The Secure Our Ports Act of 2024 prohibits U.S. port owners and operators from entering into contracts with Chinese, Russian, North Korean, or Iranian state-owned enterprises, or with foreign entities owned by those countries. The prohibition applies to contracts involving ownership, leasing, or operation of port facilities that are required to have Area Maritime Transportation Security Plans. This legislation would prevent these foreign entities from managing or controlling critical U.S. port infrastructure. The bill affects all U.S. ports subject to maritime security requirements and contains no specific funding or implementation timeline.
