President Yoon Suk Yeol on Friday tapped Ambassador to Russia Chang Ho-jin for first vice foreign minister, his office said.
Yoon also nominated current First Vice Foreign Minister Cho Hyun-dong to be ambassador to the United States, according to presidential spokesperson Lee Do-woon.
The nominations come after the sudden replacement of National Security Adviser Kim Sung-han last week over alleged lapses in planning for Yoon's state visit to Washington later this month.
Kim was replaced by Ambassador to the U.S. Cho Tae-yong.
Both Chang and Cho are career diplomats. Chang previously served as ambassador to Cambodia, while Cho Hyun-dong served as minister at the South Korean Embassy in Washington, among other posts.
