China’s exports of rare-earth magnets increased nearly threefold in June from the previous month, after the country lifted some export controls on the critical industrial inputs following a deal with the U.

The numbers mark a recovery in the flow of the critical minerals that are used in electric vehicles and wind turbines following a Sino-U.S. trade deal.

China’s exports of rare earth magnets to the U.S. in June rose more than sevenfold from May, signaling a sharp rebound in supply, according to Reuters. China’s rare earth magnet exports rose 157.5% from May but are down 18.
