Kim sent a letter to Moon on Sunday to commemorate the dramatic detente they engineered this year, including three summits, after years of confrontation marked by a series of the North's nuclear and missile tests.
Kim was sorry his plan to visit Seoul this year did not take place as agreed at their third summit in Pyongyang in September, expressing his "strong resolve" to make it happen in the future while monitoring the situation, Moon's office said.
