U.S. Ambassador to the United Nations Linda Thomas-Greenfield is planning to travel to South Korea to discuss pending issues, a foreign ministry official said Friday.

Earlier, Japanese broadcaster NHK reported that Thomas-Greenfield is making arrangements to travel to South Korea and Japan in mid-April for possible meetings with government officials, citing diplomatic sources.

“We are in talks with the U.S. on the ambassador to the U.N.’s visit to South Korea,” the official said.

Thomas-Greenfield is expected to meet with high-level officials in Seoul to discuss cooperation on various pending issues on the U.N. Security Council, including the North Korean nuclear issue.

South Korea and Japan currently serve as two of 10 nonpermanent members of the U.N. Security Council. The United States is one of the five permanent members of the council.
