Beijing barred dual-use exports to 10 U.S. entities, including rare earth producers MP Materials and USA Rare Earth, and blocked government procurement from 46 U.S. companies, widening pressure in the U.S.-China technology dispute.
China expanded restrictions on 56 U.S. companies on June 22, barring dual-use exports to 10 entities and prohibiting government procurement from 46 U.S. corporations, in what has been framed as retaliation for Washington's blacklist of Chinese technology firms. The export-control list includes MP Materials and USA Rare Earth, two companies tied to U.S. efforts to build a domestic rare earth mine-to-magnet supply chain that supports semiconductors, AI hardware, electric motors and defense manufacturing. Rare earth materials are essential to NdFeB permanent magnets used in hard drives, server cooling fans, robotics and other advanced equipment, and China's dominant position in mining and especially processing gives the move potential to disrupt supply chains for chips, magnets and advanced computing components. Beijing said the measures are intended to safeguard national security and fulfill non-proliferation obligations, while the broader package underscores how export controls and procurement restrictions are becoming central tools in the escalating U.S.-China technology and industrial rivalry.
