Sejong was founded in 2007 as the new planned capital of South Korea from many parts of the South Chungcheong province and some parts of North Chungcheong province to ease congestion in South Korea's current capital and largest city, Seoul, and encourage investment in the country's central region. Since 2012, the government of South Korea has relocated numerous ministries and agencies to Sejong, but many still reside in other cities - principally Seoul where the National Assembly and many important government bodies remain.
