On October 23, 2026, the U.S. Treasury Department proposed new regulations to restrict high-tech investments, including AI, to adversarial nations such as China, Russia, and North Korea. This proposal is part of the Outbound Investment Security Program (OISP) and follows the 2025 Comprehensive Outbound Investment National Security (COIN) Act. Investments exceeding $50,000 in specific technologies like hypersonic systems, quantum computing, and biotechnology will be affected. The regulations aim to prevent adversaries from leveraging U.S. investments for military and surveillance advancements. The Department of Homeland Security recently ordered the removal of products from the Chinese AI startup DeepSeek from federal IT systems due to security concerns. The Chinese government has condemned these actions, claiming they politicize technology and trade. The proposal is open for public feedback before finalization.
