The Tourism Promotion Organization (TPO) for Asian-Pacific Cities has been established by the initiatives of local level governments to encourage regional cooperation in tourism development and to adopt a regional approach to the promotion of the forty two cities from twelve countries in the Asia Pacific. It is however uncertain whether there is general consensus as to its necessity and applicability. This study examines the role and rationale of cooperative tourism promotion of the TPO's member cities. The tourism trends and prospects in the region are reviewed, the TPO's organizational structure and operation are outlined and its regional marketing objectives and strategy are suggested. It also defines how the TPO's members would benefit from regional cooperative efforts.
