Biden, South Korea to coordinate on North Korea nuclear threat response

President Joe Biden and South Korea's leader are consulting on how to check a nuclear threat from North Korea.

Speaking to reporters aboard Air Force One as Biden made his way to South Korea, White House national security adviser Jake Sullivan said the U.S. has coordinated with Seoul and Tokyo on how they’ll respond should the North conduct a nuclear test or missile strike while Biden is in the region or soon after. Sullivan also spoke with his Chinese counterpart Yang Jiechi earlier in the week and urged Beijing to use its influence to persuade the North to cease the tests.

"China should contemplate taking whatever steps it can to reduce the possibility of a provocative" act, Sullivan said.
