In a farm in northwest China’s Gansu province, sensors are inserted into the soil to monitor humidity, while a miniature weather station tracks wind and light conditions.

“Last year, the sunflower yield per mu (about 667 square meters) exceeded 280 kilograms, an increase of 15 percent,” said Zou Changsheng, head of the project department of the farm.

With the use of smart irrigation, bountiful harvests were guaranteed, and the water usage per mu has decreased from 650 cubic meters to 300 cubic meters, Zou added.

The irrigation water comes from the Shule River, which flows through the desert, nurturing oasis along its path. The Shule River provides irrigation water for a total of 1.34 million mu of farmland spread across 22 townships in Jiuquan, Yumen, and Guazhou county, as well as six farms.

The Shule River basin receives less than 70 millimeters of precipitation annually, while the evaporation is as high as 2,800 millimeters. How can this water-deficient river achieve intensive water conservation while ensuring proper irrigation?

“We have ‘digitized’ the Shule River,” said Zhang Farong, deputy director of the planning department of the Shule River basin water resources utilization center in Gansu province.

By leveraging geographic information systems and building information modeling, a virtual model has been constructed to simulate the river channel, canal system, reservoirs, and water gates in equal proportion, creating a “digital twin” of the river, Zhang explained.

Through large model simulation, water resource scheduling plans have been continuously optimized. Manual gate operations have been automated, enabling precise water release based on demand. The construction of high-standard farmland is advancing in sync, with integrated water and fertilizer technologies such as drip irrigation and precision fertilization, saving both labor and water. By combining data, algorithms, and computing power, the Shule River irrigation area is gradually becoming a leading example of water conservation.

These efforts to use digital technology to promote water-saving agriculture in the Shule River basin reflect China’s rapid progress in developing a digital twin system for water resources management.

“In simple terms, digital twin water resources management refers to the use of technologies such as artificial intelligence, 5G, and large models to virtually replicate natural water systems and hydraulic engineering structures on the internet. This enables the simulation of interactions between physical and virtual objects, facilitating precise forecasting, early warnings, rapid scenario simulations, and the development of contingency plans,” said Sun Chunpeng, director of the hydrological information forecasting center at the Ministry of Water Resources.

In recent years, China’s water resources sector has completed 94 construction tasks of digital twin for water resourcemanagement .

The construction of a comprehensive water monitoring system covering the Yangtze River basin has commenced, accelerating the formation of a prototype digital twin of the Yangtze River.

A digital twin Yellow River project is advancing in an orderly manner, which aims at promoting the deep integration of the real-world Yellow River, Yellow River models, and a digital twin of the Yellow River.

In the development of digital twin water networks, a framework for constructing a national backbone digital twin water network has been completed. Progress has been made in the preliminary establishment of a digital twin for the first phase of the South-to-North Water Diversion Project’s central route, and 10 provincial-level pilot areas have achieved practical results in building their digital twin water networks. Efforts are also underway to advance the construction of digital twin water networks at the municipal and county levels.

Regarding digital twin projects, continuous iterative optimization is being carried out for key sites such as the Three Gorges Dam, Xiaolangdi Dam, Danjiangkou Reservoir, and Yuecheng Reservoir. From 2023 to 2025, 49 digital twin irrigation areas will be piloted. Besides, large and key medium-sized water conservancy projects newly constructed in 2025 will launch information infrastructure, digital twin platforms, and business application systems.

Digital twin in water conservancy enable more targeted management of rivers and lakes. China’s Ministry of Water Resources has established a national key rivers and lakes ecological flow monitoring and early warning platform. This platform gathers monitoring data such as water levels and flow rates from 283 ecological flow sections of key rivers and lakes. It enables real-time monitoring and early warning for 235 ecological flow control sections across 165 key rivers and lakes, as well as 65 water allocation sections.

A national water use management platform has been set up, allowing for dynamic monitoring of violations such as excessive water use, exceeding control limits, and lack of measurement for water users with permits. Up to now, 131,000 online monitoring points and 551,500 offline monitoring points nationwide have been connected to the platform.

Digital twin in water conservancy enable more science-based management of water conservancy projects.

In water conservancy engineering construction management system, information from over 40,000 enterprises, more than 1.07 million professionals, and over 420,000 project performance records and credit evaluations in the water resources industry have been consolidated.

In the water resources project operation management information system, electronic archives of over 90,000 reservoirs across nine industries, including water conservancy, energy, and transportation, have been shared.

In the rural water resources and hydropower information management system, basic and operational information for 520,000 centralized water supply projects, 42,000 small hydropower stations, and 7,326 large and medium-sized irrigation areas are updated annually, with a daily average of over 3,000 visits.

China’s Ninghai county produces 60 percent of world’s trekking poles

Published

on

By Liu Junguo, People’s Daily

At a sports equipment store near the Milan-Cortina Winter Olympics venues, shelves are filled with all kinds of winter sports gear. Among the items, a pair of beginner ski poles prominently displays its origin: “Made in China.” 

These poles hail from Ninghai county in Ningbo, east China’s Zhejiang province. This region, a powerhouse in outdoor equipment manufacturing, exports over 15 million ski and trekking poles annually to global markets.

Today, Ninghai commands nearly 60 percent of the global trekking pole market, with an annual output value approaching 1 billion yuan (about $145 million). Starting from scratch, the county has spent over two decades cultivating the industry and building technical expertise. It now boasts a complete  of Ninghai Better Outdoor Products Co., Ltd. (Better), visitors are greeted by a diverse array of trekking poles. One standout item is a training pole designed for novice alpine skiers. Made from aviation-grade aluminum alloy, the ski pole weighs less than 200 grams, offering both lightness and strength. Its handle, crafted from specialized materials, features an ergonomic design for trekking pole supply chain and is home to numerous well-known manufacturers and exporters.

Stepping into a showroomadded comfort.

“Overseas orders for this specific product for the 2025-2026 snow season alone have exceeded 800,000 units, a 30 percent increase year-on-year,” said Zhu Xuefeng, general manager of the company.

Better exemplifies the success story of Ninghai, but its origins trace back 26 years.

In 2000, Hu Jinxue from Ninghai came across aluminum alloy trekking poles from Germany at an overseas trade fair. He quickly recognized the potential of the outdoor equipment industry.

“At the time, Ninghai had a solid base in aluminum alloy forging, but its products carried low added value. Local enterprises were eager to upgrade, yet lacked a clear direction,” Hu recalled. 

After returning to China, he founded his company Xingda, introduced advanced technologies, and began producing trekking poles.

Leveraging strong expertise in metal processing and sustained technological upgrades, Xingda has grown into a leading industry player over the past two decades.

Even in its early stages, Ninghai adopted a forward-looking approach by identifying trekking poles as one of its key industries. A series of targeted measures has since helped turn it into a sector with an annual output approaching 1 billion yuan.

Inside Xingda’s smart factory, robotic arms move with precision, nano-level ironing activates fiber properties, and intelligent winding systems from dense, layered structures. Remarkably, within just 15 seconds, a roll of carbon fiber fabric is transformed into the high-strength shaft of a premium ski pole

As a key raw material for outdoor equipment such as ski poles, carbon shafts have long been expensive and subject to lengthy procurement cycles. Five years ago, Xingda still relied heavily on imports.

At that time, China depended on foreign suppliers for more than 90 percent of its high-end carbon fiber products, leaving independent innovation as the only sustainable path forward. Xingda responded by investing 70 percent of its annual profits into building a carbon shaft production facility and assembling a research team led by PhDs in materials science. After three years of intensive research, the company overcame key technical bottlenecks and achieved self-sufficiency in this critical material.

This breakthrough not only ensured stable supply and reduced costs but also led to a substantial leap in quality: Xingda’s carbon shafts are now 20 percent stronger than those produced by leading international brands..

Innovation is gaining momentum across Ninghai. Local manufacturers have filed more than 90 domestic patents, including utility models and industrial designs.

“This is one of our newly developed ski poles, designed to deliver high performance with environmental sustainability,” said Zhu Zhenkun, general manager of Ningbo Eastdragon Hardware Co., Ltd. (Eastdragon), displaying a sample. The eco-conscious design has proven highly popular in overseas markets.

In recent years, Zhu and his team have expanded internationally, where increasingly stringent carbon certification standards in Europe and the United States pose new challenges. In response, Eastdragon has not only improved product quality but also embedded green principles throughout its manufacturing process.

During production, leftover aluminum is recycled and reused, while new materials and processes are continuously explored. “After extensive testing of different handle materials, our research and development (R&D) team selected a biodegradable seaweed-based material,” Zhu said. “Handles made from this material offer a more comfortable grip and help reduce water use and carbon emissions.”

From a single product to a thriving industry, trekking poles have become a driver of local growth. Today, Ninghai has developed a complete industrial chain covering R&D and design, materials processing, component manufacturing, final assembly, and brand operations.  Today, the county hosts 34 leading enterprises and innovative small and medium-sized businesses within this specialized sector, solidifying its position as the world’s foremost center for trekking pole production.

China implements measures to counter Japan’s accelerating remilitarization

Published

on

By Zhong Sheng, People’s Daily

China’s Ministry of Commerce has announced the placement of 20 Japanese entities involved in enhancing military capabilities on its export control list. A further 20 Japanese entities, where the end-users and end-uses of dual-use items cannot be verified, have been added to a watch list.

These actions are taken to safeguard China’s national security and interests, fulfilling international non-proliferation obligations, and prevent Japan’s pursuit of remilitarization and nuclear armament. 

The measures are fully justified, reasonable, and lawful, demonstrating China’s commitment to the rule of law and its responsibilities as a major country.

This follows China’s January 6th announcement of strengthened export controls on dual-use items to Japan. The latest move explicitly names specific companies, translates earlier restrictions into targeted, enforceable, entity-based controls designed to effectively safeguard national security and regional peace and stability. 

According to international legal instruments such as the Cairo Declaration, the Potsdam Proclamation, and the Japanese Instrument of Surrender, Japan is required to be fully disarmed and must not maintain industries that would enable its rearmament. 

However, a number of Japanese companies, including Mitsubishi Heavy Industries, IHI Corporation, and Kawasaki Heavy Industries, have long been active in the defense sector, producing equipment such as naval vessels, fighter aircraft, and missiles. 

For instance, multiple subsidiaries of Mitsubishi Heavy Industries have participated in the development of Japan’s hypersonic weapon system, the Hyper-Velocity Gliding Projectile for remote island defense. Vessels built by Mitsubishi Shipbuilding have not only supported Japan’s maritime activities related to the Diaoyu Islands, but have also been supplied to the Philippine Coast Guard for use in the South China Sea, posing risks to regional peace and stability. 

China’s measures represent a targeted response to curb Japan’s development of offensive military capabilities and to uphold international law and the post-war international order.

Japan’s push toward remilitarization is following a clear trajectory, with a new military-industrial complex rapidly taking shape. 

In recent years, Japan has accelerated its military buildup, with defense spending rising for 14 consecutive years from fiscal 2012 through fiscal 2026, and effectively doubling within three years since 2022.

State-driven support has enabled Japanese defense contractors to reap substantial profits, even fueling what some describe as a “defense bubble” in capital markets. Data show that since November 2022, the stock price of Mitsubishi Heavy Industries has surged by more than 650 percent, IHI Corporation by over 480 percent, and Kawasaki Heavy Industries by more than 280 percent. In stark contrast, Japan’s manufacturing sector has recorded an average annual growth rate of less than 1 percent over the same period.

Since Sanae Takaichi assumed power, Japan’s remilitarization process has noticeably accelerated. War preparedness has been elevated to an overriding national priority, with further support extended to defense-related interest groups. 

Reports indicate that the Japanese government plans to address defense funding gaps through large-scale bond issuance and a special income tax, while also preparing to establish a “national intelligence agency” this year. 

In a recent policy speech in the House of Representatives, Takaichi asserted that Japan must fundamentally strengthen its defense capabilities and pledged to clearly communicate defense procurement needs to industry. These steps are likely to further bind Japan’s defense spending to specific industrial and corporate interests, creating a self-reinforcing cycle.

At the same time, right-wing forces in Japan have shown a growing ambition to pursue nuclear capabilities. In recent months, some Japanese politicians have openly advocated for nuclear armament and sought to revise the long-standing “Three Non-Nuclear Principles.” 

It is widely recognized as a “nuclear-threshold state,” having long produced and stockpiled plutonium far exceeding civilian needs. By the end of 2024, Japan possessed as much as 44.4 tons of separated plutonium. 

With a complete nuclear fuel cycle and advanced nuclear industry capabilities, Japan is technically capable of producing weapons-grade plutonium. Should right-wing political forces push Japan across the nuclear threshold, it would represent a severel breach of the global nuclear non-proliferation regime. 

A recent commentary by Singapore’s Lianhe Zaobao noted that nuclear non-proliferation remains central to international politics, and that Japan’s pursuit of nuclear weapons runs counter to the interests of Southeast Asia, where reducing arms races and minimizing the risk of conflict are essential to regional stability.

Japan’s remilitarization and nuclear ambitions pose a serious threat to regional peace and stability. The lessons of history make clear that appeasement of militarism amounts to a betrayal of peace. Countering the rise of right-wing forces in Japan requires concrete actions.

China’s law-based control measures aimed to prevent dual-use items from feeding into Japan’s military expansion and firmly curb any resurgence of militarism. China will work together with all peace-loving countries to uphold the post-war international order and jointly maintain regional security and stability.

Japan’s right-wing forces should recognize that a return to militarism leads only to self-destruction.  Any reckless attempt to challenge international justice and the global order is bound to meet firm resistance from the forces of justice around the world.

Integrating grassroots Perspectives into China’s legislative process

Published

on

By Zhang Tianpei, People’s Daily

Shanghai recently hosted a legislative consultation meeting on the draft law on promoting ethnic unity and progress at the Gubei civic center in Changning district’s Hongqiao subdistrict. 

The meeting fostered an engaged discussion, with attendees — including deputies to the National People’s Congress (NPC), academics, legal professionals, and members of non- Communist Party of China political parties — offering a wealth of valuable insights.

For Sheng Hong, an NPC deputy and Party branch secretary in the local Ronghua No. 4 Residents’ Community, this marked her 11th such consultation meeting within a year.

“Over the past year,” Sheng noted, “the scope of these legislative consultations have covered critical areas like ecological and environmental protection, urban governance, and public well-being. Participants contribute diverse perspectives and specific revision suggestions based on their professional expertise. This process effectively integrates grassroots voices and professional insights, ensuring draft laws are more grounded in reality.”

Sheng reflected on the evolution of public participation. Initially, residents visited grassroots legislative outreach offices primarily to understand how laws are made. Gradually, she observed, they evolved from passive recipients of legislative information into active advocates for legal awareness. Today, a robust network for gathering public opinion has taken shape, with participation expanding significantly.

A notable moment came in July 2025, Sheng recalled, when the State Council issued guidelines on gradually implementing free preschool education. Residents who had previously contributed to consultations on the draft preschool education law felt a profound sense of accomplishment.  “They recognized that ideas debated at our grassroots offices were being reflected in national policy,” Sheng explained.

She emphasized the shifting public expectations: “The focus is no longer just on whether laws exist, but on their effectiveness, practicality, and ability to solve real-world problems.” During the legislative process of the preschool education law, factors such as demographic changes in school-age populations and household financial capacity were fully considered. 

The resulting legislation aims to encourage increased government investment to reduce family burdens while simultaneously strengthening kindergarten teaching staff and improving facilities. “Beyond ensuring access,” Sheng stated, “the law actively addresses the public’s demand for high-quality early education, enhancing its relevance and timeliness.”

Promoting “public well-being” with “public voices,” a steady stream of practical, experience-based legislative suggestions is being conveyed from grassroots legislative outreach offices to the Great Hall of the People for legal adoption.

To date, the Legislative Affairs Commission of the NPC Standing Committee has set up 60 local legislative outreach offices nationwide. Additionally, provincial and city-level legislatures operate a network of over 7,800 such offices. In 2025 alone, opinions and suggestions were solicited from these offices on 26 draft laws, yielding more than 34,000 submissions, many of which have been adopted in legislation.

“Matters of the people should be discussed by the people themselves,” Sheng said. “As an NPC deputy from the primary level, I will continue to stay close to the people, listen to their voices, pool their wisdom, and bring more of their views to the Great Hall of the People, contributing to the practice of whole-process people’s democracy at the grassroots level and to improving the quality of legislation.”
