China surges ahead in humanoid robot deployment

China and Japan are accelerating the deployment of humanoid robots across key industries, driven by severe demographic pressures including aging populations and labor shortages, as the Asian nations surge ahead of Western competitors in mastering the technology. CATL, the world's largest battery manufacturer, initiated the first large-scale deployment of robots at its Luoyang factory in December 2025, while the State Grid Corporation of China launched a billion-dollar plan this year to deploy an army of humanoid robots for autonomous electrical grid maintenance. Japan Airlines announced a testing program for humanoid robots to transport luggage at airports, with a Unitree robot starting baggage handling operations at Tokyo's Haneda airport in May. China currently dominates the global robotics landscape, accounting for 54 percent of worldwide robot deployments with 295,000 industrial robots installed in 2024 alone, according to the International Federation of Robotics. The country's push is fueled by a projected shortage of 300 million migrant workers approaching retirement age who built China's modern infrastructure, combined with younger generations refusing to fill dangerous roles such as high-voltage power line maintenance. Companies including Unitree Robotics, AgiBot (which shipped over 5,100 humanoid robots in 2025 and assembled its 10,000th unit in April), Ubtech Robotics, and Xiaomi are scaling production rapidly, while Jensen Huang recently warned at Nvidia's GTC event that the US robotics industry remains deeply dependent on China's supply chain for rare earth magnets and components. Meanwhile, China's smartphone supply chain, including suppliers like Lingyi iTech and AAC Technologies, is pivoting to support the robotics sector, with Honor's humanoid robot D1 winning Beijing's recent robot half-marathon by adapting smartphone cooling technology to keep motors cool during the 21-kilometer race. The demographic imperative behind this robotics revolution extends beyond manufacturing into healthcare, as highlighted by Harvard medical anthropologist Arthur Kleinman, who argues that the US and China must transcend geopolitical tensions to address an unprecedented aging crisis. By 2050, nearly 30 percent of China's population, 40 percent of Japan's population, and over 20 percent of America's population will be over 65 years old, creating urgent demand for both robotic labor solutions and new approaches to elderly care. Kleinman, who will retire this year at 85, proposes that the US learn from China's long-term care insurance system while China adopts American nursing home models, suggesting that demographic cooperation between the two nations could prove as transformative as the current robotics race.
