Representatives (Mayor or Governor) from member cities gathered to convene a plenary meeting once a year.
At the meeting, in addition to reports on the progress and outcome of joint projects, comprehensive discussions on urgent issues of common concern were conducted as "Policy Dialogue," and reports of specific measures on such issues as "Special Report." Important administrative matters were decided and a joint declaration was also adopted at the meeting.
For the smooth operation and administration of the network including preparations for the plenary meeting, working-level officials of ANMC21 member cities also convened to hold “working-level meetings” for discussion and coordination.
