President Lee Jae-myung Meets Taro Aso: Restoring South Korea-Japan Shuttle Diplomacy (2026)

Two neighbors sharing a front yard are finally finding common ground. On January 16, 2026, President Lee Jae-myung met with former Japanese Prime Minister Taro Aso in Seoul to solidify the recent warming of bilateral ties. This meeting follows a high-profile summit in Nara, Japan, signaling that shuttle diplomacy is once again a cornerstone of East Asian geopolitics.

South Korea Japan Shuttle Diplomacy and the Lee-Aso Dialogue

According to Yonhap News, President Lee emphasized that South Korea and Japan must seek mutually beneficial relations by expanding cooperation across multiple sectors. This visit marks Lee's fifth summit-level interaction with a Japanese leader since taking office in June 2025. The rapid frequency of these meetings—including a summit in Nara earlier this week with PM Sanae Takaichi—suggests a significant shift toward a more stable diplomatic architecture.

Strategic Alignment Amid Regional Tensions

The diplomatic push comes at a critical time as tensions between Beijing and Tokyo remain elevated. Both leaders agreed to advance 'future-oriented cooperation' through reciprocal visits. Taro Aso noted that holding two summits in less than three months is highly meaningful given the changing international situation. Key topics of interest include South Korea's bid for the CPTPP and joint efforts to address historical grievances, such as the remains of Korean forced laborers.
