The main purpose of this legislation is to create an Office of Subnational Diplomacy within the U.S. Department of State. This office aims to enhance the ability of local and regional governments—such as state, county, city, and municipal governments—to engage in international relations. The goal is to help these governments attract foreign investment, counter foreign influence, and align their actions with U.S. foreign policy priorities. Key provisions of the legislation include the establishment of the Office of Subnational Diplomacy, which will be led by a Special Representative.
