Standing Committee for Southeast Asia (DELGOSEA) was established to support the implementation of DELGOSEA that aims to promote stronger partnerships among cities and local governments in South-East Asian sub-region.

The Standing Committee has gathered in Manila in April 2015 to discuss the new structure of the Network, and to propose the template of the monitoring and evaluation of the activities. Another meeting was held in conjunction with the ASEAN Mayors Forum in Makassar in September 2015 in which the Work Plan of 2016 was presented and the composition of the National Steering Council was formed.

To continue advocating to ASEAN, as part of the objective of DELGOSEA, UCLG ASPAC in cooperation with Makassar, the Ministries of Home Affairs and Foreign Affairs of Indonesia, and UNDP had successfully organized the ASEAN Mayor Forum 2015. A publication of South-South Cooperation on Replicable Best Practices was compiled to give insight in the dynamics of local government developments. It was distributed in Makassar.
