President Obama has welcomed Burma's president, Thein Sein, to the White House.
It is the first visit to Washington by a Burmese leader for almost 50 years.
Mr Obama praised Burma's recent political and economic reforms - but said that violence directed at Burma's Muslim communities needed to stop.
Relations with the West have been growing steadily warmer, since the regime ended military rule and brought in a number of reforms two years ago.
