Migration diplomacy provides the first systematic examination of the foreign policy importance of migrants, refugees and diasporas in the Global South. Tsourapas examines how emigration—related processes become embedded in governmental practices of establishing and maintaining power; how states engage with migrant and diasporic communities residing in the West; how oil—rich Arab monarchies have extended their support for a number of sending states’ ruling regimes via cooperation on labour migration; and, finally, how labour and forced migrants may serve as instruments of political leverage. Drawing on multi—sited fieldwork and employing a range of case—studies across the Middle East and North Africa, Tsourapas identifies how the management of cross—border mobility in the Middle East is not primarily dictated by legal, moral, or human rights considerations but driven by state actors' key concern – political power.
