"Chile has maintained friendly relations with the United States since its transition back to civilian democratic rule in 1990. The Obama Administration has sought to build on these traditionally close ties and encourage Chile's leadership in the Western Hemisphere. Bilateral commercial relations are particularly strong; total trade in goods and services has nearly tripled since the implementation of a free trade agreement in 2004. Additional areas of cooperation include supporting regional stability and promoting clean energy development."
