The United States, Japan and South Korea signed a memorandum on Friday on cooperation in the Arctic region and the northern Pacific. The agreement was signed during a meeting of their foreign ministers in Atlanta.
The three countries have named their new grouping the Trilateral Arctic Pacific Partnership. According to Japan’s Ministry of Foreign Affairs, the memorandum is intended to enable cooperation on maritime security, emergency assistance and economic activities in the Arctic and the adjacent Pacific.
The document was signed by US Secretary of State Marco Rubio, Japanese minister Toshimitsu Motegi and South Korean Foreign Minister Cho Hyun. The meeting took place on the sidelines of the G20 foreign ministers’ meeting in Atlanta.
The agreement is not a military treaty and contains no automatic obligation to defend one another in the event of an attack. The countries refer to further exploration of cooperation. According to a report by The Korea Herald, this will also involve a working group; concrete projects and responsibilities still have to be worked out.
The step brings together three countries that already cooperate closely on security in East Asia, partly because of the military threat from North Korea. With the new agreement, they are extending that cooperation to an area that is becoming more important for shipping, raw materials, research and strategic links.
For Europe, the maritime dimension is particularly relevant. The Arctic is changing as a result of climate change and is consequently becoming more accessible to shipping and economic activities, while strategic rivalry between major powers is also increasing. The new memorandum in itself says nothing about specific routes, investments or military presence.
The practical significance of the agreement will depend on how it is developed. Further implementation could raise questions about the services and companies involved, information-sharing and the relationship with existing institutions, including the Arctic Council. For now, it is a political framework, not a fully developed programme.

One story, several perspectives
What is established
- The United States, Japan and South Korea signed a memorandum on 30 October 2026 on cooperation in the Arctic region.
- The areas mentioned include maritime security, emergency assistance and economic cooperation.
- The memorandum does not yet set out concrete projects or defence obligations.
Left
Arguments Cooperation in the Arctic should focus primarily on rescue operations, scientific research and environmental protection, rather than further militarisation or a race for raw materials.
Values International rule of law, climate responsibility and peaceful cooperation.
Consequences A security-focused approach could increase tensions and place further pressure on vulnerable ecosystems.
Centre
Arguments Practical cooperation is sensible as long as it remains transparent and aligns with existing international institutions. Security, shipping and emergency assistance cannot be considered separately.
Values Stability, multilateralism and administrative oversight.
Consequences A clear framework can prevent incidents, but its added value will depend on concrete agreements and cooperation with other Arctic countries.
Right
Arguments The growing strategic importance of the Arctic calls for stronger deterrence and reliable partnerships. Democratic countries must prevent rivals from dominating the region.
Values National security, alliance solidarity and economic resilience.
Consequences More cooperation could strengthen the partners’ position, but could also create a security dilemma and lead to higher defence and infrastructure spending.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.
