STOP CCP Act of 2025

S 1359 (STOP CCP Act of 2025) prohibits U.S. persons (including citizens, residents, and entities in the U.S.) from buying or selling publicly traded securities of Chinese entities operating in China's defense/military sectors or surveillance technology sectors, or entities owned by such companies. The bill requires the Treasury Secretary to expand the existing sanctions list (NS-CMIC List) to cover entities supporting China's military-industrial complex, including successors or financial service providers. It also closes sanctions loopholes by mandating that sanctions apply across all relevant laws unless the President waives them for national security reasons and reports to Congress. The law directly affects U.S. investors and financial institutions engaging with targeted Chinese companies.
