The Association of South East Asian Nations (ASEAN) is a regional economic grouping that is composed of Brunei, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam. An ASEAN-wide logistics development policy has been developed and endorsed by ASEAN in August 2007. This logistics development policy is based on the work done by the authors as requested by the ASEAN Secretariat. The authors provided the guiding principles, the six major policy areas as well as the draft of the logistics sector integration roadmap that was finalised and endorsed by ASEAN. It is hoped that the formal endorsement of this important sector for ASEAN economic integration will support logistics liberalisation and development within ASEAN. The purpose of this paper is to explain the methodology utilised in the formulation of the ASEAN logistics development policy that was endorsed by ASEAN member countries.
