The Association of Southeast Asian Nations has asked China for help in its efforts to defuse the situation in Myanmar.
The foreign ministers of the ASEAN member countries and China met in the inland Chinese city of Chongqing on Monday.
Wunna Maung Lwin, the foreign minister appointed by Myanmar's military following the coup, also took part.
Indonesia's foreign ministry said they discussed a five-point consensus agreed on at the ASEAN summit in April.
The agreement calls for an immediate halt to violence in Myanmar and an envoy to be sent to mediate talks between the military and the pro-democracy camp, among other steps.
Indonesian Foreign Minister Retno Marsudi later told reporters that it is ASEAN's duty to implement the agreement immediately.
A Chinese foreign ministry spokesperson said Beijing will maintain close communication with ASEAN and support its mediation efforts in order to secure an "early soft landing" for the situation in Myanmar.
But a path to implementation of the five-point agreement remains uncertain, as Myanmar's military continues with its crackdown on citizens. The military has said it will consider accepting such an envoy, once the situation settles down.
