After four and a half years of interruption, Japan, China, and South Korea finally held their trilateral summit. Initiated in 2008 and planned to be held annually, the summit has promoted three-way economic, trade, and cross-sectoral cooperation. Over the years, historical grievances, territorial disputes, and strategic divergencies between the three neighbours often derailed mutual engagement, thus disrupting the trilateral framework.
In 2024, the timing was ripe for the leaders to meet again. The 9th summit has succeeded in restoring communication among Japan, China, and the ROK and in softening somewhat the rough edges of the trilateral framework. This approach reflects the shared understanding in Tokyo, Beijing, and Seoul that common challenges and goals, including ageing societies and enhanced connectivity of supply chains, require joint responses. As the other regional players in the wider Indo-Pacific, especially the smaller Southeast Asian nations, navigate an increasingly unpredictable strategic environment driven by major power rivalries, the restoration of dialogue among the three Northeast Asian heavyweights sends a positive signal to the whole region.
The summit did not lead to major breakthroughs on sensitive matters. Future cooperation between Japan, China and South Korea will likely remain limited to the economic and non-traditional security domains, not crossing over to the more sensitive geopolitical, territorial, and national security issues. At the same time, taking into consideration the continuing divisions over security issues, the strategic significance of restored high-level dialogue among three highly interdependent economies and key geopolitical players in the Indo-Pacific region should not be underestimated.
