The purpose of this legislation is to allow the U.S. Secretary of State to allocate funds for a United States pavilion or major exhibit at international expositions, also known as world's fairs. The goal is to enhance U.S. participation in these global events, which have historically showcased American culture, technology, and values while promoting diplomatic relations and cultural exchange. Key provisions of the legislation include the repeal of previous restrictions on federal funding for U.S. participation in international expositions.
