South Korea’s Yoon calls for strong security cooperation with US, Japan

South Korea’s president called for deeper security cooperation with the U.S. and Japan to address North Korea’s nuclear threat, saying Tuesday that his upcoming summit with the U.S. and Japanese leaders at Camp David will “set a new milestone in trilateral cooperation.”
It will be the first time for the leaders of the three countries to gather specifically for a trilateral summit, rather than on the sidelines of international meetings. This suggests they are serious about boosting their ties in the midst of complex regional challenges such as North Korea’s advancing nuclear arsenal and Washington’s strategic rivalry with Beijing.
In their summit Friday at the U.S. presidential retreat in Maryland, President Joe Biden, South Korean President Yoon Suk Yeol and Japanese Prime Minister Fumio Kishida are expected to announce plans for expanded military cooperation on ballistic missile defense and technology development, according to two senior Biden administration officials.
