The ASEAN Ministerial Meeting on Minerals (AMMin), consisting of ASEAN Ministers responsible for minerals, is the highest policy making body  for ASEAN cooperation in the sector.  AMMin sets the policy directions and meets on a biennial basis.

The ASEAN Senior Officials Meeting on Minerals (ASOMM) is the main operating arm of the AMMin and oversees the working groups that assist the Senior Officials in the development and implementation of sectoral policies as well as the work programmes/plans under the four (4) AMCAP strategic areas.

Four (4) Working Groups focus on implementing the sector’s four strategic areas of cooperation.  These are the

• Working Group on Trade and Investments in Minerals (WGTIM)
• Working Group on Sustainable Minerals Development (WGSMD)
• Working Group on Capacity Building on Minerals (WGCBM)
• Working Group on Minerals Information and Database (WGMID)

A Joint ASOMM Working Groups Meeting (JWG) was also formalised in 2017 to facilitate discussion of all agenda items common to the WGs, and,  give opportunity for all Working Groups to interact on cross-cutting issues and on the progress of individual WG works/activities.
