United Nations envoy Ibrahim Gambari is in Asia on a tour aimed at gathering support for political reconciliation in Burma.
Gambari arrived in Bangkok late Sunday, on the first stop in a series of meetings with officials in Thailand, Malaysia, Indonesia, India, China and Japan.
Gambari has said that after those visits, he hopes to return to Burma, where he met last month with the country's top military leader, Than Shwe, and detained democracy leader Aung San Suu Kyi.
U.S. Secretary of State Condoleezza Rice has urged Gambari to return to Burma as soon as possible. She said Sunday there is a clear need for an international presence there.
Human rights group Amnesty International said Burmese authorities detained at least four more prominent pro-democracy leaders Saturday.
The group says the government has rounded up thousands of activists and Buddhist monks since last month's deadly crackdown on pro-democracy rallies.
However, Burma's military government has relaxed a curfew and restored Internet access for the first time since the crackdown began. Residents in Rangoon said the curfew has been reduced from six hours to four hours a night. Internet users say Web access was restored Saturday.
The government cut Internet service last month to stop the transmission of footage out of the country showing the military's violent response to mass anti-government demonstrations.
