ASEAN, long derided as a toothless talking shop that gives political cover to repressive regimes, has spearheaded so far fruitless efforts to restore peace.
The bloc last week condemned the military’s execution of four prisoners, with some member states growing frustrated at the lack of progress.
The five-point plan calls for an immediate end to violence and dialogue between the junta and coup opponents.
But after more than a year without progress, Malaysia has said it would present a framework for its implementation.
Myanmar itself will not be represented at the meeting after the other members said they would not accept a junta minister and the generals refused to send another official instead.
Some member states, led by Malaysia and the Philippines, are pushing to bar the military regime from sending ministers to any ASEAN meetings -- including November’s summit -- until there is progress on the five-point plan.
