Treasury Proposes Rule to Limit U.S. Investment in Advanced Technology in China and Other Countries of Concern

What happened

The Department of the Treasury published a proposed rule in the Federal Register on October 26, 2026 that would govern some investments United States persons make abroad ^[1]. Under it, United States persons would have to tell Treasury about some deals with foreign persons active in technologies the rule calls notifiable, and would be barred from other deals with foreign persons active in what it calls prohibited technologies ^[1]. It is a proposal, not a final rule: written comments must be received by December 7, 2026, and Treasury says a final version, with a start date, will follow ^[1][2].

The proposal carries out Title VIII of the Defense Production Act, added by the COINS Act ^[1]. Treasury's release says the COINS Act passed as part of the Fiscal Year 2026 National Defense Authorization Act ^[2]. Today's program reaches semiconductors and microelectronics, AI systems and quantum information technologies ^[1]. The new law widens that to high-performance computing and supercomputing, and to hypersonic systems ^[1]. Treasury has also put the biotechnology sector on the proposed prohibited list ^[1].

How it affects Americans

The rule applies to United States persons, so American investors and companies that put money into these sectors abroad would have to check whether a deal must be reported or is barred ^[1][2]. Treasury's summary says investors would be expected to look into a deal carefully before going ahead ^[2]. The text lists exceptions, including investment in publicly traded securities, bank lending and processing or clearing of payments ^[1].

The Veil Press view

Congress chose to write this program into law rather than leave it to an executive order alone ^[1]. That gives Americans a public process: anyone can comment on the definitions, the reporting duties and the penalties before the rule is final ^[2]. Readers with a stake in these sectors should read the text, because details such as de minimis values are left to the Secretary to set ^[1].
