About 77 Thai lawmakers are calling on their government to oppose Burma's chairmanship of the Association of Southeast Asian Nations in 2006.
The petition filed with the Thai Senate Monday is similar to other resolutions introduced by lawmakers in the Philippines and Malaysia opposing Rangoon's assumption of the rotating chairmanship of the 10-nation regional bloc.
The United States and the European Union have threatened to boycott ASEAN high-level meetings if Burma takes over the leadership.
Burma's military rulers are under increased international pressure to implement democratic reforms and release all political prisoners, including pro-democracy leader Aung San Suu Kyi.
Thailand says it is working on a compromise among the 10 ASEAN members to break a deadlock over the issue.
