To prohibit entities owned or controlled by foreign governments from conducting certain operations at seaports in the United States, and from entering into agreements to conduct such operations.

H.R. 4839 is a legislative proposal that would prohibit any company owned or controlled by a foreign government from managing or operating cargo and passenger activities at United States seaports. Under this bill, these foreign entities would be barred from overseeing the movement of imported and exported goods, as well as the arrival and departure of vessel crews. The measure aims to restrict port operations to private or domestic entities by imposing civil financial penalties on any person or organization that enters into prohibited contracts with foreign government-controlled firms.
