South Korea, the United States and Japan are preparing to hold what would be their first trilateral multidomain exercise as early as this month, military sources said Friday, amid joint efforts to bolster security cooperation against North Korean threats.

Discussions are under way on involving the Theodore Roosevelt, a nuclear-powered aircraft carrier, for the exercise, with details, such as the schedule and the scale of the drills, yet to be confirmed, a military sources said, according to South Korea's Yonhap News Agency.
South Korea, the US and Japan agreed to launch the exercise, named Freedom Edge, during their three-way talks held on the sidelines of the Shangri-La Dialogue security conference earlier this month.

Under the agreement, the exercise will take place across various domains, including air, maritime, underwater and cyber.

In April, the three countries held a two-day naval exercise involving the USS Theodore Roosevelt in efforts to improve their joint operability against "North Korea's evolving threats".
