The role of external actors in national health policy in aid-independent countries has received relatively little attention in the literature, despite the fact that influence continues to be exerted once financial support is curtailed as countries graduate from lower income status. Focusing on a specific health policy in an aid-independent country, this qualitative study explores the role of external actors in shaping Thailand’s migrant health insurance. Primary data were collected through in-depth interviews with eighteen key informants from September 2018 to January 2019. The data were analysed using thematic analysis, focusing on three channels of influence, financial resources, technical expertise and inter-sectoral leverage, and their effect on the different stages of the policy process. Given Thailand’s export orientation and the importance of reputational effects, inter-sectoral leverage, mainly through the US TIP Reports and the EU carding decision, emerged as a very powerful channel of influence on priority setting, as it indirectly affected the migrant health insurance through efforts aimed at dealing with problems of human trafficking in the context of labour migration, especially after the 2014 coup d'état. This study helps understand the changed role external actors can play in filling health system gaps in aid-independent countries.
