China announced on December 3 that it will halt exports of gallium, germanium, antimony, and graphite to the U.S., a response to the Biden administration's latest round of technology export controls. This development intensifies the ongoing tech conflict as Washington restricts trade with over 140 Chinese firms, citing national security risks. Chinese industry groups are urging local firms to avoid U.S. chip products, claiming they are no longer safe. The situation reflects rising tensions preceding President-elect Donald Trump's return to office, where he has pledged to further challenge China's technology sector.
