A significant number of tourists in most Southeast Asian economies are comprised by regional visitors. Among the first six members of ASEAN, the Philippines appeared to be the only member country receiving relatively lower arrivals of regional tourists. This characteristic is obviously the result of deficiency in infrastructures to facilitate tourists as well as the lack of precise security needed for tourism development. The potential significance of regional tourism for the Southeast Asian economies was acknowledged soon after the formation of ASEAN. In the charter of ASEAN, regional tourism collaboration was given a particular place in an attempt to establish regional peace and progress. Although trade and economic development were the main targeted areas of Southeast Asian regional cooperation, tourism has recognized as an important tool to foster these activities. Nevertheless, until 1990s regional tourism received only insignificant importance for the Southeast Asian economies (Ghimire, 2001). During 1990s, the share of regional tourism within Southeast Asian boarders was found to be somewhat low as most of the international tourists’ arrivals had their transit through Thailand and Singapore. However, the scenario had started reshaping since the beginning of 2000. The emergence of low-cost carrier is also playing an important role to this regional growth of tourists’ arrival. Given the evolving change, regional tourism has the potential, to a greater extent, for increased investment. This will certainly assist in generating income and employment for diverse segments of population. The importance should be given to intra-regional tourism development in that the economic benefits of regional tourism remain within the region. To ensure this, there is a need to undertake some initiatives as most of the initiatives to boost the regional tourism remain hypothetical. A repeated method of policy monitoring along with the critical evaluation of policy are to be devised in order to upgrade the current regional tourism strategies. This is analogous to the study of Ghimire (2001) in which the author mentioned that most of the activities remain either exhausted or stuck at the level of a declaration of good intentions and elaboration of policy strategies.
