The ministers also signed a memorandum to launch a Trilateral Arctic Pacific Partnership, opening maritime and economic collaboration pathways.
South Korea’s foreign minister, the United States secretary of state, and Japan’s foreign minister met on the sidelines of the Group of 20 meeting in Atlanta on Friday, October 30 2026, emphasizing a shared pledge to pursue the complete denuclearization of the Korean peninsula. The three leaders, Cho Hyun, Marco Rubio, and Toshimitsu Motegi, confirmed that their nations would “reaffirm their resolute commitment to the complete denuclearization” of North Korea, as stated by the U.S. State Department in a readout of the session.
The meeting focused on the enforcement of U.N. Security Council resolutions that prohibit activities generating revenue for Pyongyang’s nuclear and ballistic missile programs. Officials praised the work of the Multilateral Sanctions Monitoring Team for exposing North Korea’s sanctions violations and noted the need for sustained pressure. They also highlighted concerns over China’s actions in the South China Sea, East China Sea, and Yellow Sea, and the growing cooperation between Russia and China, which Washington says erodes peace and stability in the Indo‑Pacific. In the broader context of regional security, the ministers embraced a robust deterrence posture while pursuing dialogue and diplomacy, affirming that peace on the peninsula must come through sustained engagement.
In addition to the diplomatic reaffirmation, the three foreign ministers signed a memorandum of cooperation that establishes the Trilateral Arctic Pacific Partnership. The partnership is aimed at exploring maritime and economic collaboration across the Pacific and Arctic regions. “TAPP will open new pathways for cooperation in the maritime domain, while strengthening our joint economic interests,” said a statement from the ministries. The signing comes as the three countries coordinate their strategies to keep the Taiwan Strait stable, a critical maritime corridor between East Asia and the world.
The trilateral discussion also highlighted the role of South Korea as a “pacemaker” in the ongoing effort to establish a peace regime on the Korean Peninsula, according to statements released by the Seoul foreign ministry. Cho emphasized the country’s willingness to resume dialogue between Washington and Pyongyang, working closely with U.S. partners. In line with this approach, the foreign ministers pledged to keep the global community informed of progress and to maintain pressure on North Korea to comply with its international obligations.
While the brief meeting at the G20 headquarters emphasized shared goals, it also underscored the continued necessity for coordination among the three nations in ensuring the enforcement of sanctions, managing regional tensions, and fostering a peaceful, denuclearized Korean peninsula. The collective stance signals a renewed joint effort as the international community watches the unfolding developments in East Asia.
