Right after taking office, Park restructured the Blue House and government organization to carry out her administrative vision. The Office of National Security at the Blue House, Ministry of Science, ICT and Future Planning, and Ministry of Oceans and Fisheries were newly launched, and the seat of Deputy Prime Minister for Economic Affairs was revived. The Chief of the National Security Office would act as a "control tower" for diplomatic, security, and national defense issues, and the Deputy Prime Minister for Economic Affairs for economic, social, and welfare issues.
