On October 28, 2024, the US Treasury issued final regulations for the Outbound Investment Security Program (OISP), effective January 2, 2025. The OISP restricts or requires notifications for US investments in key technology sectors, particularly regarding China. It applies to US persons, defined as citizens and entities under US laws, and covers transactions with “covered foreign persons” involved in sensitive activities. The regulations aim to limit access to US capital and technology by foreign entities posing national security risks. Violations can result in significant fines or imprisonment, necessitating compliance measures for affected entities.
