President Yoon Suk-yeol and Prime Minister Kishida Fumio’s March 2023 summit was intended to help South Korea-Japan relations turn the corner from a rocky period of historical disagreements to a smoother path for functional cooperation.  What were the accomplishments of the summit?  Where are bilateral relations still falling short of their potential?  How can the two governments (and societies) solidify recent gains and further economic and security policy coordination in the national interests?  This presentation builds on recent research about Seoul and Tokyo’s mechanisms for stabilizing ties — political restraint, pragmatism toward China, and trilateralism with Washington — and the importance of realizing support from civil society.
