The United States recognized the independence of Armenia, Azerbaijan, and Georgia when the former Soviet Union broke up at the end of 1991. The United States has fostered these states' ties with the West in part to end their dependence on Russia for trade, security, and other relations. The United States has pursued close ties with Armenia to encourage its democratization and because of concerns by Armenian Americans and others over its fate. Close ties with Georgia have evolved from U.S. contacts with its pro-Western leadership.
