The US-Japan-ROK Trilateral Cooperation Act aims to strengthen cooperation among the United States, Japan, and the Republic of Korea (ROK) by establishing a formal dialogue between their legislative bodies. The main objective is to enhance collaboration on shared interests and values, particularly in addressing regional challenges and promoting stability in the Indo-Pacific region. Key provisions of the Act include the establishment of a US-Japan-ROK Inter-Parliamentary Dialogue, which will be negotiated by the Secretary of State within 180 days of the Act's enactment.
