President Obama will become the first U.S. president to visit Burma and Cambodia when he travels to the Asian nations later this month.
The White House said Obama will also visit Thailand. The trip comes less than two weeks after Obama's re-election.
Obama's trip to Burma marks the culmination of a dramatic turnaround in the country's relations with Washington. Burma has shifted from five decades of ruinous military rule and shaken off the pariah status it had earned through its bloody suppression of democracy.
The president has suspended sanctions to reward Burma for political prisoner releases and other democratic reforms.
In Cambodia, Obama will attend the East Asia summit and meet with the leaders of the Association of Southeast Asian Nations.
