China has long been the backbone of the global container industry. In 2024, the country produced more than 8.1 million twenty-foot equivalent units (TEUs), up 268.2 percent year on year, accounting for 96 percent of global output. 

Today, these steel structures transcend their traditional role as standardized shipping units, evolving into creative urban modules and critical infrastructure for renewable energy sectors.

At Dong Fang International Container’s Jiangsu facility, rows of newly manufactured units await shipment to European clients via Shanghai’s Yangshan Port. Though externally identical to standard containers, their interiors reveal sophisticated battery arrays integrated with safety systems, thermal controls, and environmental management technology — essentially transforming them into massive “power banks.”

“Modern container manufacturing extends far beyond welding steel boxes,” explains Zhai Jianxing, the company’s technical director. “Material science is now paramount.” Energy storage containers demand radically different specifications from shipping units: requiring 20+ year lifespans (versus 2-year warranties for standard units) and meeting rigorous standards for explosion prevention, fire resistance, and corrosion protection.

To meet these challenges, manufacturers have pioneered advanced materials. Traditional weather-resistant steel with triple-layer paint has been replaced by zinc-aluminum-magnesium coated steel, offering self-healing properties and exceptional resilience in high-salinity coastal environments. 

Other innovations have followed. Ceramic wool insulation has been added for fire protection; environmentally friendly water-based coatings have replaced traditional oil-based paints; and bamboo flooring has been introduced to reduce reliance on timber resources.

These advancements enable containers to serve diverse new functions across renewable energy generation, computing centers, and modular construction. Beyond industrial applications, containers are revitalizing communities.

In Huanghu township, Hangzhou, east China’s Zhejiang province, two stacked containers sit in an open space in a smart agriculture park. Inside, lettuce grows on metal racks while tomatoes thrive under artificial lighting. This mobile, digitally controlled plant factory offers a striking example of innovation.

“Through precise environmental control systems, we tailor light formulas, nutrient solutions, and temperature and humidity conditions for plants,” said Lei Lina, head of the facility. As a flexible cultivation unit, container-based plant factories can be assembled and transported like building blocks, making it easier to supply fresh produce locally.

Meanwhile, along the East Taihu Lake in Suzhou, Jiangsu province, visitors are drawn to a stylish cafe. Built from four specialized containers, the structure combines aesthetic appeal with practical functionality.

“To adapt these containers for civilian use, we incorporated soundproof panels, fire-resistant magnesium oxide boards for flooring, and high-strength steel just 6 millimeters thick for structural support,” said Qian Xiaohui, head of Suzhou Zhongnan Steel Structure Co., Ltd. “This ensures safety while maximizing interior space.”

The expanding versatility of containers is closely tied to advances in smart manufacturing.

At an intelligent factory of a logistics equipment company under China International Marine Containers (CIMC) in Ningbo, Zhejiang province, more than 500 robots perform welding, assembly, and painting with millimeter-level precision. Steel plates are transformed into standard dry cargo containers along automated production lines.

“By leveraging 5G, artificial intelligence (AI), and digital twin technologies, we’ve achieved automated and intelligent production,” said Zhang Kechao, the company’s general manager. “Per capita efficiency on a single production line has increased by over 30 percent, and capacity utilization has reached 95 percent.”

At CIMC’s refrigerated container base in Qingdao, east China’s Shandong province, AI-powered industrial models enable the production of a high-end refrigerated container in just 220 seconds on average. In Xinhui, south China’s Guangdong province, more than 300 automated spray guns operate on fully automated powder-coating lines, ensuring seamless and comprehensive coverage.

From a “green revolution” in materials to breakthroughs in application scenarios and upgrades in intelligent manufacturing, the transformation of China’s container industry reflects the integration of new quality productive forces into traditional sectors. 

As technologies such as AI and the Internet of Things continue to develop, this “Made-in-China” product is poised to play an even greater role in global trade, energy transition, and urban development.

China’s steel industry is accelerating its transformation through structural upgrades and the deep integration of artificial intelligence (AI), strengthening its capacity to supply high-end materials for advanced manufacturing.

At Shougang Zhixin Qian’an Electromagnetic Material’s production line, robotic arms handle coils of high-performance electrical steel with precision. Among these is an ultra-thin variant measuring just 0.1 millimeters — the world’s first when launched in August 2025.

Electrical steel is a key material for new energy vehicle motors, high-end home appliances, and ultra-high-voltage transformers, said An Dongyang, chief technical expert of the company. 

“This material is critical for new energy vehicle motors, premium appliances, and ultra-high-voltage transformers,” explained An Dongyang, the company’s chief technical expert. Developed to meet demands for smaller, more powerful EV motors, the innovation attracted immediate interest from over a dozen automakers. Compared to standard 0.25mm steel, it reduces energy loss by over 30% and significantly improves efficiency, extending vehicle range.

“Today, one in three new energy vehicles in China uses this product” An said, adding that  specialized applications for humanoid robots are now being explored.

As a cornerstone of China’s industrial system, the steel sector has in recent years stepped up efforts to upgrade its product mix and expand the supply of advanced materials. In 2025 alone, nearly 20 world’s first steel products were launched.

China’s top steel manufacturers are powering major national breakthroughs across key industries. Masteel, a subsidiary of China Baowu Group, produces high-speed railway wheels for the CR450, the world’s fastest bullet train. Pangang Group Company Limited, under Ansteel Group, supplies special blade steel for China’s first homegrown F-class 50MW heavy-duty gas turbine. Nanjing Steel Group provides exclusive steel plates and sections for Adora Magic City, China’s first large domestically built cruise liner.

These developments reflect a broader shift in demand. In 2025, steel used in construction accounted for 49 percent of total demand, down from 58 percent in 2020, while manufacturing’s share rose from 42 percent to 51 percent.

“For the first time in China’s history, steel demand from manufacturing has surpassed that from construction,” said Jiang Wei, vice chairman and secretary-general of the China Iron and Steel Association. “This reflects the industry’s proactive adaptation to changing demand and its push toward higher-quality development.” 

During the 14th Five-Year Plan period (2021-2025), China’s steel self-sufficiency rate remained close to 100 percent, ensuring strong support for the broader economy.

Alongside product upgrading, digital and intelligent technologies are reshaping production processes.

At a plant of HBIS Group’s Tangsteel Company in Tangshan, north China’s Hebei province, molten steel at 1,650 degrees Celsius poured from a converter. In the control room, chief expert Zhou Quanlin monitored operations on a screen. With a few taps, the system autonomously completed key smelting processes.

Achieving precise temperature control in steelmaking is highly complex. Last year, HBIS Group integrated large AI models into its proprietary platform to develop an intelligent steelmaking system, now applied in core production stages.

“In the past, we relied on experience, watching the flame and judging when and how much material to add,” Zhou explained. “Now, the AI model analyzes vast historical data along with real-time signals such as furnace sound and gas emissions to precisely control reactions inside the furnace.”

The results have been significant: since deployment, steelmaking efficiency has increased by 10.3 percent, while overall energy consumption has dropped by about 10 percent.

AI is reshaping every link of China’s steel industry, far beyond steelmaking itself. Steel manufacturer Baosteel uses an AI cloud surface inspection system. It accurately spots 96 percent of critical material flaws, and cuts missed inspections by 35 percent. 

Meanwhile, Shanghai Steel Information Technology Co., Ltd. leverages AI for smarter supply chain operations. It handles more than 10 million daily transactions with over 95 percent accuracy, and completes billions of intelligent trade matches efficiently.

Today, AI integrates across steel production, manufacturing, and operations, accelerating industry-wide intelligent transformation. Over 95% of major steel enterprises tracked by the China Iron and Steel Association have incorporated digitalization into core strategies, shifting from pilot projects to systematic implementation.

As a pillar industry of the national economy, the steel sector boasts massive data resources and diverse industrial application scenarios, and thus serves as a perfect platform where next-generation AI can make a difference, said Zhang Longqiang, president of the China Metallurgical Information and Standardization Institute. 

“AI-steel integration holds immense long-term potential,” he added. “With large language models permeating production chains, industry-wide intelligent upgrading will accelerate significantly.”

China’s express delivery sector handled a total of 47.73 billion parcels in the first quarter of 2026, up 5.8 percent year on year. According to statistics released by China’s State Post Bureau on April 22.

As a key link connecting production and consumption, the express delivery industry is often regarded as a real-time barometer of economic activity. What does this growth reveal about China’s economy?

While growth moderated compared to previous years, seasonal factors played a role: the shifting Spring Festival holiday and extended break disrupted early-year operations. By March, normal activity resumed with demand rebounding strongly — parcel volumes already exceeded last year’s levels.

Deeper analysis shows sustained momentum since China’s 14th Five-Year Plan period (2021-2025). Parcel volumes rose annually, with each new 100-billion-parcel milestone achieved faster than the last. This steady growth in the first quarter of 2026 — the inaugural year of the 15th Five-Year Plan period (2026-2030) — provides a window into China’s economic transition toward new growth drivers and higher-quality development.

Moving toward the new — what is driving this “new” momentum?

It comes from technology. 

At Jilin’s Chagan Lake winter fishing grounds, autonomous last-mile vehicles now integrate with rail, road, and air networks — delivering fresh catch to Beijing and Shanghai overnight. In Yunnan and Guizhou tea regions, drones have established “aerial tea routes,” reducing order damage by 40 percent.

Domestic firm Neolix nearly tripled autonomous vehicle deliveries year-on-year in the first quarter. Expanding unmanned delivery capabilities helps the sector cut costs, improve service quality, and build new competitive advantages.

It also comes from new scenarios. 

Delivery firms now partner with tourism companies to serve surfing enthusiasts with equipment shipping, collaborate with manufacturers on specialized cargo like EV batteries, and establish urban “micro-warehouses” for flexible storage.

Driven by market demand, the industry continues to innovate on the supply side, extending its reach into households and cross-sector operations while expanding market opportunities.

Behind the faster application of new technologies and the constant emergence of new scenarios lies the strength of China’s complete industrial system and enormous domestic market. Relying on these advantages, as more technological innovation and scenario innovation move in sync, the express logistics sector is accelerating its expansion and upgrading, injecting strong new momentum into economic circulation.

Moving toward higher quality — where is this “higher quality” reflected? 

It is reflected in a better structure.

Since 2021, China’s central and western regions’ share of national delivery volume grew cumulatively by 7.5 percentage points, reaching 32 percent in the first quarter of 2026. These areas are becoming new growth engines, reflecting progress in e-commerce expansion westward and extended “free shipping” coverage — signaling more balanced regional development.

Recent modest price increases (including fuel surcharges) reflect more than rising oil costs. Since 2025, China’s measures to curb destructive price wars have taken effect. Multiple provinces have implemented rate adjustments alongside service quality improvements.

While these corrections contributed to short-term growth moderation, they signal a positive long-term shift: the industry is transitioning from cutthroat pricing to value-based competition.

Both regional rebalancing and market optimization stem from China’s advancement of a unified national market. By removing systemic bottlenecks, improving circulation efficiency, and ensuring fair competition, this integrated market continues unlocking new vitality for the sector.

China operates the world’s largest delivery network in scale and coverage. This achievement rests on tangible capabilities and is propelled by the pursuit of advanced productive forces. As this dynamic, resilient logistics network evolves, it will increasingly serve as a vital indicator of high-quality development — reinforcing China’s economic vitality.
