Suppliers of three big U.S. automakers, General Motors,, Ford and Jeep-maker Stellantis got clearance for some rare earth export licenses on Monday, one of the two sources said.

China has reversed its decision to restrict the export of rare earth minerals, giving Detroit’s Big 3 access to critical minerals used in the manufacture of electric vehicles and catalytic converters.

China views its rare earths as a national security issue, not a trade one, and that’s why Beijing is unlikely to loosen controls any time soon, experts say.
