This bill authorizes the President to bar ships from entering U.S. ports if they have recently called at a port in a Western Hemisphere free-trade partner country that was seized from an American owner without fair compensation. By restricting access to U.S. ports, the bill seeks to pressure foreign governments to resolve property disputes involving American-owned ports or terminals. Exceptions are made for emergencies, allowing vessels in distress to enter. The measure is intended to defend U.S. property interests overseas and may have significant implications for international shipping and trade relations.
