Abstract
The extent of linkage between inter-Korean relations and North and South Korea's simultaneous membership in international organizations (including both inter-governmental organizations and non-governmental organizations) is examined. This research questions whether inter-Korean cooperation can be promoted and ultimately be attained via multilateral organizations. Empirical evidence shows three types and patterns of linkage: a) successful cases involving the inter-governmental organizations (IGOs), such as the UNDP, b) unsuccessful cases of engaging established UN specialized agencies, such as the UPU and the ITU, and c) cases with intermediary results, such as KEDO and the ICAO. Simultaneous membership in multilateral organizations does not automatically translate into promoting inter-Korean relations. Other contextual factors, like the international system structure, changing strategic environment, and the opportunity cost estimation by decision-makers, and likely to intervene. The paper discusses political problems and prospects for internationalizing North-South Korean relations and concludes by drawing certain implications for the mixed results of linkages between inter-Korean relations and multilateral organizations.
