This article analyzes “returnees from marriage migration” by focusing on Vietnamese women from Cần Thơ and Hai Phong who have been to South Korea for marriage migration. In contrast to prevalent concerns in South Korea about the possibility of “child abduction” by Vietnamese mothers/divorcees, the author found many “deserted” Korean Vietnamese children and their mothers in Vietnam through this research. There is also a growing number of Vietnamese “return marriage migrants,” women who came back to South Korea after their first divorce and return to Vietnam. The article emphasizes the complexities and multidirectional trajectories of marriage migration and highlights the agency of female migrants, whose contribution to family welfare and to “development” is often overshadowed by their status within the family.
