U.S. states

With other countries

U.S. states are not sovereign in the Westphalian sense in international law which says that each State has sovereignty over its territory and domestic affairs, to the exclusion of all external powers, on the principle of non-interference in another State's domestic affairs, and that each State, no matter how large or small, is equal in international law. The 50 U.S. states do not possess international legal sovereignty, meaning that they are not recognized by other sovereign States such as, for example, France, Germany or the United Kingdom. The federal government is responsible for international relations, but state and local government leaders occasionally travel to other countries and form economic and cultural relationships.
