South Korea, United States and Japan to Cooperate on Northern Sea Route and Energy Development... Stepping Up Efforts to Counter China and Russia

[Financial News | Tokyo—Special Correspondent Seo Hye-jin] South Korea, the United States and Japan are joining forces to develop the Northern Sea Route (NSR) and Arctic energy resources. The initiative is aimed at countering China and Russia, which are expanding their influence in the Arctic, while establishing new logistics and energy supply chains.
According to The Yomiuri Shimbun on the 20th, South Korea, the United States and Japan are pursuing the signing of an MOU on maritime cooperation in the Arctic and expanded energy supplies. Foreign Minister Cho Hyun, U.S. Secretary of State Marco Rubio and Japanese Foreign Minister Toshimitsu Motegi are expected to meet and sign it in New York on the occasion of the UN General Assembly.
The draft MOU states that cooperation in the Arctic is essential to the economic security of the three countries. They plan to establish a working group, tentatively named the "Trilateral Arctic-Pacific Partnership," to discuss specific cooperation measures. They also plan to coordinate with the Arctic Council, which consists of eight Arctic states, including Denmark and Norway.
The cooperation will focus on two pillars: maritime affairs and the economy. In the maritime sector, Japan will share icebreaker-construction technology and ocean-observation capabilities it has accumulated through vessels such as the Antarctic observation ship Shirase. The three countries are also expected to discuss ways to respond jointly to accidents or disasters in the Arctic Ocean.
In the economic sector, the three countries will consult on expanding the production and supply of oil and natural gas, which are abundant in the Arctic region. Japan plans to begin operating the Mirai II Arctic research vessel this year to collect information needed for ocean and weather observation and safe navigation. Based on this information, it aims to gain a stronger voice in discussions on the use of the Arctic Ocean and the development of international rules.
The United States is wary of Russia's military activities and China's advance in the Arctic region bordering Alaska. The United States Department of Defense (DoD) identified expanding China-Russia cooperation as a security threat in its Arctic strategy released in 2024. This is why Washington seeks to involve its allies, South Korea and Japan, to strengthen surveillance and navigation capabilities.
South Korea is pursuing plans to use the NSR as a new logistics network connecting it with Europe. If the NSR becomes fully operational, it is expected to reduce voyage distance and duration by approximately 30% each, compared with existing routes through the Suez Canal.
As receding sea ice in the Arctic Ocean expands the possibilities for shipping and resource development, the Arctic region is emerging as a new arena for economic and security competition. Cooperation among South Korea, the United States and Japan is also expanding beyond traditional military and security matters to include shipping routes, energy and supply chains.
