The U.S. Treasury Department announced a new regulatory proposal on Thursday aimed at restricting outbound American investments in high-tech sectors within nations identified as adversaries. The proposed rule falls under the Outbound Investment Security Program (OISP) and is designed to prevent U.S. capital and expertise from bolstering the military and intelligence capabilities of foreign powers.

The scope of the proposal covers several critical technology areas, specifically focusing on artificial intelligence, quantum information technologies, high-performance computing, and supercomputing systems. Additionally, the rule includes restrictions related to hypersonic systems. These measures are intended to close gaps in existing export controls by monitoring and potentially prohibiting private equity, venture capital, and joint venture investments that could provide strategic advantages to countries of concern, including China, Russia, and North Korea.

While the Treasury Department frames the move as a necessary step to protect national security, the proposal highlights the ongoing tension between maintaining an open global economy and safeguarding domestic technological dominance. The rule is currently in the proposal stage, meaning it is subject to public comment and potential revisions before final implementation. The initiative reflects a broader bipartisan push in Washington to decouple sensitive supply chains and limit the transfer of dual-use technologies that could be repurposed for military applications by adversarial regimes.
