"I believe North Korea needs to take practical denuclearization steps more boldly if it wishes to resolve the issue of international sanctions because the issue of international sanctions depends on the speed of North Korea's denuclearization process," Moon said during a press conference, as quoted by the Yonhap news agency.
Moon Jae-in's remarks come as the situation on the Korean peninsula has improved since the beginning of 2018 as North Korean leader Kim Jong-un engaged in an active dialogue with Moon and US President Donald Trump.
During the landmark Kim-Trump summit in June, the two leaders agreed that Pyongyang would make efforts to denuclearize the Korean peninsula in exchange for the United States and South Korea freezing their military drills as well as the potential removal of US sanctions.
