As of 2020 February, the APGN had 60 institutional members (UNESCO Global Geoparks) in countries.

The APGN was founded in 2007 based on the proposal at the 1st Asia Pacific Geoparks Symposium in Langkawi (Malaysia).

It was endorsed by GGN in 2008 and became its official regional geopark network in 2013, in compliance with its Rules of Operation.

As a regional geopark network, APGN is the organizer of several workshops and seminars, capacity building activities, common projects, promotional activities, and common publications between the member countries and UNESCO Global Geoparks.

Besides the regular meetings of the Advisor and Coordination Committees, the most important events of the network are the biennial symposiums, a place of exchange on research activities and management practices in geoparks.
