Refusing the proposal for six-party talks would be unlawful, Thura Shwe Mann, Union Parliament Speaker told the press in Nay Pyi Taw.
"Since the idea of six-party talks was approved by the Union Parliament. We should all pay attention to the results of the talks," he said.
The talks will probably be arranged during this parliamentary session.
Shwe Mann continued: "The Union Parliament is the highest legislative body in the country. The laws and proposals passed by it cannot be repealed by state and regional parliaments. I have no right to go against the will of Parliament as it would violate the law."
The Speaker said he had spoken to President Thein Sein about the talks.
The Parliament's proposal called for a meeting between the president, speakers from both houses, chairperson of National League for Democracy Aung San Suu Kyi, a representative of ethnic parliamentarians and commander-in-chief to streamline nation-building efforts.
Shwe Mann called on the president on January 22 to push for the six-party talks.
Meanwhile, Aung San Suu Kyi has said she was not interested in window-dressing talks and that she would continue demanding realistic meetings aimed at forging national reconciliation.
