Myanmar's military government has criticized calls for the Association of Southeast Asian Nations' special envoy to the conflict-torn country to meet bodies that oppose last year's coup, which the junta has declared as "terrorist" groups.

With little sign of the junta implementing a five-point peace plan agreed upon with ASEAN last year, which included an immediate end to hostilities and letting a special envoy facilitate dialogue, growing divisions have emerged in the 10-member bloc over how to restore stability.

After last Thursday's ASEAN foreign ministers meeting, Indonesia said it was crucial for the envoy to meet all parties in the conflict, with Malaysia calling for talks with the National Unity Government (NUG), a group made up of members of the ousted administration and other junta opponents.
