Relocation of U.S. military bases in Korea is in the final stage. This study aims to identify major issues during the relocation, analyze the causal relationship, and track the progress to draw implications in the process of resolving the issues. As a result, it was noted that the issues in terms of alternative facility requirement, cost sharing, in-kind provision, and moving service were eventually resolved through reasonable efforts by two countries. Although SOFA Joint Committee resolved differences in general, the agenda was treated by the diplomatic and security channels if necessary. In this process, Korea and the U.S. consented a considerable number of principles and standards, which can be referred to for future relocation of U.S. military facilities in Korea. The study suggests that both Korea and the U.S. should make a co-operative effort for the further development of the RoK-US alliance when pursuing the relocation of U.S. military facilities in Korea.
