APT Conference Preparatory Group for WRC-27 (APG-27)


The APT Conference Preparatory Group for World Radiocommunication Conference (APG) has been developed into one of the most important activities of APT. APG was started in 1996 with the objective of harmonizing views and developing common proposals from the Asia-Pacific region for the World Radio Conference (WRC). The APG process has met exemplary success in presenting the views of the region at WRCs. As a result, APG becomes the one with highest attendance from the members in the region. It has substantially helped establishing the prominence given to APT amongst other regional and international organizations.


The main objective of APG is to organize coordinated regional activities for WRCs and RAs in order to ensure that the interests of APT Members on Radiocommunication issues are properly represented. The activities include but are not limited to:

  • develop APT Common Proposals (herein after referred to as “ACPs”) for WRCs and on matters related to ITU Radiocommunication Assemblies (RAs);
  • develop APT contributions to ITU-R Conference Preparatory Meetings (CPMs); and
  • assist APT Member countries, especially developing countries, in their preparations for WRCs, RAs and CPMs.
