Abstract: The 1974 joint development agreement between Korea and Japanestablished an innovative cooperation regime in the East China Sea.According to the agreement, Korea is obligated to conduct jointlywith Japan in the defined zone, but Japan holds a negative stance onthe potential reservation, leading to a deadlock on commercial activi-ties. The reasons for the stalemate are, on the one hand, due to alack of motivation because no commercial products pay back, and onthe other because the mechanism of the agreement does not envisagea straightforward solution to thepredicament. Compared with the1970s, the incompatible legal positions on the maritime boundariesand vexed political geographical relations between the coastal Statesmake the Joint Development Zone more controversial. This studyidentifies alternative approaches based on thorough analyses ofpolitical and legal factors such as joint development regime, evolvingrules of international law, bilateral cooperation, and regionalrelations.
