Southeast Asian nations have issued their strongest rebuke ever to military-ruled Myanmar over its democracy record. The criticism came at an annual security meeting of the foreign ministers from the 10 countries that form the Association of Southeast Asia Nations. The meeting formally opened Monday amid a bubbling border conflict between Thailand and Cambodia. At the end of a working dinner Sunday, the ministers issued a statement expressing "deep disappointment" that Myanmar's junta had extended the detention of pro-democracy leader Aung San Suu Kyi by another year. However, Myanmar Foreign Minister Nyan Win held out a glimmer of hope that Suu Kyi would be freed within six months at the end of the maximum six-year period that a political detainee can be held by law.
