Internationalization of higher education pushes for more intensive regional collaborations as well as student mobility. There are a plethora of studies exploring student mobility patterns, but research on the transformative potential of regional mobility networks is limited. As the most predominant regional network of universities in Southeast Asia, ASEAN (Association of South East Asian Nations) University Network (AUN) commits to boosting student mobility in the region, and thus, can be conceived to be a deliberative space capable of expanding student mobility. This paper examines the role of AUN in promoting student mobility within the ASEAN region. Indonesia's engagement is used as a point of entry to assess the extent of policies and programs in encouraging student mobility in the ASEAN region.
