Sweden, NATO and the role of diasporas in foreign policy

Abstract When and how do diasporas influence the foreign policy of liberal democratic states? Few studies have sought to conceptualize how diasporas affect strategic bilateral relations between states. We argue that these non-state actors are an increasingly important factor in western liberal democratic societies, which challenge traditional theories of foreign policy. To explore when and how the transnational societal ties and interests of diaspora groups affect foreign and security relations between states, we develop a triadic analytical model of state–diaspora interactions and specify key contextual factors. To illustrate the dynamics at play, we analyse the influence of the Kurdish diaspora in Sweden on Turkish–Swedish bilateral relations in the wake of Sweden's decision to apply for full NATO membership. Our case-study builds on semi-structured interviews as well as news media sources, speeches and official documents. The study shows that the Kurdish diaspora demonstrates an independent role and an ability to shape the policy process due to the permeability of the political system. As a result, the policy-process is becoming more domesticated, thereby constraining the role of the executive. The article contributes important insights to policy-makers and diplomats on what impact transnational state–society relations can have on foreign policymaking.
