Friendly relations between the United States and Brunei date to the 1800s. By 1865, the United States had a consular presence in Brunei. The U.S. maintained diplomatic relations with the Sultan of Brunei’s government until it became a British protectorate in 1888, at which time the United Kingdom assumed responsibility for Bruneian foreign affairs. Brunei reacquired its full independence in 1984.
