North Korean leader Kim Jong Un could still visit Seoul for the first time in the next few weeks, South Korean President Moon Jae-in said Tuesday, describing the possible trip as a major boost in efforts to make the peninsula nuclear-free. Moon and Kim have met three times in 2018 amid warming ties between the two Koreas, with South Korea hoping to host a first-ever visit by Kim to Seoul before year's end. "There is a possibility that Chairman Kim Jong Un's visit to Seoul may be made within this year, but there's more important things than the timing," he said in translated remarks during a visit to New Zealand.
