President Park Geun-hye has nominated First Vice Foreign Minister Kim Kyou-hyun as the head of the recently-revived National Security Council secretariat.
Kim, a veteran diplomat, has served as a deputy chief mission to the United States and the deputy foreign minister.
The presidential office of Cheong Wa Dae says his leadership, as well as his negotiation and crisis management skills were the main reasons behind the president's decision.
The NSC secretariat was shut down by the Lee Myung-bak administration back in 2008.
President Park ordered that it be re-established in December in consideration of the growing threats from North Korea and escalating tensions in Northeast Asia.
