U.S. Treasury Moves to Clamp Down on High‑Tech Investments in China, Russia and Other Adversaries

Washington — The U.S. Treasury Department rolled out a draft rule on Thursday that would dramatically tighten the flow of American money into high‑technology projects in China, Russia, North Korea and a handful of other "countries of concern." The move builds on a series of restrictions that have been layering on each other for the past few years.

It all started back in 2023 when President Joe Biden signed an executive order aimed at curbing outbound investments in sensitive sectors such as semiconductors, quantum computing and artificial intelligence. That order gave birth to the Outbound Investment Security Program, a modest but growing effort to keep U.S. capital from feeding foreign military‑grade tech.

Fast‑forward to December 2025, and Congress codified the program into law with the Comprehensive Outbound Investment National Security Act. The legislation not only broadened the list of target technologies but also expanded the geographic scope to include Cuba, Iran, North Korea and Russia.

The newly proposed rule pushes the envelope even further. It would bring investments in hypersonic systems—those that can cruise at five times the speed of sound—supercomputing, biotechnology and what the Treasury loosely calls “superintelligence” (AI) under its jurisdiction. In the words of Craig Singleton, a senior fellow at the Foundation for Defense of Democracies, the rule "sends an important signal to markets that Washington is tracking where U.S. capital is flowing and what capabilities it is helping build."

Practically speaking, the rule would only apply to deals worth more than $50,000. Smaller stock purchases and routine financial transactions would be exempt, but anything larger that touches the listed technologies would have to clear a new compliance hurdle. Jason Chipman, a former Justice Department cyber‑law specialist now with WilmerHale, warned that companies will need "more substantial compliance programs to manage risk."

Public comments are being solicited before the Treasury finalizes the regulation. Former trade official Ryan Majerus, now a partner at King & Spalding, described the proposal as "just the first step" in a longer journey toward tougher enforcement.

The backdrop to this regulatory push is the ongoing techno‑economic rivalry between the United States and China, a rivalry that has already produced tariffs, export bans on advanced chips and rare‑earth restrictions on both sides. Even after a brief diplomatic thaw earlier this year—when President Donald Trump temporarily lifted sanctions on Russia after a diesel deal with Vladimir Putin—the competition remains fierce.

Last summer, Treasury demonstrated its willingness to police the new rules, slapping a $200,000 fine on a U.S. firm that failed to report a $92,500 investment in a Chinese AI and robotics startup. That case illustrates how seriously the agency is taking the task of tracking capital that could accelerate foreign military capabilities.

In short, the proposed rule is a clear signal that Washington intends to keep a tighter leash on American dollars that might end up powering the next generation of foreign weapons. The final shape of the rule will depend on the feedback it receives, but the trajectory toward stricter outbound investment scrutiny appears unmistakable.
