How robots and AI are quietly rewiring China’s factory floor

Across China’s enormous manufacturing belt, the most noticeable change isn’t a new product line but the absence of people on the shop floor. The country’s biggest appliance makers, steel producers and garment firms are retooling their plants with robots, sensors and AI systems that can run complex operations without the break-neck supervision earlier automation required. The shift is driven by a single anxiety: China’s position as the world’s primary factory base is no longer guaranteed, the Wall Street Journal reported.

For decades, China relied on cheap labour migrating from inland provinces to coastal factories. That pool has shrunk. Wages have risen, younger workers are reluctant to take up repetitive factory jobs, and global pressure on Chinese exports has hardened. With the US raising tariffs and promising to pull production back home, Chinese planners see automation as essential to staying competitive. Earlier this year, senior officials from the Ministry of Industry said openly that AI-powered manufacturing is no longer “optional”, but a necessary response to global reshoring.

China installed nearly 300,000 industrial robots last year, more than the rest of the world combined. It now has over two million operational units across its factories. While the US and Europe are also automating, China’s advantage lies in the speed of adoption and the scale at which companies are re-engineering entire plants. Executives at several large groups describe the new generation of robotic systems as “thinking nodes”, where machines, sensors and AI models interact to adjust production with minimal human intervention.

The transformation is most visible at companies such as Midea, one of the world’s largest home-appliance manufacturers. In Jingzhou, its washing-machine plant runs under an AI-based command system engineers call a “factory brain”. This system coordinates dozens of robotic arms, checks components through high-speed imaging and flags inconsistencies in real time. Tasks once spread across multiple teams—inspection, alignment, adjustments on moving assembly lines—are increasingly managed by the AI system. At certain points the lights are dimmed because humans are scarcely required.

Alongside new startups, legacy technology companies such as Huawei have taken on a central role in equipping factories with their own AI models. Cement giant Conch has worked with Huawei to design software that monitors conveyor belts, predicts the strength of clinker and adjusts raw materials without needing constant oversight. Such incremental efficiencies—cutting energy use in kilns or reducing the number of defective batches—translate into large savings in an industry that runs on volume.

Ports, which sit at the heart of China’s export machine, are experiencing similar changes. At Tianjin, one of China’s busiest ports, trucks move containers without drivers and cranes operate with little manual guidance. Scheduling that once took a day can be completed in minutes. A system called OptVerse helps manage container movement by calculating thousands of variables instantly. Port executives say employment has already dropped by more than half compared with traditionally run terminals.

The rapid rollout has its risks. Too much automation could displace more workers than China can absorb. But the government’s view is that a shrinking population makes this a smaller concern than it would have been 20 years ago. Beijing appears confident that productivity gains will outweigh the social pressure. China’s leadership also knows that the global AI race is not only about futuristic breakthroughs but about who can apply the available technology faster and at scale.

As the US debates the pace of automation—particularly in ports and logistics—China is moving ahead without hesitation. The country’s bet is simple: if its factories can produce mainstream goods faster and cheaper than any rival, no tariff wall can permanently erode its manufacturing dominance. The new robots in China’s factories and ports are less about replacing human workers and more about defending China’s place in the world’s supply chain.
