A Guide to the United States' History of Recognition, Diplomatic, and Consular Relations, by Country, since 1776: Indonesia
U.S.-Indonesian interaction has a long history, dating back to the early 19th century when sufficient numbers of U.S. traders and others stopped in the then-Dutch colony to warrant the establishment of a consular post. However, relations remained on an informal level until after Indonesian independence following World War II.

The United States recognized the Republic of the United States of Indonesia on December 28, 1949, when U.S. Ambassador H.
