It has been widely argued that Area Studies is in a critical condition especially in Australia, Europe and the US. However, in the Southeast Asian region, most especially Indonesia, we are witnessing the rise of Area Studies programs with the establishment of several such programs both in research institutions and universities. In this paper, I will discuss a few examples of Area Studies research on the emerging diasporic connections in Southeast Asia and reflect on the constitution of ethnic networks as “sites” where transnational identities are forged beyond state boundaries. Indeed, transnational movements of people have occurred and continue to happen due to particular events like wars and political turmoil, as well as for economic reasons. Today, we find many diasporic groups, including minorities, in the border areas of Southeast Asian countries and historically, minorities have been known for their movements in mainland Southeast Asia. If previously, the diasporic connections, especially with the homeland, had been very limited or even non-existent, today such connections have emerged across national boundaries. On top of this, economic and social networkings are equally on the rise both within and at transnational levels. It is, therefore, important to discuss the identity of diasporic groups and transnational networkings in the cases of two border areas in Southeast Asia.
