The United States is not discussing joint nuclear exercises with South Korea, US President Joe Biden has said,

appearing to contradict remarks by his South Korean counterpart, President Yoon Suk-yeol, that Washington and Seoul were in talks on exercises involving US nuclear assets.

The South Korean president said in a newspaper interview that Seoul and Washington were in “talks on joint planning and exercises involving US nuclear assets to counter North Korea’s nuclear threats”.

Asked by reporters at the White House on Monday if he was currently discussing joint nuclear exercises with South Korea, Biden said, “No”.

President Yoon’s comments, in an interview published in the Chosun Ilbo newspaper on Monday, come at a time of growing tension with North Korea,

which test-launched an unprecedented number of ballistic missiles in 2022 and has promised to robustly counter what it views as military planning by the US and South Korea for a possible invasion.

In response to North Korea’s sabre rattling, Yoon has taken an increasingly tough stance and has called for “war preparation” with an “overwhelming” capability.
