SEOUL, June 1 (Xinhua)-- South Korean President Park Geun-hye on Sunday nominated the incumbent Defense Minister Kim Kwan-jin for the post of top presidential security adviser.
Presidential spokesman Min Kyung-wook told a press briefing that Park named new top security adviser and defense minister to make sure defense readiness and to prevent vacuum in national security.
Kim, who served in various military posts including field, operations and strategy, has been responsible for national defense over the past four years.
In the meantime, he had severed as a member of the national security council and the ministerial meeting of foreign affairs, unification and security, the spokesman said.
Han Min-koo, former head of the Joint Chiefs of Staff (JSC), was named as new defense minister to replace the outgoing Kim.
Han served in the posts of army chief of staff, capital defense commander and top negotiator in the inter-Korean ministerial meeting.
On May 22, President Park accepted resignations from former presidential security advisor Kim Jang-soo and spy agency chief Nam Jae-joon.
Kim had been criticized after he said the national security office in charge of security, defense and foreign affairs was not a control tower of disasters and sought to shun his responsibility of the ferry sinking accident.
The ferry Sewol capsized and sank off the southwestern coast on April 16, leaving more than 300 people, mostly high school students, dead or missing.
Nam has been a long-time target of opposition criticism since Park took office in February 2013.
The National Intelligence Office (NIS) interfered with the 2012 presidential election and forged evidence to charge a former Seoul municipal government official with espionage.
President Park apologized for the spy agency's evidence forgery scandal on April 15, just a day before the ferry sinking accident occurred.
The spokesman said successor of the NIS chief will be announced after verification works are completed.
