Migration diplomacy
In international relations, migration diplomacy is 'the use of diplomatic tools, processes, and procedures to manage cross-border population mobility,' including 'both the strategic use of migration flows as a means to obtain other aims, and the use of diplomatic methods to achieve goals related to migration.' Migration has come to constitute an increasingly-important area of states' engagement with one another, with bilateral multilateral strategies including the promotion or discouragement of bilateral migratory flows; agreements on preferential treatment to certain foreign nationals; the initiation of guest-worker programmes or other short-term labor migration schemes; the deportation of foreign nationals; and so on. == Background == For political scientist James F. Hollifield, the latter half of the twentieth century gave rise to the migration state, which followed the garrison state of the eighteen and nineteenth centuries, and the trading state of the nineteenth and twentieth centuries: whereas, in the past, a central component of states' functions related to their ability to engage in war or to manage trade, the contemporary state is defined by the management of cross-border population mobility.
