ABSTRAKThe internationalization of higher education over the last two decades has transformed the education sector into a globalized, interconnected knowledge based society. Higher education institutions and national governments have been compelled to pay more attention to academic relations and knowledge exchange opportunities with partners in other countries, particularly in the same region. The current study aims to investigate the role of higher education internationalization in Southeast Asian nations ASEAN for the development of a more harmonized region. Previous research has revealed that less developed countries in the ASEAN region are far behind in the race to globalization and transformation of the education industry. Therefore, it is crucial to explore the policies and strategies enacted by the ASEAN administration and determine what it lacks to achieve this goal. An exploratory comparative approach has been used to identify and investigate recent internationalization trends in ASEAN member countries. The internationalization of higher education is a compelling and logical approach to increasing harmonization at the intra regional and interregional levels.
