The Japan Institute of International Affairs held the 3rd Japan-US-ROK Trilateral Dialogue Initiative (TDI) virtually on July 29 and 30, 2021, with the Carnegie Endowment for International Peace (CEIP) and the Korean National Diplomatic Academy (KNDA).

Experts and government officials from the three countries actively exchanged their views on North Korean policies and various issues in the Indo-Pacific region.
