Myanmar's military chief Sen-Gen Min Aung Hlaing is not invited to an upcoming Association of Southeast Asian Nations (ASEAN) summit, the organization's current chair Brunei said on Saturday.

"As there had been insufficient progress... as well as concerns over Myanmar's commitment, in particular on establishing constructive dialogue among all concerned parties, some ASEAN Member States recommended that ASEAN give space to Myanmar to restore its internal affairs and return to normalcy," Brunei said in a statement.

Instead, a non-political representative from Myanmar will be invited to the gathering in late October, Brunei said.

The exclusion of Myanmar's army chief from the meeting is due to the failure of the country's ruling military to adhere to a peace roadmap it had agreed to with ASEAN, Reuters reported, citing sources.

A spokesperson for Myanmar's military government blamed "foreign intervention" for the decision, accusing the United States and representatives of the European Union of pressuring other ASEAN member states.

"The foreign interventions can also be seen here," spokesperson Zaw Min Tun said. "We learned that some envoys from some countries met with U.S. foreign affairs and received pressure from EU."
