Why is there so little migrant settlement in East Asia?

Unlike states in Europe, East Asia settles very few migrants and has not developed a European-style multicultural society. We seek to explain this variation using comparative analysis of two of the most advanced states in East Asia, South Korea and Japan, with several states in Europe. Focusing on family reunification - almost always the precursor to migrant settlement - we examine the effects of several independent variables, including supranational institutions, independent courts, interest groups, political culture, and the perceptions of migrants. We conclude that both Korea and Japan have less migrant settlement because of the lack of regional institutions pushing for family reunification rights, an elite political culture that still maintains the assumptions and repertoires of a "developmental state," where rights may be sacrificed for economic growth and order, and migrant perceptions of greater immigration control in Asia.
