H.R. 3429 — US-Japan-ROK Trilateral Cooperation Act

This section expresses the sense of Congress that the United States should strengthen trilateral cooperation with Japan and the Republic of Korea to address regional challenges and promote a free, open, and resilient Indo-Pacific region. It highlights the August 18, 2023, Camp David summit as establishing a framework for ongoing security, maritime, and information-sharing efforts, and calls for regular Trilateral Leaders’ Summits and a new US-Japan-ROK Inter-Parliamentary Dialogue.

This section directs the Secretary of State, within 180 days of enactment and in consultation with Congress, to negotiate a written agreement with Japan and the Republic of Korea establishing a US-Japan-ROK Inter-Parliamentary Dialogue. It creates a United States Group of up to eight Members of Congress—two each appointed by the Speaker, House Minority Leader, Senate Majority Leader, and Senate Minority Leader, with at least one from the relevant foreign affairs committee per chamber—to meet at least annually with legislative counterparts from those countries and report expenditures to the House Foreign Affairs and Senate Foreign Relations Committees.
