Seoul Meeting Sets Agenda for Expanded Defense Ties
On June 28, 2026, South Korean Defense Minister Ahn Gyu-back hosted Japanese Defense Minister Shinjiro Koizumi at the Ministry of National Defense in Yongsan, Seoul. Koizumi’s visit was his first as Japan’s defense minister and reciprocated Ahn’s January trip to Tokyo. The agenda featured a joint press conference, a tour of the Black Eagles aerobatic unit in Gangwon Province, and a discussion with youth at the Korea Institute for Defense Analysis.
Historical Context and Resumption of SAREX
Historical grievances, especially Japan’s colonial rule of Korea (1910-45) and a 2018 low-altitude flyby dispute, have constrained military exchanges. After a nine-year pause, the navies resumed joint maritime search-and-rescue (SAREX) drills in early June, following a JMSDF-ROKN exercise west of Japan’s Goto Islands. A December call resolved a 2025 refueling dispute over the Black Eagles, allowing refueling at a Japanese base in February.
Agreements Reached
The joint statement listed four actions: expand Black Eagles–Blue Impulse aerobatic exchanges; develop SAREX training for varied maritime scenarios; pursue advanced science and technology cooperation, explicitly naming artificial intelligence (AI); and reaffirm commitment to the complete denuclearization of the Korean Peninsula and regional peace. Ministers pledged continued bilateral coordination and trilateral cooperation with the United States. The long-sought Acquisition and Cross-Servicing Agreement (ACSA) was not on the agenda.
Sensitivities and AI Outlook
South Korean observers note that military cooperation with Japan remains politically sensitive because of the colonial legacy, prompting a focus on non-combat activities such as aerobatic exchanges and rescue drills. The AI provision is aspirational; no budgets, programs, or milestones were announced, but analysts expect it to launch technical working groups and joint testing frameworks for maritime domain awareness, sensor fusion and SAR automation.
