Burma's President Thein Sein is due to address the UN General Assembly after the United States announced that it was lifting its ban on the import of goods from Burma.
The opposition party led by Aung San Suu Kyi welcomed the lifting of the ban.
The BBC's Jonathan Head has been talking to the speaker of the Burmese parliament, Shwe Mann, one of the top generals in the old regime, who said that the "Burmese reform reform process is irreversible".
