Slovenia–United States relations
The United States has maintained an official presence in Slovenia since the early 1970s, when the United States Information Agency (USIS) opened a library and American press and cultural center in Ljubljana. From its opening through 1992, the American Center worked to develop closer grassroots relations between the United States and the people of the then-Socialist Republic of Slovenia, a constituent republic of the Socialist Federal Republic of Yugoslavia.
