This came in a statement by the South Korean Air Force, carried by Yonhap News Agency, which spoke of the first joint military exercises conducted by the three countries since President Lee Jae-myung took office on June 4.
The statement said that two South Korean F-15s, six US F-16s, and two Japanese F-2s participated in the maneuvers.
He added that the drills aim to enhance security cooperation between South Korea, the United States, and Japan in light of "North Korea's nuclear and missile threats," and that the trilateral drills are also scheduled to continue.
Following their meeting at the G7 summit in Alberta, Canada, President Lee Myung-bak and Japanese Prime Minister Shigeru Ishiba pledged to strengthen bilateral and trilateral cooperation with the United States "in response to various regional geopolitical crises, including the North Korea issue."
