Cambodia said on Wednesday it had postponed a meeting of foreign ministers of the Association of Southeast Asian Nations (ASEAN) scheduled for next week, because some ministers had expressed "difficulties" in attending.

The meeting was the first under Cambodia's chairmanship of the 10-member bloc, which comes amid divisions on how to deal with the military that seized power in Myanmar last year and has led a bloody crackdown on thousands of its opponents.

Cambodian Prime Minister Hun Sen met Myanmar's military ruler Min Aung Hlaing last week, the first such visit by a head of government, sparking concern that it could undermine international efforts to isolate the junta.
