STOP China Act

The STOP China Act prohibits federal funding for the procurement of certain vehicles (including buses) or related infrastructure from companies tied to China. It bans U.S. government contracts using "covered funding" for vehicles made by "covered entities" - defined as companies headquartered in China, controlled by China, or linked to Chinese state-owned entities, particularly those producing electric powertrains. The U.S. Trade Representative must publish and update a public list of these prohibited companies within 30 days of enactment, with quarterly updates initially. Exceptions allow funding for vehicle safety testing, investigations, and research, but the law directly affects federal transportation agencies, contractors, and companies with significant Chinese ownership or control.
