The past decade has seen the rapid development of transnationalism research, but transnationalism from below in situations of mass refugee influx has received little attention. However, the case study of Burmese refugees in Thailand clearly demonstrates that those refugees can maintain economic, social, cultural and political links with co‐nationals in all the domains of the refugee diaspora, even if their capabilities are in principle strained. It is argued here that the legal status of the person or diaspora organization concerned, as well as the country of origin and the host country have a larger influence on the type of transnationalism than the label ‘migrant’ or ‘refugee’. The concept of transnationalism should thus be conceived in a more encompassing sense, both geographically, thematically and including all emigrants regardless of their original motivations for migration. The article is based on fieldwork, including over 150 interviews with Burmese refugees and political activists.
