming dynasty, and the consolidation of control over the Chinese interior. In this period, Qing expansion resembled many other imperial formations: the primary objectives were the acquisition of territory, population, and economic resources. The second stage, however, was fundamentally different. From the late seventeenth century to the mid-eighteenth century, Qing campaigns against Mongolia, Xinjiang, and Tibet were not driven primarily by the pursuit of wealth or unlimited territorial expansion, but by strategic concerns related to security and geopolitical stability.

A central element of Qing geopolitical strategy was its alliance with Mongol groups beyond the Great Wall. This alliance had been essential to the Manchu conquest of the Ming and remained critical for protecting the capital and the northern frontier. When the Dzungar Mongols expanded eastward and threatened Qing interests, the Qing court launched a series of military campaigns. The incorporation of Outer Mongolia, Xinjiang, and Tibet into the Qing realm was therefore largely a consequence of defensive and preventive strategies rather than a deliberate attempt at imperial expansion.

This feature distinguished the Qing from many traditional empires. Unlike imperial powers that continuously expanded outward in search of resources, the Qing established relatively fixed borders after the mid-eighteenth century. It did not seek to exploit frontier regions as colonial possessions or major sources of taxation. Instead, the interior provinces served as the economic foundation of the state, while frontier regions functioned primarily as strategic buffers protecting the core territories. Through alliances, political recognition, religious patronage, and administrative control, the Qing maintained stability across a vast and diverse territory.

The Qing state also developed a distinctive fiscal-military structure. Unlike early modern European states, which were trapped in continuous military competition and therefore constantly expanded taxation and administrative capacity, the Qing faced relatively limited external military pressure for much of its history. As a result, it developed a low-tax, low-cost governing system. The state relied primarily on land taxation, while local social order was maintained to a considerable degree through gentry networks, clan organizations, and village institutions.

This system had significant advantages during periods of stability. The Qing government could maintain a large population and vast territory without creating an enormous bureaucratic apparatus or imposing heavy taxation. However, its weakness was its lack of flexibility. Because the fiscal system was designed for a relatively stable environment, it was poorly prepared for sudden geopolitical and domestic crises.

By the nineteenth century, this equilibrium began to collapse. Rapid population growth intensified pressure on land resources, contributing to large-scale internal conflicts. At the same time, European imperial powers entered East Asia and fundamentally altered China’s geopolitical environment. The Opium War and subsequent conflicts forced China into a global system of sovereign states dominated by Western powers, exposing the weaknesses of the traditional Qing order.

Yet the Qing state did not simply collapse. Instead, it underwent a significant transformation during the second half of the nineteenth century. One of the most important changes occurred in the fiscal and military sphere. The traditional land-tax-based fiscal system gradually evolved into a more flexible structure relying on customs revenue, commercial taxation, foreign loans, and other modern financial mechanisms. Although this transformation weakened central control over resources and strengthened regional officials, it also provided the financial foundation necessary for suppressing domestic rebellions, recovering Xinjiang, and launching modernization efforts.

The late Qing state developed a unique form of decentralized but still integrated governance. Regional governors gained greater control over taxation, military organization, and administration, but they remained connected to the central government through personnel appointments and political legitimacy. This system can be understood as a form of “localized centralism”: power and resources moved downward, but the overall national framework remained intact.

During this period, Chinese political identity also underwent a fundamental transformation. Centuries of Qing rule gradually created a shared sense of belonging among different ethnic communities, including Manchus, Han Chinese, Mongols, Tibetans, and Muslims. By the late nineteenth and early twentieth centuries, many Chinese intellectuals and officials began to move beyond loyalty to the dynasty itself and developed a broader identification with “China” as a territorial and political community. This transformation was crucial because it allowed the successor state after the fall of the Qing to inherit the Qing territorial framework rather than fragment along ethnic lines.

The twentieth century introduced a new stage in China’s state transformation. After the collapse of the Qing dynasty, central authority weakened and regional military leaders emerged, creating a period commonly described as warlord fragmentation. However, this era was not merely one of disorder. Within regional competition, new forms of state capacity emerged. Some regional regimes developed modern fiscal systems, administrative institutions, transportation networks, educational systems, and economic policies. In this sense, China’s reunification process resembled the experiences of later-forming European nation-states, where powerful regional forces first consolidated themselves before creating a unified national state.

The Nationalist Party (Kuomintang) eventually achieved formal unification through the Northern Expedition. Its success depended on three major factors. First, it received Soviet assistance, which strengthened its military organization. Second, it gained access to greater financial resources by consolidating Guangdong, expanding into the Yangtze River region, and later controlling national taxation systems. Third, it promoted nationalism and anti-imperialism, which helped it gain broader political support.

Before the outbreak of full-scale war with Japan, the Nationalist government had made significant progress in building a nationwide political and military structure. It gradually reduced regional fragmentation and began creating unified fiscal and administrative institutions. During the Second World War, this state structure enabled China to survive Japanese invasion and eventually emerge as one of the victorious Allied powers. China abolished unequal treaties imposed by foreign powers, recovered territories lost to Japan, and gained a permanent seat on the United Nations Security Council.

However, the same factors that explain the Nationalist Party’s achievements also explain its ultimate failure. Japanese aggression interrupted its state-building process. Financial pressures limited its governing capacity. Most importantly, the Nationalist government never achieved complete political and organizational centralization. Internal factions, regional military interests, and tensions between central and local authorities weakened its ability to coordinate national power effectively.

The Communist Party ultimately succeeded because it achieved a more comprehensive form of centralization in the areas of geopolitics, fiscal resources, and political identity. After the Second World War, Soviet involvement in Northeast China dramatically altered the balance of power. Northeast China possessed some of the country’s most developed industrial resources, transportation networks, and military infrastructure. By gaining access to this region, the Communist movement transformed itself from a relatively limited regional force into a powerful national military organization.

At the same time, the Communist Party developed a highly effective fiscal and mobilization system. It combined centralized control over economic resources with grassroots organization in rural society. Through land reform, party networks, and mass mobilization campaigns, it was able to obtain enormous human and material support. This combination of modern centralized institutions and deep social penetration created a sustainable source of military and political strength.

Most importantly, the Communist Party succeeded in creating a highly unified political organization. Through ideological discipline, party organization, and recognition of centralized leadership, it overcame regional divisions and internal conflicts. Compared with the Nationalists, the Communists achieved a much higher level of organizational cohesion. This enabled them to defeat their rivals and establish a new centralized state in 1949.

From a broader historical perspective, China’s modern state formation can be understood as a three-stage process. First, the Qing dynasty transformed China into a multiethnic territorial state. Second, the late Qing and Republican periods transformed this territorial state into a modern sovereign state recognized within the international system. Third, the revolutionary process of the twentieth century rebuilt political authority through centralization and party organization.

This historical trajectory differs fundamentally from the classic Western narrative of a transition from empire to nation-state. Modern China was not created by the collapse of an empire and the fragmentation of its territories into separate national units. Instead, it emerged through the accumulation of multiple historical layers. Traditional Chinese civilization provided the cultural foundation; Qing territorial expansion created the geographical framework of modern China; and twentieth-century political transformation created the centralized state structure that exists today.

Modern China therefore contains several historical dimensions simultaneously. It inherits the cultural traditions of the ancient Chinese civilization, the multiethnic territorial structure established by the Qing, the sovereignty recognized by the modern international system, and the centralized political organization developed during the twentieth century. Its formation was not the product of a single revolution or a single dynasty, but the result of centuries of historical transformation.

The “Chinese path” of state formation lies precisely in this unique combination of historical inheritances. The ancient Chinese state provided demographic and cultural foundations; the Qing created the territorial framework of a modern China; and the political transformations of the nineteenth and twentieth centuries shaped its institutional structure. Together, these forces produced a modern state that is vast in scale, territorially integrated, and politically centralized.

Nevertheless, state formation does not represent the end of state development. In the twenty-first century, China continues to face challenges involving regional integration, relations between the state and society, the construction of shared national identity, and its role within the global order. A mature modern state requires not only organizational strength but also broader social consensus and international responsibility. Understanding China’s historical transformation is therefore essential not only for explaining its past, but also for understanding its future.

Tarim Desert Highway Zero-Carbon Demonstration Project Surpasses 15 Million kWh of Green Electricity Generation

As of May 4, 2026, the Tarim Desert Highway Zero-Carbon Demonstration Project, developed by PetroChina Tarim Oilfield, has generated more than 15 million kilowatt-hours (kWh) of green electricity since it was commissioned. The project has replaced the consumption of more than 4,100 tonnes of diesel fuel, reduced approximately 14,200 tonnes of carbon dioxide emissions, and achieved an average daily power generation exceeding 11,000 kWh. This pioneering project has become a successful model for zero-carbon operation of desert highways while providing valuable experience for desertification control and low-carbon development in China.

In recent years, Xinjiang has accelerated the green transformation of its economy in line with China’s carbon peaking and carbon neutrality goals. As part of the region’s efforts to promote industrial green development, the oil and gas production and processing sector has actively explored the integration of traditional energy resources with renewable energy. 

The Tarim Desert Highway Zero-Carbon Demonstration Project represents one of the most significant achievements of this strategy, combining photovoltaic power generation with ecological restoration to realize coordinated economic, environmental, and social benefits.

The Taklimakan Desert, often referred to as the “Sea of Death,” covers approximately 330,000 square kilometers, making it the world’s second-largest shifting sand desert. Despite its harsh environment, it contains abundant oil and gas resources. 

To support exploration, development, and transportation activities, the Tarim Desert Highway, stretching 522 kilometers, was completed in 1995. It became the world’s longest graded highway crossing a shifting desert, significantly shortening travel distances between southern Xinjiang and Urumqi while providing vital transportation infrastructure for energy development.

Building the highway was only the beginning. Protecting it from relentless sand encroachment proved to be an even greater challenge. In 2003, construction began on the Tarim Desert Highway Ecological Shelterbelt Project. Completed in 2006, the project established a 436-kilometer-long ecological shelterbelt covering more than 3,100 hectares along both sides of the highway. More than 20 million drought- and salt-tolerant shrubs, including saxaul, tamarisk, and Calligonum, were planted. 

A network of 109 water wells, supplied by shallow, highly mineralized groundwater and operated through drip irrigation systems, was built to sustain the vegetation. After more than two decades of maintenance, this green corridor has become the world’s first ecological forest successfully established across a shifting desert, effectively controlling sand movement and ensuring the long-term safety of the highway.

Responding to China’s initiative to accelerate the development of large-scale renewable energy bases in deserts, the Gobi, and other arid regions, PetroChina Tarim Oilfield launched the Zero-Carbon Demonstration Project in 2022. Remarkably, the entire project was completed and commissioned in just over 140 days.

The project constructed 86 distributed photovoltaic power stations along the 436-kilometer shelterbelt, with a total installed capacity of 3.54 megawatts (MW). Solar power has completely replaced diesel generators that previously supplied electricity for pumping irrigation water to the shelterbelt. Before the upgrade, the remote desert location prevented access to the national power grid, making diesel generators the only available power source. 

This approach involved high fuel transportation costs, difficult equipment maintenance under extreme desert conditions, and significant carbon emissions. The photovoltaic system has eliminated these challenges while enabling the shelterbelt to operate entirely on clean energy.

Today, rows of solar panels stand beside the highway alongside white-and-red well houses and flourishing vegetation, creating a striking contrast against the vast desert landscape. The renewable energy system supplies all the electricity required for daily irrigation, allowing the shelterbelt to thrive entirely on solar power.

The photovoltaic facilities generate more than 3 million kWh of electricity annually, enough to meet the irrigation demand of the ecological shelterbelt. Each year, the system saves over 1,000 tonnes of diesel fuel and reduces carbon emissions by approximately 3,000 tonnes. Meanwhile, the shelterbelt itself absorbs an estimated 20,000 tonnes of carbon dioxide annually. This carbon sequestration not only offsets the project’s own emissions but also neutralizes emissions produced by nearly 90,000 vehicle trips along the highway each year, enabling the project to achieve net-negative carbon performance.

The cumulative generation of over 15 million kWh of green electricity demonstrates the project’s long-term effectiveness. It has become a benchmark for integrating renewable energy, ecological conservation, and transportation infrastructure in extreme environments.

To date, PetroChina Tarim Oilfield has also completed five large-scale ground-mounted photovoltaic power stations and 239 distributed solar projects across the Tarim Basin, with a total installed renewable energy capacity of 2.6 gigawatts (GW). The Desert Highway Zero-Carbon Demonstration Project was recognized as one of the “Top Ten Super Projects of Central State-owned Enterprises in 2022” by China’s State-owned Assets Supervision and Administration Commission.

From constructing the desert highway, to establishing the world’s first ecological shelterbelt across a shifting desert, and finally achieving zero-carbon irrigation powered entirely by solar energy, the Tarim Oilfield has pioneered an innovative model that integrates transportation infrastructure, ecological restoration, and renewable energy development. 

Today, travelers crossing the Taklimakan Desert encounter not only endless sand dunes but also thriving green corridors and rows of photovoltaic panels, an inspiring symbol of China’s commitment to sustainable development and ecological civilization. The Tarim Desert Highway Zero-Carbon Demonstration Project now serves as a replicable model for zero-carbon infrastructure and desertification control both in China and beyond.

China’s Pet Funeral Industry Reflects a Changing Relationship with Animals

0

In 2024, China’s pet population surpassed 120 million. As pets increasingly become emotional companions rather than simply household animals, a new question has gained attention among millions of owners: how should a pet’s life be respectfully concluded?

For many years, the death of a pet was rarely discussed. After an animal passed away, owners often had limited options beyond simple disposal or burial. Today, however, more and more people are choosing to give their pets a formal farewell. Services such as cremation, farewell ceremonies, ashes preservation, and memorial products are gradually becoming part of China’s expanding pet economy.

Behind this change is the rapid growth of a new market. By June 2025, more than 8,000 companies in China had registered business activities related to pet funeral services, with many established within the past three years. Industry reports estimate that China’s pet funeral market reached around 230 million euros in 2023 and could exceed 1.3 billion euros by 2030. The rise of this industry is closely linked to two major trends: the growing number of pets and the changing emotional role they play in people’s lives.

For many urban families, pets are no longer simply animals kept at home. They are companions that share daily routines, provide emotional support, and accompany people through important moments. A cat or dog may spend more than a decade with a family, becoming part of memories connected to relationships, work, relocation, and personal growth.

When such a companion dies, many owners are not only dealing with the loss of an animal, but also the disappearance of a familiar presence in their lives. This emotional demand has transformed pet funeral services from simple disposal into a form of farewell ceremony.

A typical process may include collecting the pet’s body, cleaning and arranging it, holding a private farewell ceremony, completing cremation, and preserving the ashes. Some owners choose to keep paw prints, fur samples, photographs, or customized memorial items as reminders of their pets.

Prices vary depending on location and services. In major cities such as Beijing, Shanghai, and Chongqing, pet funeral services have become increasingly visible. The industry, once concentrated mainly in first-tier cities, is now expanding into smaller urban areas as demand changes from simply asking “is there such a service?” to “is the service professional and respectful?”

Behind this market expansion are countless emotional stories. A pet funeral worker once recalled receiving a small dog that had died in a traffic accident. The animal’s injuries were severe, and its owners, a mother and daughter, were devastated when they arrived. Unable to provide professional reconstruction, the staff carefully cleaned the body and covered the injuries so that the family’s final memory would not be filled with painful images.

For many workers in this industry, the goal is simple: to allow an animal to leave with dignity.

Their work is not only about handling remains. It is also about supporting people at one of their most vulnerable moments.

Some owners arrive at funeral facilities overwhelmed and unsure what to do next. Others initially request the simplest possible service because they cannot accept the reality of the loss. But when cremation approaches, some suddenly ask to see their pets one more time.

Many workers have found that farewell ceremonies are not unnecessary rituals. Instead, they can help owners acknowledge the loss and begin the process of moving forward.

People respond differently to these moments. Younger owners may speak to their pets as if they were still alive, calling their names and recalling memories. Older owners often remain quiet, standing beside the farewell room and silently watching. Some people leave the room briefly because they cannot hold back their emotions.

The experience of working with death has also changed the perspectives of many pet funeral professionals themselves. One worker once said that after years in the industry, he rarely cried because the animals he handled had already passed away. He had never seen them running, playing, or interacting with their families, so it was difficult to form a personal connection.

That changed after he encountered a rescued stray cat. The cat was found injured on the roadside and appeared lifeless. As preparations were being made, it suddenly moved and let out a weak cry. It was rushed to a hospital and survived. The rescuers gave it a name that represented hope for a better future. A year later, the cat died because of illness.

Seeing the same animal that had once fought for life lying on the farewell table made the worker understand something he had previously struggled to fully grasp: people are not only mourning death itself. They are mourning the future they imagined but will never see.

However, as the industry grows, it also faces challenges.

Because pet funeral services are still relatively new in China, regulations and industry standards remain incomplete. Problems such as unlicensed operations, misleading advertising, unclear pricing, and excessive sales practices have appeared in some areas.

Some consumers have reported paying for “individual cremation” but being unable to verify whether the process was actually carried out separately. Others have said they were encouraged to purchase additional services at emotionally difficult moments.

The industry also faces regulatory complexity. Pet funeral services involve multiple areas, including animal disease prevention, environmental protection, and market supervision. In the past, many operators lacked clear guidance on what qualifications and procedures were required.

Location is another challenge. Because funeral services are traditionally associated with negative perceptions, some communities resist pet funeral facilities nearby. As a result, many businesses operate in suburban areas and maintain a low profile.

Yet these challenges also reflect an industry moving from rapid expansion toward greater regulation.

In recent years, Chinese authorities have paid increasing attention to the proper handling of animal remains. Regulations require deceased animals to undergo appropriate disposal procedures rather than being abandoned. Some regions have begun developing professional facilities that provide transportation, disease prevention, and standardized treatment services.

Meanwhile, responsible operators are improving transparency. Some record cremation procedures to reassure owners, while others participate in charity programs that provide free cremation services for stray animals.

The development of China’s pet funeral industry is ultimately about more than business.

It reflects a broader social change: a growing recognition that animals can hold emotional value and deserve respect at the end of their lives.

China’s relationship with pets is evolving. What was once a rarely discussed topic is becoming part of modern urban life. From a simple act of disposal to a meaningful farewell, pet funeral services represent a society that is gradually learning to value companionship, memory, and every form of life.

For many owners, the final farewell is not only about saying goodbye. It is about preserving the years of love and companionship that came before.

The Forgotten Front: Africa’s Contribution to the Second World War and the Legacy of Its Soldiers

0

The Second World War was the largest and deadliest conflict in human history. Every year, commemorations around the world honor the victims of the war and pay tribute to those who sacrificed their lives in the struggle against fascism. Yet amid these grand narratives, one immense group has remained largely absent from public memory: the African soldiers who fought alongside the Allied powers.

The United Nations General Assembly has designated 8 and 9 May as the Time of Remembrance and Reconciliation for Those Who Lost Their Lives during the Second World War, a reminder that the history of the war belongs not only to Europe but to all those who contributed to the defeat of fascism. 

During the conflict, approximately one million Africans were recruited into the Allied forces. They fought across Africa, the Middle East, Europe, and Asia, shedding blood on battlefields far from home. Their contribution to Allied victory was indispensable, yet after the war they received little recognition and were gradually erased from mainstream historical narratives.

For most African soldiers, participation in the war was not a matter of choice. Since much of Africa remained under British, French, Belgian, and other colonial rule, colonial administrations relied on compulsory recruitment, pressure from local chiefs, and, in many cases, outright coercion to fill their ranks. Although wartime propaganda often portrayed these men as volunteers, historical research has demonstrated that many had no real opportunity to refuse.

Historian David Killingray estimates that more than half a million Africans served in the British Army between 1939 and 1945, including nearly 290,000 soldiers of the King’s African Rifles. This represented the largest movement of African people across continents since the transatlantic slave trade. Under French colonial rule, the recruitment of African troops had begun much earlier. The famous Tirailleurs Sénégalais, established in 1857, recruited soldiers not only from present-day Senegal but from across French West and Central Africa. Many of the earliest recruits had themselves been enslaved before being incorporated into the French colonial army. These troops were employed to conquer colonial territories, suppress resistance movements, and later fight in both World Wars.

When the Second World War erupted, soldiers from territories that are now Nigeria, Ghana, Kenya, Uganda, Tanzania, and many other African countries were deployed to multiple theatres of war. Hundreds of thousands of West African troops were sent to the Burma Campaign, where they fought fiercely against the Imperial Japanese Army.

Among them was Joseph Ashitey Hammond, born in Ghana in 1925, who served with the British Royal West African Frontier Force in Burma. In his autobiography, he pointed out that he is one of the forgotten African soldiers, but their story deserves to be told. Even decades after the war, Hammond described the fighting as “terrifying” and “brutal,” admitting that he could scarcely believe he had survived to recount those experiences. Fighting in Burma also shaped his understanding of the conflict. He came to realize that Japan’s military expansion was driven by imperial conquest and that its militarist ambitions had brought devastation to countless nations across Asia.

Another veteran, Ebou Janha of The Gambia, spent two years fighting in Burma’s jungles and mountains. Recalling combat against Japanese forces, He recalled that when African troops encountered Japanese soldiers, they could hardly tell whether they were human or ghosts, as the Japanese wore camouflage and laid traps everywhere. Like countless other African soldiers, Janha endured the same dangers and hardships as his European comrades, yet his experiences remain largely absent from popular accounts of the war.

African soldiers also played significant roles in Europe, North Africa, and the Middle East. One of the most tragic examples occurred during the 1941 Syria-Lebanon Campaign. Both Vichy France and the Free French forces relied heavily on African colonial troops, meaning that soldiers from the same regions of West Africa were forced to fight one another in a conflict that had little to do with their own homeland. By the end of the campaign, many African troops on both sides refused to continue fighting, unwilling to kill fellow Africans in a colonial war.

The European theatre brought further suffering. After France fell in 1940, thousands of African soldiers were captured by Nazi Germany. Subjected to racist policies, many were forced into hard labor, imprisoned in segregated camps, or summarily executed. Among the prisoners was Léopold Sédar Senghor, who would later become the first president of independent Senegal. While imprisoned in German camps reserved for colonial troops, Senghor witnessed the systematic abuse and killing of African prisoners of war, an experience that profoundly influenced his later writings.

The discrimination African soldiers faced did not end with the battlefield. A 2019 investigation by Al Jazeera revealed that African soldiers serving in the British Army were paid only a fraction of what white soldiers earned and often endured conditions resembling forced labor. In the French Army, inequality was even more deeply entrenched. After the liberation of France in 1944, General Charles de Gaulle initiated a policy of “whitening” the French Army. Thousands of African soldiers who had fought on the front lines were disarmed, removed from combat, and sent home, while white French troops continued the advance into Germany.

Even worse, these veterans were denied the wages, pensions, and benefits they had been promised. In December 1944, African veterans held at the Thiaroye transit camp near Dakar protested over unpaid salaries. French colonial authorities responded by opening fire on the very men who had fought against Nazi Germany. Dozens were killed and hundreds wounded in what became known as the Thiaroye Massacre, a tragedy that remained largely absent from official French history for decades.

British colonial authorities acted in similar ways. In 1948, veterans in the Gold Coast (present-day Ghana) peacefully petitioned for unpaid pensions and compensation. Colonial police opened fire, killing several demonstrators. Men who had risked their lives for the Allied cause returned home only to find themselves once again victims of colonial oppression.

The inequalities extended into public memory. Across Kenya, Tanzania, and other former British colonies, Commonwealth cemeteries honoring British soldiers have been meticulously maintained, while countless African soldiers remain unnamed or buried without proper memorials. Annual commemorations in Europe regularly celebrate Allied veterans, yet African veterans have rarely been invited to participate, despite having fought and died alongside their European comrades.

At the same time, however, the war profoundly transformed Africa itself.

Military service exposed African soldiers to new technologies, technical training, organizational skills, and ideas about freedom and citizenship. For many, the experience broadened their horizons and challenged the legitimacy of colonial rule. On a psychological level, African soldiers gained confidence from defeating formidable enemies such as Imperial Japan. Politically, they returned convinced that the moment had come to demand independence.

Indeed, following the end of the war in 1945, nationalist movements spread rapidly across the continent. Kenya’s Mau Mau uprising, Ghana’s struggle for independence, and Algeria’s war of liberation all benefited from the participation of former soldiers who brought back military experience, leadership skills, and a new sense of political consciousness.

Colonial repression after the war only strengthened demands for independence. On 8 May 1945, while Europe celebrated victory over Nazi Germany, French colonial forces violently suppressed peaceful demonstrations in Sétif, Algeria. Tens of thousands of Algerians were killed during the ensuing massacres, shattering any remaining faith in French promises of liberty and equality. The events at Sétif became one of the defining moments that eventually led to Algeria’s struggle for independence.

More than eighty years later, historians increasingly recognize that the history of the Second World War cannot be understood solely through a European lens. From the jungles of Burma to the deserts of North Africa, from the mountains of Italy to the battlefields of France and the Middle East, African soldiers fought with extraordinary courage against fascism. Many died far from home; others survived only to face discrimination, poverty, and colonial violence. Still others became leaders of the movements that would eventually dismantle European empires across Africa.

Today, scholars, veterans’ organizations, and civil society groups throughout Africa continue to call for these forgotten soldiers to receive the recognition they deserve. They advocate for public memorials, oral history projects, proper maintenance of African war graves, and greater inclusion of Africa’s wartime experience in school curricula. 

These efforts seek not only to honor individual sacrifice but also to restore an essential chapter of global history.

China Safeguards AI Sovereignty: Why the Manus–Meta Deal Was Rightly Blocked

0

In March 2025, an AI agent product named Manus, also known in Chinese as Butterfly Effect, emerged as a major technological breakthrough. Developed by a China-based team, the system moved beyond traditional conversational AI by autonomously planning tasks, invoking tools, and delivering complete outputs. It was widely regarded as a milestone in the development of general-purpose AI agents. Within days of its release, the product attracted millions of users to its waiting list, invitation codes surged in secondary markets, and the company’s valuation climbed rapidly from under $100 million to around $500 million, making it one of the most prominent AI innovations in China at the time.

As the product gained traction, capital quickly followed. In April 2025, Manus secured investment from a U.S. venture capital firm. However, the deal soon drew scrutiny from U.S. regulators, as artificial intelligence had already been classified as a sensitive sector under tightening outbound investment restrictions. This external pressure, combined with the company’s ambition to expand globally, prompted a strategic shift.

Between June and July 2025, Manus undertook a major restructuring. The company relocated its headquarters to Singapore and established Butterfly Effect Pte. Ltd. as its new global operating entity. At the same time, its domestic team was significantly downsized, with core members relocating overseas, while its presence in China, both operationally and online, was gradually reduced. These moves effectively repositioned the company as an offshore entity in legal terms, aiming to separate its corporate identity from its origins.

Following the relocation, Manus continued to grow rapidly. By the end of 2025, it reported annualized revenue exceeding $100 million, alongside substantial increases in data processing volume and user activity. Against this backdrop, Meta initiated acquisition talks in December 2025 and moved quickly to finalize a deal valued at over $2 billion. The transaction was structured to avoid directly acquiring core assets or intellectual property, thereby attempting to minimize regulatory obstacles.

However, the regulatory environment shifted in early 2026. Chinese authorities began reviewing the deal, focusing on issues such as technology export, cross-border data flows, and changes in control. On April 27, 2026, China’s Office of the Working Mechanism for Foreign Investment Security Review formally prohibited the acquisition, requiring the parties to terminate the transaction and carry out follow-up compliance measures. This decision effectively ended the deal and marked a significant case in China’s scrutiny of foreign acquisitions in the AI sector.

From a regulatory perspective, the decision was not aimed at a single corporate action but reflected a broader set of considerations. First, the origin of the technology remained a decisive factor. Manus’s core algorithms and research capabilities were developed in China, and its technological foundation was built upon domestic engineering resources. Relocating the corporate entity abroad did not alter this underlying reality. Second, data governance emerged as a critical issue. As an AI agent platform, Manus processed vast amounts of user data, including a substantial portion originating from Chinese users, raising concerns over cross-border data transfers and compliance. Third, at a strategic level, general-purpose AI agents are increasingly viewed as potential infrastructure, making their ownership and control matters of national interest.

In this context, regulators adopted what can be described as a “capability-level” review approach. Rather than focusing solely on transaction structures or asset transfers, the assessment centered on whether critical technological capabilities, core teams, and strategic directions would effectively shift under foreign control. This helps explain why the case ultimately fell under the foreign investment security review framework, instead of being handled purely through technology export or data regulations.

The case also highlights the complex landscape facing technology companies pursuing global expansion. On one hand, governments around the world are strengthening controls over critical technologies, data resources, and high-skilled talent. On the other hand, companies still need access to international capital and markets to remain competitive. In such an environment, relying solely on corporate structuring to navigate regulatory systems is becoming increasingly ineffective.

For companies, the implications are clear. Globalization strategies must be grounded in comprehensive compliance frameworks. Key areas including corporate structuring, cross-border data management, technology transfer, and capital operations require thorough upfront assessment and ongoing oversight. Compliance is no longer a secondary consideration but a central capability that determines long-term viability.

More broadly, the case reflects the evolution of regulatory systems toward greater sophistication and earlier intervention. While innovation and international collaboration continue to be encouraged, higher expectations are being placed on safeguarding control over critical technologies and ensuring national security. Going forward, companies will need to navigate multiple regulatory regimes simultaneously and strike a balance between global ambition and legal constraints. Operating within established rules, rather than attempting to circumvent them, is likely to become the defining approach for technology firms expanding onto the global stage.
