SEOUL, June 28 — Japan and South Korea have agreed to deepen their cooperation on artificial intelligence in the defense domain, a move that carries clear implications for how regional powers are thinking about the next generation of military technology.
The agreement came out of a meeting between Japanese Defense Minister Koizumi and his South Korean counterpart, Ahn Gyu-back, in Seoul on the morning of June 28. According to a statement from the Japanese Defense Ministry, the two ministers confirmed a policy of further developing cooperation in AI, building on what they described as productive discussions between defense authorities in the field.
For India, which has its own growing defense tech relationship with Japan and watches the Korea-Japan axis closely, this signals that AI is no longer a niche experimental area in Asian military cooperation — it is becoming a formal pillar of bilateral security dialogue.
The ministers also welcomed the June 7 joint search and rescue exercise between the Maritime Self-Defense Force and the South Korean Navy. That drill, the first of its kind in roughly nine years, marked a tangible step in restoring operational trust between the two navies.
Beyond the bilateral track, the ministers agreed to continue trilateral cooperation among Japan, South Korea and the United States. This three-way framework has been a consistent priority for Washington, and the latest affirmation suggests it remains on track despite the usual diplomatic friction between Tokyo and Seoul.
On a separate track, the two sides confirmed plans to expand exchanges following a visit by the South Korean Air Force aerobatic team, the Black Eagles, to Naha Air Base in Okinawa Prefecture in January 2026.
One notable silence in the discussions: a Defense Ministry official declined to comment on whether the ministers discussed an Acquisition and Cross-Servicing Agreement, or ACSA. Such an agreement would allow the two countries to smoothly provide each other with fuel and other supplies during operations — a logistical enabler that analysts say would mark a significant deepening of the bilateral defense relationship.
For Asian markets watching the defense technology space, the AI angle is the headline. Japan and South Korea are both major producers of semiconductors and advanced electronics, and their defense establishments are increasingly looking to integrate AI into surveillance, logistics and decision-making systems. A formalized cooperation framework in this area could create new opportunities for joint development and procurement.
What to watch next: whether the two sides move toward a formal ACSA, and whether the AI cooperation yields specific joint projects or remains at the level of working-level discussions.
