An ASEAN special envoy met with Myanmar's junta chief on Monday in the regional bloc's latest attempt to jumpstart dialogue between the military and opponents of its coup and bloody crackdown.

The Association of Southeast Asian Nations has led stalled diplomatic efforts to end the chaos unleashed by last year's putsch, which ousted Aung San Suu Kyi's government and sparked mass protests.

Cambodian Foreign Minister Prak Sokhonn and junta chief Min Aung Hlaing discussed "the situation of protests and violence stemming from political disagreement" and humanitarian cooperation, the junta's information team said in a statement.

The envoy's visit, which ends Wednesday, is aimed at "encouraging political consultations... with all parties concerned," according to an earlier statement from the Cambodian government that did not provide details.

The General Strike Coordinating Body (GSCB), a coalition of anti-regime forces, issued a statement on 21 March, strongly condemning the visit of Mr. Prak Sokhonn, the ASEAN Special Envoy for Myanmar, to Nay Pyi Taw.

The statement said that the ASEAN Special Envoy has failed to call for an end to the ongoing violence perpetrated by the military junta across Myanmar. The group also said that it would strongly oppose any international efforts to reinstate the military-drafted 2008 constitution.

Prak Sokhonn had previously requested to be allowed to meet with members of a "National Unity Government" dominated by lawmakers from Suu Kyi's ousted party that is working to overturn the coup.

The junta -- which has classified members of the shadow government as "terrorists" -- swiftly rebuffed the request.

Last year, the junta refused to grant ASEAN's then special envoy permission to visit Suu Kyi, who has been detained since the coup.

The bloc later barred Min Aung Hlaing from attending a leader's summit, a major snub from the body that has long been seen as a toothless talking shop.

Myanmar is increasingly isolated on the international stage, with Cambodian strongman ruler Hun Sen's January visit the first by any foreign leader since the generals seized power.

More than 1,600 people have been killed and over 12,000 arrested in a military crackdown since the coup, according to a local monitoring group.
