Singapore's Prime Minister Lee Hsin Loong arrived in Burma Wednesday as part of a three-nation tour of southeast Asia.
Mr. Lee and his foreign minister, George Yeo, were scheduled to meet with Burmese military leaders during their visit, including junta leader Senior General Than Shwe and Prime Minister Lieutenant General Soe Win.
Mr. Lee's trip is taking place as criticism mounts within southeast Asia over the slow pace of democratic reforms in Burma.
Lawmakers in Malaysia and the Philippines are considering resolutions that would deny Burma its scheduled chairmanship of the 10-member Association of Southeast Asian Nations (ASEAN) in 2006.
Mr. Lee visited Laos on Tuesday. He travels to Cambodia Thursday for talks with Prime Minister Hun Sen and King Norodom Sihamoni.
