The United States has proposed expanding its restrictions on American investments in sensitive technologies in countries deemed national security threats, including China, Russia, North Korea, Iran, and Cuba. The US Treasury Department announced this proposed rule as part of efforts to enhance oversight of investments that might enable foreign nations to develop advanced military and strategic capabilities.
The proposed restrictions would focus on technologies such as artificial intelligence, supercomputing, quantum computing, semiconductors, biotechnology, and hypersonic systems. This initiative builds on an outbound investment security program established under President Joe Biden in 2023. In December 2025, Congress passed legislation to broaden the program’s scope to include additional technologies and countries.
Under the new framework, investments exceeding $50,000 could fall under these restrictions, although many financial transactions, including some stock purchases, would remain exempt. The Treasury Department plans to review public comments before finalizing the rule.
US officials and security experts argue that these restrictions aim to prevent American capital from supporting technologies that could bolster the military strength of strategic competitors. Businesses could face more stringent compliance requirements to ensure their investments adhere to the proposed rules.
China has criticized the proposal, urging the US to respect market principles and avoid meddling in legitimate international trade and investment. Chinese officials warned that interpreting national security concerns too broadly to restrict economic cooperation could damage business relations and stated that Beijing would closely monitor developments to protect its interests.
This proposal comes amid ongoing economic and technological competition between Washington and Beijing, with both countries imposing restrictions on sensitive technology exports and strategic products, such as advanced computer chips and rare-earth minerals. The expansion signals a further tightening of US oversight on overseas investments in advanced technologies, potentially impacting international businesses, investors, and global technology partnerships.
