Leaders of Japan and South Korea push for stronger cooperation at final summit

In South Korea, on September 29, 2025, influential leaders from Japan and South Korea convened for what was expected to be their concluding summit. This pivotal meeting took place in Busan and involved Japanese Prime Minister Shigeru Ishiba and South Korean President Lee Jae Myung. Both leaders highlighted the critical need for enhanced cooperation that encompasses economic, sociocultural, and security aspects, particularly against the backdrop of evolving global tensions, trade disputes, and North Korea's persistent nuclear ambitions. Lee expressed hope that their countries could develop a closer relationship, while Ishiba noted the importance of wrapping up his diplomatic tenure with this summit. The discussions also included mutual commitments to tackle pressing challenges such as low birth rates and disaster prevention strategies, as well as their shared goal of complete denuclearization on the Korean Peninsula. Environmental changes and a need to address agricultural dependencies also featured prominently in the agenda. Both leaders reaffirmed their resolve to establish a cooperative framework to facilitate ongoing dialogues and consultations on intertwined issues. Looking beyond the immediate successes of the summit, there is an acknowledgment that historical grievances could complicate the unfolding relationship, especially with the impending transition in Japan’s leadership following Ishiba's resignation due to recent electoral defeats. However, both leaders remain optimistic that this summit will lay the groundwork for a reimagined partnership as they collectively navigate the complex geopolitical landscape.
