China takes a major key step toward building space-based solar power station
By Jia Fengfeng, People’s Daily
China has achieved a significant breakthrough in wireless power transmission, bringing the long-term vision of a space-based solar power station (SSPS) closer to reality.
Researchers at Xidian University in northwest China’s Shaanxi province have successfully demonstrated the world’s first ground verification system capable of transmitting microwave power wirelessly from a single transmitter to multiple moving targets simultaneously.
This achievement addresses one of the most critical technical challenges facing future space-based solar power systems. In the future, a single orbital power station could supply electricity to multiple spacecraft — or even mobile ground equipment on the ground — at the same time.
The milestone was reached in early spring this year at Xidian University’s Chang’an Campus in Xi’an, capital of Shaanxi province.
At the test site, a 75-meter-tall steel tower rose above the experimental field, its transmitting antenna aimed at receivers more than 100 meters away.
“It’s on! It’s on! They’re charging!” shouted Li Xun, a professor at the university’s School of Electronic Engineering, as LEDs mounted on unmanned aerial vehicles gradually lit up in the air.
For the research team, the successful demonstration marked the culmination of years of work to overcome one of the most difficult obstacles in wireless energy transmission: delivering high-power, high-efficiency microwave energy over long distances to multiple moving targets with precise beam control.
The concept of SSPS was first proposed in 1968, when scientists suggested placing massive solar power facilities in Earth’s orbit. Unlike ground-based solar farms, orbital systems would collect solar energy continuously, unaffected by weather or the day-night cycle. The electricity generated would be converted into microwaves or laser beams and transmitted wirelessly to Earth, where it would be converted back into electricity.
If realized, such a system could provide an abundant, nearly carbon-free source of clean energy.
For decades, however, the vision remained largely theoretical due to formidable technical challenges.
Only in recent years have advances in high-efficiency energy conversion, wireless power transmission and the construction of ultra-large space structures brought the concept significantly closer to reality.
China began researching space-based solar power in 2006.
In 2014, a research team led by Duan Baoyan, professor from Xidian University and an academician of the Chinese Academy of Engineering, proposed the OMEGA-SSPS concept, an independently developed design with independent intellectual property rights. Four years later, on Dec. 23, 2018, the university officially launched the Zhuri project, a ground verification system for space-based solar power technologies.
After another four years of intensive research, the team completed the world’s first full-chain, system-wide ground verification for SSPS using the self-developed OMEGA-SSPS ground test verification system in 2022.
A “full-chain” system means that every stage of the process from solar energy collection and photovoltaic conversion to microwave transmission, wireless propagation, reception, and rectification back into electricity, was successfully demonstrated as an integrated system.
“The key performance indicators at that time included a transmission distance of 55 meters between the transmitting and receiving antennas, a transmission power of 2,081 watts, a beam collection efficiency of 87.3 percent, and an end-to-end DC-to-DC transmission efficiency of 15.05 percent,” said Duan Xuechao, deputy dean of the School of Electronic Engineering at Xidian University. Those results ranked among the world’s most advanced at the time.
But that achievement was only the beginning. Supplying electricity to a stationary receiver is comparable to stretching an invisible power cable between two fixed points. Once the receiving target moves, however, maintaining accurate beam alignment becomes vastly more difficult. Moving from powering stationary targets to moving ones became the team’s next major challenge.
By the end of May this year, after another four years of research, the team unveiled Zhuri project 2.0 — the world’s first ground verification system capable of wirelessly transmitting microwave power from a single transmitter to multiple moving targets.
This “one-to-many” capability allows a single transmitting system to direct its microwave beam with exceptional precision, supplying power almost simultaneously to several fast-moving targets.
Researchers explained that the technical difficulty is similar to using a single beam of light in complete darkness to repeatedly and accurately hit multiple moving targets.
After years of efforts, the team finally achieved this breakthrough. Tests conducted this summer showed that over distances exceeding 100 meters, the system achieved a DC-to-DC transmission efficiency of 20.8 percent and a beam collection efficiency of 88 percent.
At the same time, drone flight tests were also successful. A drone flying at 30 kilometers per hour, and 30 meters from the transmitter, continuously received 143 watts of electrical power. The demonstration suggested that small drones could one day remain airborne while being recharged wirelessly during flight, significantly extending their operating endurance.
Countries including the United States, Japan and the Republic of Korea are all pursuing space-based solar power technologies. So far, however, China is the only country to have successfully demonstrated both a full-chain system and wireless power transmission from one transmitter to multiple moving targets.
The successful ground demonstration marks only the first step. According to China’s roadmap for space-based solar power development, the country aims to build a megawatt-class experimental power station in orbit by 2030, followed by a gigawatt-class commercial space-based solar power station by 2050.
Duan Baoyan outlined the enormous long-term potential of the technology. “If space-based solar power stations were deployed every 0.1 degree along geostationary orbit — roughly every 73

Hermann Simon: China fuels global growth for “hidden champions”
By Liu Zhonghua, People’s Daily
German management scholar Hermann Simon coined the term “hidden champions” to describe small and medium-sized enterprises (SMEs) that operate below the public radar yet dominate their niche markets — typically ranking among the top three globally in their sector. These firms are distinguished by deep specialization, relentless innovation, and a fundamentally global mindset.
Having visited China over 70 times and closely tracked its industrial evolution, Simon remains deeply optimistic about the vitality of its SME sector. In an exclusive interview with People’s Daily in Hasborn, Germany, he noted that China has systematically cultivated a new generation of “hidden champions” through a phased support framework tailored to different stages of enterprise development.
He spoke highly of China’s achievements in technological innovation, industrial upgrading, and through a phased support framework tailored to different stages of enterprise development. He emphasized that Chinese companies have already emerged as global innovators across several cutting-edge industries.
“The outdated notion that China merely replicates foreign technology no longer holds,” he said. “Chinese enterprises are now leading the way in innovation within multiple advanced fields.”
According to Simon, China’s approach centers on long-term strategic commitment. “The country guides its specialized firms to focus on foundational technologies and pursue continuous, incremental innovation. This disciplined approach is essential for overcoming core technological bottlenecks and securing dominant positions in global niche markets.”
He highlighted China’s five-year plans as a key driver of industrial clarity and strategic foresight. “Well-calibrated assessments of emerging sectors provide businesses with clear developmental pathways, showcasing strong institutional coordination,” Simon explained.
Strategic top-down planning, he added, helps consolidate resources, foster fair competition, and nurture globally competitive leaders. Strategic top-down planning, he added, helps consolidate resources, foster fair competition, and nurture globally competitive leaders. For other developing nations seeking to industrialize, he suggested studying China’s long-term strategy: leveraging domestic strengths to target distinctive niche industries and cultivate high-value-added champion enterprises offers a practical, scalable model.
Beyond macroeconomic growth, Simon underscored the role of these specialized firms in advancing balanced regional development and shared prosperity.
While large corporations typically concentrate in megacities, many “hidden champions” are rooted in counties, smaller cities, and townships.
He pointed to Shandong Moris Tech, based in Shouguang, east China’s Shandong province, which expanded its specialty chemical operations across regions while remaining rooted locally. “Nurturing these highly specialized enterprises distributes high-skilled jobs and value creation across broader urban and rural areas,” Simon observed.
“This provides a viable pathway toward more equitable regional development and inclusive prosperity.” Simon also pointed to China’s unparalleled industrial ecosystem as a major competitive advantage. With over 2,000 German firms operating manufacturing facilities in the country, he noted that dense supply chains and clustered industrial parks remain powerful draws.
“Comprehensive infrastructure, a vast talent pool of engineers, and a massive domestic market make China an ideal testing ground for advanced manufacturing technologies and their large-scale deployment,” he said. “Ignoring the Chinese market would mean forfeiting access to one of the world’s largest industrial hubs, which accounts for nearly one-fifth of global industrial output.”
He added that China’s resilient domestic demand offers multinational companies valuable medium- to long-term certainty.
Consequently, many German “hidden champions” have established R&D centers and integrated value chains in China, leveraging the country’s open, dynamic ecosystem to extend their corporate lifecycles.
China’s well-developed and open market is not only a growth engine for “hidden champions” worldwide, but also an important source of their core competitiveness, Simon said.
As competition intensifies across niche industries worldwide, greater coordination and collaboration among specialized companies in Europe and China could become an important force in reshaping the global industrial landscape, Simon said.
Two-way investment between Europe and China can help improve structural imbalances in trade and economic ties. As Chinese companies accelerate their localization efforts in Europe by establishing R&D and production bases and creating local tax revenue and jobs, economic and trade cooperation between China and Europe can evolve from one-way trade in goods toward joint industrial development, helping mitigate the risks posed by trade barriers.
Regular in-person exchanges can also strengthen business trust, stabilize expectations for industrial investment and help reduce misperceptions arising from geopolitical competition, Simon said.
Reflecting on the past two decades, Simon acknowledged that China’s manufacturing sector has undergone profound transformation. Many specialized enterprises have significantly upgraded their technological capabilities and product quality, successfully surmounting key innovation challenges.
Looking forward, he cautioned that Chinese companies still face hurdles in three areas: deepening their international footprint, building globally recognized brands, and executing localized overseas investments.
“I hope more Chinese manufacturers will expand into European and U.S. markets, achieving tangible progress in brand globalization; promote balanced and mutually beneficial industrial investment between China and Europe; and help preserve a stable, predictable global trade environment while safeguarding supply chain continuity,” Simon said.
“By deepening cooperation between Chinese and foreign real-economy sectors on the basis of openness, connectivity, mutual benefit and win-win outcomes, we can help safeguard the long-term stability and development of global industrial and supply chains,” he concluded.

A Decade of Growth: China-Europe Freight Rail Trips Surge 10.8-Fold
By Li Xinping, People’s Daily
This year marks the 10th anniversary of the China-Europe Railway Express operating under a unified brand. Over the past decade, the service has completed more than 130,000 journeys, transporting cargo valued at over $520 billion. What began as a regional freight initiative has evolved into a globally recognized logistics network.
Why has the China-Europe Railway Express developed so rapidly? Its unified brand has been crucial.
When the inaugural China-Europe freight train departed Chongqing in 2011, followed by subsequent services from Wuhan, Hunan, and Zhengzhou, growth was steady but fragmented. Annual departures rose from 80 in 2013 to 815 in 2015.
However, independently operated local services led to duplicated efforts, elevated costs, inconsistent standards, and weak market recognition — bottlenecks that threatened further scaling.
On June 8, 2016, the China-Europe Railway Express officially launched its unified brand. Featuring a streamlined emblem that combines railway and silk motifs in red and black, the new identity standardized train naming, visual design, and marketing across all participating regions.
By consolidating resources and aligning operational protocols, the network significantly strengthened its overall competitiveness. Annual train journeys jumped from 1,702 in 2016 to 20,022 in 2025 — a 10.8-fold increase, reflecting an average annual growth rate of 31.5 percent.
Today, the China-Europe Railway Express is increasingly recognized by countries along its routes for its advantages of speed, punctuality, safety, reliability, and environmental sustainability.
Connectivity remains the foundation of modern logistics. With unified branding and planning, service now operates three primary corridors — western, central, and eastern — spanning 96 scheduled routes at an average speed of 120 km/h.
At present, 129 Chinese cities connect to 236 cities in 26 European countries. Compared to 2016, the network has expanded by 113 cities domestically and 216 internationally, effectively covering much of the Eurasian landmass and providing a reliable backbone for cross-border trade.
Efficiency drives competitiveness. Transit speeds have been consistently optimized: trains cover approximately 1,600 km daily on Chinese territory and 1,000-1,300 km overseas, making them roughly one-third faster than conventional rail-sea intermodal alternatives.
Capacity has also scaled up; upgraded rolling stock now supports trains of up to 55 cars and a maximum trailing weight of 3,000 tons, enabling heavier loads without compromising speed.
Customs clearance has also become more efficient. In recent years, with the adoption of a “railway express” customs clearance model and the development of digital ports, customs clearance at China-Europe freight train ports has been reduced to as little as 30 minutes.
To simplify the supply chains, the service offers a centralized digital portal for end-to-end logistics management. For example, a Hangzhou-based equipment manufacturer executive recently used the platform to coordinate door-to-door transport, customs declaration, and integrated logistics. His shipment, dispatched from Zhengzhou, reached central Europe in just 17 days. Upon arrival, customer service teams remotely guided overseas partners through unloading to ensure a secure and efficient handover.
The model’s flexibility proved critical during a recent urgent shipment handled by a Xi’an-based logistics operator. A European chemical manufacturer needed 310 containers (18,600 tons) of raw materials delivered within 35 days. Ocean freight would take 45 to 60 days, while trucking would require over 600 vehicles and expose costs to volatile fuel prices.
“The China-Europe Railway Express took just 10 to 20 days for the full journey and had a large carrying capacity. It reduced total logistics costs by 29 percent, ensuring that the overseas chemical enterprise could start production on schedule,” said Su Lu, general manager of the Xi’an company.
As operations matured, transportation costs along both domestic and international segments have dropped by more than 40 percent since launch. Cargo diversity has expanded dramatically: trains now carry goods across 53 categories, covering more than 50,000 types of products. High-value-added goods, including automobiles and auto parts, machinery equipment, and electronics dominate outbound shipments, while inbound cargo includes timber, pulp, specialty agricultural products, and consumer goods.
Today, the China-Europe Railway Express continues to evolve.
On June 24, the first “zero-carbon” China-Europe freight train from the Yangtze River Delta successfully arrived at Yiwu West Railway Station in Zhejiang province. Operating under the Duisburg-Yiwu full-route timetable, the train used 100 percent green electricity on electrified sections. On non-electrified sections, it offset its remaining emissions through Gold Standard certified carbon offset projects, achieving net-zero carbon dioxide emissions during train operations.
As electrification upgrades continue along railway routes and clean transport vehicles, including new-energy heavy trucks, are increasingly deployed for cargo collection and distribution, the “steel camel caravan” spanning Eurasia is taking on an increasingly distinct green character.
After a decade of development, the “steel camel caravan” has grown far beyond a single transport route. With reliable capacity, efficient coordination and a commitment to green development, it has become a widely welcomed international public good.

Baton of China-U.S. friendship passed down from one generation to the next
By He Yin, People’s Daily
Veteran participants of China-U.S. “ping-pong diplomacy,” now well over seventy years of age, have returned to China, passing on to a younger generation the torch of friendship lit by the “little ball” that helped set the “big ball” of China-U.S. relations in motion.
Today, that tradition continues on the pickleball courts, where young Chinese and American players are forging new bonds. Embodying the ethos of “sportsmanship before victory,” they are proving that shared passion can transcend borders.
From table tennis, which helped open the door to China-U.S. exchanges 55 years ago, to pickleball, now increasingly popular among young people in both countries, this passing of the “little ball” from one generation to the next over more than half a century vividly demonstrates the enduring vitality of people-to-people exchanges between China and the United States and the deep, lasting friendship between the two peoples.
This year marks the 55th anniversary of China-U.S. “ping-pong diplomacy.” In 1971, a modest table tennis match shattered years of diplomatic isolation, reopening channels of communication and laying the groundwork for normalized relations. The event remains a landmark moment in modern diplomatic history.
Over the decades, numerous initiatives have deepened mutual understanding. Pioneering cultural missions, including performances by the Philadelphia Orchestra, helped lay the foundation for sustained artistic exchange. Meanwhile, the historic Kuliang friendship keeps alive a people-to-people friendship spanning a century. Together, these efforts have woven a rich tapestry of shared experiences.
In the new era, the spirit of engagement embodied in “ping-pong diplomacy,” which brought the Chinese and American peoples closer together, is taking on new forms and gaining new vitality.
Games like pickleball, known for their accessibility and social nature, effortlessly bridge linguistic, cultural, and geographical divides. For young Chinese and American athletes meeting for the first time, the court becomes a space for mutual learning, teamwork, and genuine connection.
These interactions reaffirm a fundamental truth: sustained people-to-people ties remain the bedrock of resilient China-U.S. relations, providing the trust necessary to navigate challenges and steer bilateral engagement forward.
Strong interpersonal connections are essential to stable diplomatic relations. Looking to the long-term development of friendship between the Chinese and American peoples, in San Francisco in 2023, Chinese President Xi Jinping proposed an initiative to invite 50,000 young Americans to China for exchange and study programs in a five-year span.
In just over two years, the number of young Americans who have visited China for exchanges has surpassed 50,000, achieving the target ahead of schedule. Driven by the initiative, a growing wave of American youth are traveling to China to explore its landscapes, engage with emerging technologies, and experience daily life firsthand.
By witnessing China’s developments directly, these visitors are moving beyond media narratives and algorithmic echo chambers, replacing stereotypes with nuanced, personal insights about mutual potential as partners and friends.
Many returnees have taken to social media to share their journeys, offering unfiltered perspectives to audiences back home. Their posts highlight how China’s rich heritage coexists with rapid innovation, while emphasizing the warmth, hospitality, and openness of its people.
As young Chinese and American travelers continue to bridging vast distances, they are planting seeds of mutual respect and shared curiosity. With time and cultivation, these connections will take root, fostering a more resilient, pragmatic, and constructive future for China-U.S.relations.
Today, China-U.S. relations once again stand at a critical juncture in history, and the strategic choices made by the two countries will once again shape the course of the world.
By making friends and competing within the rules on the pickleball court, young people from China and the United States are offering valuable lessons for the two countries on how to interact with each other.
Just as players on the court must follow the rules, China and the United States must coexist peacefully on this planet and refrain from crossing red lines or overstepping boundaries on issues concerning each other’s core interests.
And just as athletes improve through learning from and competing with one another, China and the United States should explore ways to expand areas of cooperation and do more things that benefit both countries and the wider world.
In recent years, young people from China and the United States have worked side by side aboard research vessels to unlock the mysteries of the ocean and joined forces at maker competitions to explore solutions to global challenges, demonstrating through action the enormous potential for cooperation between the two countries.
Looking ahead, the steady and sustained development of the “big ball” of China-U.S. relations will continue to depend on countless “little balls” of people-to-people friendship. People from all sectors of both countries, especially the younger generation, should draw wisdom and strength from history, get to know and grow closer to each other through exchanges and cooperation, and move forward together by learning from one another. By strengthening the bonds of friendship, they can make new contributions to stable, healthy and sustainable China-U.S. relations.
A small ball can connect people across mountains and seas; a bond of friendship can transcend time and space.
Just as pickleball draws on the strengths of several sports, the vast planet we share has ample room for China and the United States to pursue their respective development and achieve common prosperity, and for different civilizations to complement and enrich one another.
China remains committed to expanding people-to-people and cultural exchanges with the United States, writing a new chapter of friendship between the two peoples, and injecting a steady stream of people-to-people strength into building a constructive China-U.S. relationship of strategic stability.
