US, South Korea and Japan vow 'complete' North Korea denuclearisation in Atlanta talks
Secretary of State Marco Rubio and his South Korean and Japanese counterparts reaffirmed their commitment to North Korea's complete denuclearisation and full UN sanctions enforcement in Atlanta, and signed a new Trilateral Arctic Pacific Partnership.
The United States, South Korea and Japan have reaffirmed their commitment to the complete denuclearisation of North Korea during trilateral talks in Atlanta, even as Pyongyang continues to reject disarmament and speculation grows about a possible meeting between US President Donald Trump and North Korean leader Kim Jong Un. The pledge came in a readout from the US State Department after the three countries' foreign ministers met on Friday on the sidelines of the Group of 20 foreign ministers' meeting in the US state of Georgia.
US Secretary of State Marco Rubio met South Korean Foreign Minister Cho Hyun and Japanese Foreign Minister Toshimitsu Motegi for their fourth trilateral gathering this year, following meetings in Turkiye in July, the Philippines later that month and New York in September. The State Department said the three ministers reaffirmed their resolute commitment to the complete denuclearisation of North Korea and to the full implementation of United Nations Security Council resolutions.
That implementation pledge carries a specific economic edge. The ministers committed to enforcing UN sanctions that prohibit activities generating revenue for North Korea's nuclear and ballistic missile programmes, a category that has included cyber theft, overseas labour and illicit shipping. South Korea's foreign ministry added that the three countries agreed to maintain a robust deterrence posture against the North through close coordination, while continuing to pursue peace, stability and denuclearisation on the Korean peninsula through dialogue and diplomacy.
The meeting took place one day after North Korea launched around ten short-range ballistic missiles from the Wonsan area towards the East Sea, according to South Korea's Joint Chiefs of Staff. The launches were a reminder of why the three allies keep returning to the same language: Pyongyang has enshrined its status as a nuclear-armed state in law and has repeatedly declared its atomic arsenal permanent and irreversible, rejecting the very goal the trilateral statement restates.
Pyongyang's response to the latest diplomatic activity was swift. On Saturday it denounced a joint statement by a group of nations monitoring sanctions implementation against it, vowing that what it called the stereotyped sanctions racket of the United States and the West could neither influence the position of North Korea as a nuclear weapons state. The statement underlined the gap between the allies' stated objective and the North's declared position, a gap that has defined Korean peninsula diplomacy for years.
Beyond the Korean peninsula, the three ministers signed a memorandum of cooperation establishing the Trilateral Arctic Pacific Partnership, a new framework intended to expand maritime and economic cooperation in the Pacific Arctic region. The partnership reflects a widening of the trilateral relationship beyond security alone, into shipping routes, resources and economic ties in a region where melting sea ice and great-power competition are reshaping strategic calculations.
The Atlanta meeting also sits within a wider diplomatic calendar. Speculation has mounted over a possible meeting between Trump and Kim at next month's Asia-Pacific Economic Cooperation summit in China, with Trump making repeated overtures towards the North Korean leader. No such meeting has been confirmed, and previous Trump-Kim encounters produced declarations rather than a denuclearisation agreement, but the possibility has given fresh salience to the allies' coordination.
For South Korea and Japan, the trilateral format matters because their own bilateral relationship has often been strained by history, even as both depend on the American alliance. Meeting together with the United States allows Seoul and Tokyo to present a united front on North Korea while also building practical cooperation in areas such as the Arctic, where their economic interests increasingly overlap. The regularity of the meetings this year, four in ten months, signals that the format is now a standing feature of their diplomacy rather than an occasional event.
The practical test of the Atlanta pledges will come in enforcement and in Pyongyang's next moves. Sanctions implementation depends on monitoring shipping, financial flows and cyber activity across many countries, and North Korea has shown considerable skill at evading restrictions, including through cryptocurrency theft. Further missile launches or a new nuclear test would test the allies' deterrence posture, while any diplomatic opening at the APEC summit would test whether their commitment to dialogue can produce more than restated principles.
For now, the Atlanta statement does two things at once: it closes ranks among the three allies ahead of a potentially consequential few weeks, and it keeps the long-standing goal of complete denuclearisation on the record at a moment when Pyongyang insists that goal is closed. Whether that goal moves any closer will depend less on the wording of joint statements than on what happens at the negotiating table, in the waters around the peninsula, and in the enforcement of the sanctions the three ministers have pledged to uphold.
