On June 22, 2026, China’s Ministry of Commerce put 10 US companies on its export control list. Neither Chinese nor foreign firms can sell those companies any goods that have both civilian and military uses. Most of them build drones, radar, aerospace systems, and military vehicles. Two of them—MP Materials and USA Rare Earth—are the federally backed American companies furthest along in building a mine-to-magnet chain.
Beijing said its move was a response to a similar move by the Pentagon. My interpretation is that China picked MP Materials and USA Rare Earth because they are best placed to reduce America’s need for Chinese processing.
An extension of the pause on Nov. 10 would honor the truce, but the heavy rare earth licenses and the June 22 ban on the targeted firms would still apply. The truce means both parties get to play nice. It doesn’t mean they are being nice.
Three paths
For the US, leaving processing in China is the fastest and cheapest solution, but that leaves it exposed to Beijing’s restrictions.
Rebuilding a US rare earths supply chain would remove most US dependence on China for rare earths and the political leverage it implies. But it would take longer, startup costs run to the billions of dollars, and separation produces acidic, and sometimes radioactive, residues.
Building a supply chain with allies such as Australia or Japan, both of which have started to build capacity, would lower the risk of the US being cut off unilaterally. Japan has run this play with some success, but the suspended Chinese rules affect any use of their technology abroad.
President Xi’s Sept. 24, 2026, meeting with Trump may help determine the status of the Nov. 10 restrictions, but the larger conflict over leverage will continue.
