The 21 nation member APEC provides a forum for ministerial level discussion and cooperation on a range of economic issues including trade, investment, technology transfer, and transportation. According to APEC, a key feature that sets it apart from other international organisations is its commitment to business facilitation and the regular involvement of the private sector in a wide range of APEC activities.
