The foreign and intergovernmental relations of Puerto Rico are governed by the Commerce and Territorial Clause of the Constitution of the United States. Because of this, they are subject to the plenary powers of Congress. Nonetheless, Puerto Rico has established relations with foreign nations, particularly with Hispanic American countries such as Colombia and Panamá. The establishment of such relations, however, requires permission from the U.S. Department of State or Congress itself. Still, most relations are already set by existent laws or trade agreements established beforehand by the United States that supersede the relation pursued by Puerto Rico.
