This legislation, known as the Comprehensive Outbound Investment National Security Act of 2025, is designed to safeguard United States national security by addressing financial flows to countries of concern, particularly the People's Republic of China. Congress asserts that restricting certain outbound investments is crucial to prevent foreign adversaries from exploiting U.S. capital for military modernization, surveillance states, and human rights abuses. The Act is set to terminate seven years after its enactment. Title II of the bill grants the President authority to impose sanctions on "covered foreign persons" from countries of concern. These sanctions prohibit U.S. persons from investing in or purchasing significant equity or debt instruments of foreign entities determined to be involved in the defense, related materiel, or surveillance technology sectors. A "country of concern" is defined as the People's Republic of China, including Hong Kong and Macau, and a "covered foreign person" includes entities linked to the government or military of such countries. Title III amends the Defense Production Act of 1950 to establish a new framework for outbound investment review. It authorizes the Secretary of the Treasury to prohibit U.S. persons from engaging in "covered national security transactions" involving "prohibited technologies" in countries of concern. These prohibited technologies include advanced semiconductors, artificial intelligence systems, quantum information technologies, high-performance computing, and hypersonic systems. Additionally, the bill mandates that U.S. persons provide notification to the Secretary of the Treasury for covered national security transactions involving "notifiable technologies," which encompass a broader scope of the same critical technology areas. The Secretary is directed to issue regulations for both prohibitions and notifications, aiming to balance national security protection with minimizing compliance burdens for affected parties. These regulations will include processes for non-binding feedback and self-disclosure of violations. The legislation outlines penalties for violations, including civil penalties and the potential for divestment of non-compliant investments. It also encourages multilateral engagement with U.S. allies and partners to promote coordinated efforts in restricting such investments. The Secretary is authorized to establish a public database identifying covered foreign persons involved in prohibited or notifiable technologies. Finally, Title IV requires the President to biennially report to Congress on whether certain PRC persons, already identified on other U.S. government lists (such as the Military End-User List or the Entity List), should be included on the Non-SDN Chinese Military-Industrial Complex Companies List. This aims to streamline the identification and listing of entities posing national security risks. The bill authorizes $150 million for the Department of the Treasury for implementation and outreach, and grants special hiring authority to support these new responsibilities.
