China bans exports to three U.S. firms over national security, citing tech competition.

China’s Ministry of Commerce added three U.S. companies to its export control list, banning exports of dual-use items and halting ongoing shipments. The move, citing national security and international obligations, restricts access to sensitive technologies and follows broader efforts to strengthen China’s export controls. While specific reasons were not disclosed, the action reflects ongoing U.S.-China tensions over technology and trade, with Beijing using export restrictions as a tool in its economic and strategic competition.
