Seoul: South Korea`s new President Moon Jae-in said on Wednesday he was prepared to visit North Korea and was ready to negotiate with China and the United States over a controversial anti-missile defence system soon after he was sworn in on Wednesday.

Moon took the oath of office in a simple ceremony in the domed rotunda hall of the Parliament building, a day after his liberal Democratic Party`s decisive victory in a snap election called to find a replacement for Park Geun-hye, who was ousted in March over a corruption scandal.
