Yangon  - Myanmar Prime Minister Thein Sein left for New York on Saturday afternoon to attend the 64th session of United Nations General Assembly, an official source confirmed.

"Prime Minister General Thein Sein left from Nay Pyi Taw via Yangon international airport on Saturday afternoon. He will be heading to New York via Bangkok," an official who requested anonymity said.

Thein Sein is scheduled to speak the general assembly. He is accompanied by Science and Technology Minister U Thaung and some senior officials from Ministry of Foreign Affair, the source said.

The prime minister would be the highest-ranking official to attend a UN General Assembly since Maung Aye, currently vice senior general, attended the 50th anniversary special commemorative session in 1995.

Political sources in Yangon said Thein Sein was likely to outline the ruling junta's plan to introduce limited political reform in his speech to the assembly. (dpa)
