China is considering prohibiting exports of certain rare-earth magnet technology in a move that would counter the U.S.’s advantage in the high-tech arena. The revisions would either ban or restrict exports of technology to process and refine rare-earth elements. There are also proposed provisions that would prohibit or limit exports of alloy tech for making high-performance magnets derived from rare earths. Washington has since moved to forge a rare-earth supply chain on U.S. soil. China’s share of all rare earths produced globally dropped to roughly 70% last year from about 90% a decade earlier, according to the U.S. Geological Survey. At the same time, China still holds a tight grip on processing rare earths. Most rare earths extracted in the U.S. go to China for refining before being shipped back to the U.S.
