Promoting Agriculture Safeguards and Security Act of 2023 or the PASS Act of 2023 This bill establishes requirements to address the national security risk to the agricultural sector of the United States. Specifically, the bill prohibits persons who are acting on behalf of China, Russia, Iran, or North Korea from purchasing or investing in U.S. agricultural land and companies. The President may waive this prohibition, on a case-by-case basis, if the President determines that the waiver is vital to U.S. national security interests. The bill also places the Secretary of Agriculture on the Committee on Foreign Investment in the United States (CFIUS) and requires CFIUS to review certain transactions involving investments by foreign persons in the U.S. agricultural sector. Additionally, the Department of Agriculture must report on the risks that foreign purchases of U.S. businesses engaged in agriculture pose to the agricultural sector of the United States.
