Joint Declaration on Denuclearisation and Search-and-Rescue Cooperation
On 28 June 2026, South Korean Defence Minister Ahn Gyu-back and Japanese Defence Minister Shinjiro Koizumi met in Seoul for the sixth round of bilateral talks. They reaffirmed a shared goal of a denuclearised Korean peninsula and agreed to restart joint humanitarian search-and-rescue (SAR) drills, the first such exercise in almost a decade.
Historical Background and Recent Diplomatic Momentum
Bilateral security ties have progressed since 2022 under U.S. encouragement, despite lingering grievances from Japan’s colonial rule of Korea. In 2019 Seoul ended the GSOMIA intelligence-sharing pact after Tokyo restricted semiconductor exports and removed South Korea from a preferential trade list. The 2025 agreement between then-Prime Minister Shigeru Ishiba and President Lee Jae Myung expanded security and economic cooperation, including coordination with Washington against North Korea’s nuclear programme and its growing ties to Russia.

Quantitative Highlights
Sixth round of defence ministerial talks. Joint SAR exercise scheduled for June 2026, described as the first in “almost a decade.” GSOMIA termination occurred in 2019.
Strategic Significance
The renewed commitment addresses the persistent nuclear threat posed by North Korea and reinforces a regional security architecture that includes AI and unmanned-system cooperation with Washington. Reviving SAR drills also enhances humanitarian response capacity in the maritime domain, a critical area for both nations.
Official Statements & Responses
South Korea’s defence ministry released a statement noting that both ministers “shared the view to continue cooperation for maintaining regional peace and stability amid a grave security environment.” Both governments emphasized the importance of bilateral coordination alongside Washington in confronting North Korean challenges.
Criticism & Opposition
Historical disputes persist. South Korea continues to protest Japan’s commemoration of the disputed islands known as Takeshima (Japan) or Dokdo (South Korea). Additionally, the legacy of Korean women forced into Japanese military brothels during World II remains a source of tension between the two societies.
