The chair and secretary-general of the Association of Southeast Asian Nations (ASEAN) plan to travel to Myanmar this week even as the 10-nation group remains divided on how to respond to the military coup there, four diplomatic sources told the Reuters news agency.

Myanmar is a member of ASEAN and has a policy of non-interference in the affairs of members, but it has led the main diplomatic effort to resolve the crisis that has engulfed the country since February 1 when the military staged a coup and removed the democratically elected government.

Erywan Yusof, the second minister for foreign affairs for Brunei, ASEAN’s chair this year and the group’s Secretary-General Lim Jock Hoi, also from Brunei, are scheduled to meet leaders of Myanmar’s military this week, the sources, who asked not to be identified, said.
