China has stopped exporting rare earths to everyone, not just the U.S., cutting off critical materials for tech, autos, aerospace, and defense

After Trump unveiled his “Liberation Day” tariffs on April 2, China retaliated on April 4 with its own duties as well as export controls on several rare earth minerals and magnets made from them.

So far, those export controls have translated to a halt across the board, cutting off the U.S. and other countries, according to the New York Times.
