Japan Asks US for Help in Easing China’s Rare-Earth Export Controls

Japan has asked the United States to help persuade China to ease rare-earth export controls, amid concerns that dwindling yttrium supplies could disrupt industries. The request follows restrictions that have sharply reduced exports of the mineral, used in jet engines, automotive parts and semiconductor manufacturing. Japanese officials warn inventories are falling and shortages could become severe by year’s end. Washington has also pressed Beijing to resume rare-earth shipments to Japan. US defense contractors rely on Japanese components containing yttrium too.
