China has broadened trade countermeasures against the United States after a series of Federal Communications Commission actions under Chair Brendan Carr targeted Chinese technology in U.S. supply chains. Beijing said it would tighten export controls on U.S.-bound drones and technology and sanction a U.S. testing and certification firm, while the FCC has over the past nine months barred imports of new Chinese drones, routers, inverters and robots, begun moving to block Chinese labs from testing electronics for the U.S. market, and drafted a ban on new Chinese data-center components. U.S. officials said the measures have White House backing and are framed as global national-security and re-industrialization rules, while China called them discriminatory and disruptive to supply chains; the escalation adds uncertainty ahead of a planned September meeting between President Donald Trump and Chinese President Xi Jinping, though analysts and earlier market pricing indicated the meeting was still likely to proceed.
