S. Korea, U.S., Japan Reaffirm Deterrence Commitment at Manila Talks

MANILA, July 22 (Yonhap) -- The top diplomats of South Korea, the United States, and Japan on Wednesday reaffirmed close coordination on North Korea policy, underscoring their commitment to deterrence against Pyongyang and the denuclearization of the Korean Peninsula, according to Seoul's foreign ministry.

Foreign Minister Cho Hyun, U.S. Secretary of State Marco Rubio, and Japanese Foreign Minister Toshimitsu Motegi agreed to strengthen cooperation during their trilateral talks held on the sidelines of Association of Southeast Asian Nations (ASEAN)-related ministerial meetings in Manila. The three diplomats are in the Philippine capital to attend the ASEAN Regional Forum (ARF), the East Asia Summit (EAS) foreign ministers' meeting, and other related gatherings.

"The three ministers shared their assessments of recent developments on the Korean Peninsula and reaffirmed their commitment to maintaining a robust deterrence posture against North Korea while upholding the goal of the denuclearization of the Korean Peninsula," the ministry said in a statement. "The ministers also agreed to maintain close coordination on North Korea policy and continue communication and cooperation aimed at preserving peace and stability on the Korean Peninsula through dialogue and diplomacy," it added.

The trilateral meeting took place two weeks after the three ministers held talks on the sidelines of the North Atlantic Treaty Organization (NATO) summit on July 7, which the ministry said highlights the importance the three countries place on trilateral cooperation and coordination.

In addition to North Korea issues, the three ministers discussed key risks and areas for policy coordination in economic security cooperation and agreed to deepen practical cooperation in areas such as nuclear energy, critical minerals, and emerging technologies. They also committed to intensifying joint efforts targeting transnational criminal organizations, including networks operating scam centers, and to expanding trilateral discussions on Arctic issues in recognition of the region's growing strategic importance.

The three countries signed a memorandum of cooperation (MOC) to establish a framework for cooperation on accelerating the deployment of small modular reactors (SMRs) in third countries, particularly those in the Indo-Pacific region.

A U.S. State Department readout of the meeting confirmed the discussions, saying the three ministers reaffirmed the importance of maintaining a "unified" approach toward North Korea, underscoring their commitment to the "complete" denuclearization of the North and continued coordination to counter North Korean cyber threats.

North Korea appears to have skipped the ARF for the second consecutive year, as it continues to focus on bilateral diplomacy with Russia and China while shunning multilateral diplomatic engagements.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
