China has agreed to fast-track approvals for the shipment of rare earth minerals to the United States and some European Union nations.

US President Donald Trump said Chinese leader Xi Jinping has agreed to restart the flow of crucial rare earth materials, after announcing a new round of US-China trade talks will be held in London on Monday.

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.
