The United States has put forward a proposal to expand restrictions on American investments in sensitive technologies across several countries, including China, Russia, North Korea, Iran, and Cuba, due to national security concerns. The US Treasury Department revealed this proposed rule, which aims to increase oversight on investments that could potentially aid foreign nations in developing advanced military capabilities.
The new restrictions would cover a range of technologies such as artificial intelligence, supercomputing, quantum computing, semiconductors, biotechnology, and hypersonic systems. This initiative builds on an outbound investment security programme initially established by former President Joe Biden in 2023. Further expansion of the programme was legislated by Congress in December 2025 to include additional technologies and countries.
Under the proposed framework, investments exceeding $50,000 would be subject to review, though many financial transactions like certain stock purchases would remain exempt. The Treasury Department plans to evaluate public comments before finalizing the rule. The intent behind these restrictions, as stated by US officials and security experts, is to prevent American capital from bolstering technologies that could enhance the military strength of strategic competitors.
The proposal has faced criticism from China, which has urged the US to adhere to market principles and avoid disrupting legitimate international trade and investment. Chinese officials have warned that broadly interpreting national security concerns could damage business relations, and they have expressed readiness to take measures to protect China’s interests.
This proposal emerges amidst ongoing economic and technological competition between Washington and Beijing, where both nations have enacted restrictions on the export of sensitive technologies and strategic products, including advanced computer chips and rare-earth minerals. The proposed expansion signifies a further tightening of US oversight regarding overseas investments in advanced technologies, potentially impacting international businesses, investors, and global technology partnerships.
