On Sunday, North Korean leader Kim Jong Un addressed a letter to South Korean President Moon Jae-in calling for peace talks between leaders for the new year after their active engagement in 2018. The Blue House did not reveal completely Kim's letter.
Moon tweeted then thanking Kim for his "warm" letter and said without specifying that Kim had expressed his willingness to implement the agreements reached this year. He also said there will be many more difficulties ahead. "However, our hearts will become more open if we deploy so much effort. We do not wish to welcome President Kim (to the south) in our hearts. "
At the three summits between Moon and Kim this year, the Koreas accepted various goodwill gestures and pledged to resume economic cooperation where possible, expressing optimism that international sanctions would cease to allow such activity.
Moon's office did not reveal how Kim Jong-un's speech was delivered or commented on the second summit scheduled for Trump in 2019.
The letter comes a few days before Kim is invited to speak to North Koreans in the New Year's speech.
Kim and Trump are trying to hold a second summit in early 2019.
