South Korea, the United States and Japan renewed their commitment to the complete denuclearization of North Korea while broadening cooperation on economic security and emerging technologies. Foreign Minister Cho Hyun, US Secretary of State Marco Rubio and Japanese Foreign Minister Toshimitsu Motegi met in Atlanta during the Group of 20 gathering, holding their first trilateral ministerial talks in roughly a month.
The ministers backed full enforcement of UN Security Council resolutions, including restrictions on revenue-generating activities linked to Pyongyang’s nuclear and ballistic missile programs. They also endorsed the Multilateral Sanctions Monitoring Team, which documents sanctions violations and efforts to evade international restrictions. The joint position connects the denuclearization goal with continued scrutiny of the financing and procurement networks that sustain the prohibited programs.

Cho said Seoul would continue acting as a “pacemaker” for renewed dialogue between Washington and Pyongyang and for a lasting peace framework, while maintaining coordination with the United States. His remarks placed diplomatic outreach alongside sanctions enforcement, although the available evidence did not identify a new negotiation timetable or a specific proposal for restarting talks.
Regional security joins the trilateral agenda
The three ministers also emphasized stability in the Taiwan Strait. Rubio raised concerns about Chinese activity in the South China Sea, East China Sea and Yellow Sea, as well as China-Russia cooperation affecting Indo-Pacific security. These issues expanded the meeting beyond North Korea and situated the trilateral framework within wider regional security tensions.
Economic security formed the other major strand of the talks. The governments agreed to pursue more diverse critical-mineral supply chains, cooperation on small modular reactors, and work on artificial intelligence and other emerging technologies. They also signed a memorandum establishing the Trilateral Arctic Pacific Partnership, intended to expand maritime and economic cooperation in the Pacific Arctic. Implementation will depend on how the three governments turn those commitments into projects, supply-chain arrangements and sustained coordination.
