Men are disadvantaged in the marriage markets of many Asian countries, and in some cases their response is to look abroad for a partner. Receiving countries for marriage migrants include Japan, Korea, Taiwan, Hong Kong, and Singapore, while the Philippines, Thailand, Vietnam, Indonesia, and parts of mainland China supply wives to these territories. In the absence of uniform international regulations concerning the rights and obligations of partners, such unions are treated differently in different jurisdiction. In extreme cases migrants or their children become stateless, and when marriages break down, migrants sometimes face major legal problems. In such circumstances, marriage migrants are often portrayed as powerless, uneducated victims. Rejecting this perspective, the authors in this volume explore the agency of women who migrate abroad to acquire opportunities unavailable to them in their homelands. They show that the trajectories of marriage migrants are often not a simple movement from home to destination but can involve return, repeated, or extended migrations, and that these transitions that can alter geographies of power in economics, nationality or ethnicity. Based on features shared by many marriage migrants, the book identifies them as an emerging minority at the frontier of the nation-state, a group whose status may well carry over to future generations.
