South Korea, the United States and Japan have agreed to launch a new trilateral multidomain exercise named Freedom Edge this summer.

According to Seoul’s defense ministry, defense minister Shin Won-sik and his American and Japanese counterparts, Lloyd Austin and Minoru Kihara, reached the agreement Sunday during their talks held on the sidelines of the Shangri-La Dialogue in Singapore. 

The Freedom Edge exercise will include various domains, including air, maritime, space and cyberspace.

The exercise takes its name from key bilateral exercises the U.S. holds with its two Asian allies — Freedom Shield with South Korea and Keen Edge with Japan.

The three nations have held joint maritime and air drills, but Freedom Edge would mark the first trilateral multidomain exercise. 

The latest agreement on the new exercise comes after the leaders of the three nations agreed to hold multidomain trilateral defense exercises on a regular basis during their summit talks in August last year. 

The three sides also agreed to establish a trilateral security cooperation framework within this year to institutionalize their three-way defense cooperation.
