US-Japan-ROK Trilateral Cooperation Act

HR 3429 establishes a formal US-Japan-ROK Inter-Parliamentary Dialogue to deepen trilateral cooperation. It creates a US delegation of up to 8 Congress members (2 each from House/Senate leadership, with committee requirements) to meet annually with Japanese and South Korean legislators. The bill mandates annual reports to the Foreign Affairs and Foreign Relations committees and requires the delegation to rotate leadership between House and Senate every two years. This legislation directly affects US congressional members appointed to the delegation and provides a structured mechanism for ongoing policy coordination among the three nations.
