WASHINGTON, October 23, 2026 — The U.S. Treasury Department has proposed a broader framework for screening American investments in sensitive technologies linked to countries it designates as national-security concerns. The proposal would extend the government’s outbound-investment programme under the Comprehensive Outbound Investment National Security Act of 2025, with China remaining a central focus.
The proposal is not a blanket ban on doing business with China, and it is not yet a final rule. Reuters reported on October 22 that Treasury will accept public comments through December 7. The draft would require notifications for certain transactions and prohibit specified investments in advanced artificial-intelligence technologies, while widening the covered technology list to include biotechnology.
Which technologies and countries are covered?
The proposed framework covers advanced semiconductors and microelectronics, artificial intelligence, quantum information technologies, high-performance computing and supercomputing, hypersonic systems, and certain biotechnology applications. Treasury’s stated policy rationale is to prevent U.S. capital and the expertise, relationships and other benefits that can accompany investment from helping develop technologies that could support military, surveillance or other national-security capabilities.
Reuters reported that the proposal names China, Russia, Iran, North Korea and Cuba as countries of concern. Venezuela has been removed from the list in the proposal following the change in government there. The final legal treatment of particular transactions will depend on the rule’s definitions, exceptions and any subsequent changes made after public comments.
What would change for investors?
Under the proposal, some transactions would require notification to Treasury, while specified investments in artificial intelligence would be prohibited. Reuters reported that the proposal includes exceptions for certain publicly traded securities and transactions valued below $50,000, and allows requests for exemptions where a transaction is considered to be in the U.S. national interest. Investors should not assume every investment in a listed country is covered or that every exception applies automatically; the legal definitions and transaction details matter.
The proposed rule builds on an existing outbound-investment programme that already restricts or requires reporting for certain U.S. investments connected to China, Hong Kong and Macau in semiconductor, quantum and AI sectors. Treasury’s existing programme remains in force while the new statutory framework is developed. Companies and funds with exposure to sensitive technology should continue to follow current requirements rather than wait for the proposal to become final.
Why biotechnology is being added
Biotechnology can support civilian research and healthcare, but some applications also have potential military or surveillance uses. The administration’s proposal would bring specified biotechnology activities into the same national-security screening framework used for advanced computing and related fields. The scope of those definitions will matter to investors, researchers, pharmaceutical firms and venture-capital funds, especially where a transaction combines financing with access to technical know-how or data.
What happens next?
The public-comment period gives investors, companies, researchers and other stakeholders an opportunity to challenge definitions, flag unintended effects and request clarity. Treasury may revise the proposal before issuing a final rule. Until then, the December 7 deadline is a consultation milestone—not the date the proposed restrictions automatically take effect.
The policy highlights a wider tension in global technology markets: governments want cross-border investment and innovation, but they are increasingly willing to limit capital flows when technologies are considered strategically sensitive. For companies operating internationally, compliance teams will need to track both U.S. investment restrictions and China’s own export-control measures.
