Myanmar's opposition party led by Aung San Suu Kyi said on Wednesday there should be no pre-conditions for the United States starting a dialogue with the ruling junta.
The US announced on Monday it was starting a dialogue with the military-led nation, although it insisted it would keep sanctions in place until the regime makes progress on democracy.
"Starting a dialogue between two countries is good. Daw Suu has said so," said Nyan Win, a spokesman for the National League for Democracy (NLD). Daw is a term of respect in Myanmar.
"It will be the best if there are no pre-conditions in a dialogue," he said.
The US State Department said on Tuesday that a senior US diplomatic official was set to meet with a delegation from Myanmar on the margins of the UN General Assembly meeting in New York.
State Department spokesman Philip Crowley told a Washington press briefing that Kurt Campbell, assistant US secretary of state for Asia, would meet with a delegation headed by Myanmar's science and technology minister U Thaung.
Myanmar's representative to the United Nations, Than Swe, was also expected to participate.
The Obama administration's decision to reengage with Myanmar comes after years of stalemate proved unproductive.
