China supplies more than 90% of the world's magnets, a Pentagon rule requires defense contractors to source them outside China from January 2027, and China's September chip exports rose 136%.

The United States needed roughly 48,000 metric tons of the most common type of rare-earth magnet last year, and domestic sources supplied just 300 tons, according to OilPrice. The rest came from abroad. China makes more than 90% of the world's supply. These magnets go into electric motors, wind turbines, guided munitions, drones and the cooling and power systems of data centers.
The gap now has a deadline. The Department of Defense has set January 2027 as the date by which American defense contractors must source magnets from manufacturers outside China. MP Materials, the only significant US rare-earth miner and processor, has reported output of about 1,300 tons of the oxide used to make these magnets, still far below the demand figure. Beijing has shown it will use its position. In April 2025 it put export controls on magnets and seven medium and heavy rare earths.
China's own figures show its technology industry growing on the other side of the export-control divide. Integrated-circuit exports rose 136% to $45 billion in September. Xinhua, the state news agency, ran a feature on Sunday promoting what it called an "unlikely" AI computing hub inside China. Beijing has been placing computing clusters in western provinces where electricity is cheap.
The two sides hold different kinds of leverage. Washington controls the most advanced chips and the tools to make them. Beijing controls the processed minerals that turn those chips into weapons, vehicles and powered data centers. China's September export data show that US controls have not stopped Chinese chips from reaching foreign buyers in volume.
Part of a tracked trend
China Builds a Parallel Technology Stack
United States export controls push China to develop its own chips, computing hardware and artificial-intelligence systems, accelerating a split of global technology into competing spheres that reshapes supply chains and standards.
MP Materials and other non-Chinese magnet makers in the United States, Japan and Australia gain pricing power and an argument for subsidies from the gap between 48,000 tons and 300 tons. Beijing can cite the same figures as evidence of its leverage over US defense supply chains.
The demand and supply figures match Rare Earth Exchanges' report and other trade coverage. But the 300 tons is 2025 output, and the same coverage expects US capacity to reach about 5,000 tons by the end of this year. China's customs totals for integrated-circuit exports also do not separate advanced chips from mature-node chips, so the 136% rise does not show that US controls on advanced chips have failed.
An open-source-intelligence read of how likely this story is true with its real nuance, not a judgment of any outlet. It assesses the claim, weighing independent and adversarial reporting. How we label confidence.
What this means
The mechanism is input dependence. Every US defense program and electric-motor supply chain that uses neodymium magnets depends on a Chinese licensing decision until non-Chinese capacity reaches thousands of tons, not hundreds. US defense primes, automakers and motor makers carry that risk, and so do the data-center builders whose cooling and power equipment uses the same magnets. Non-Chinese magnet makers in Japan, the United States and Australia gain pricing power ahead of the 2027 deadline. The market prices this as a slow industrial-policy story. It underweights how short the timeline is: a 2027 sourcing rule against current US output of 300 tons means contractors will either get waivers or pay sharply higher prices. The precedent is China's 2010 restriction of rare-earth exports to Japan, which drove a price spike and, over about a decade, a costly Japanese effort to diversify supply that cut but did not end its dependence. The likelier outcome is that the Pentagon grants waivers or delays the 2027 deadline in stages over the coming year while it funds new capacity. This depends on non-Chinese capacity staying far below demand. The desk's read is wrong if new US and allied magnet plants announce volumes in the thousands of tons before the deadline.
