A LETTER from U.S. President Donald Trump was sent to Kim Jong Un, top leader of the Democratic People’s Republic of Korea, over the weekend, U.S. media reported Monday.

The letter “was flown to Pyongyang and delivered by hand,” reported CNN citing an anonymous source whom the cable network said was familiar with the ongoing negotiations between the two sides.

It has also been reported that Kim Yong Chol, vice chairman of the ruling Workers’ Party of Korea Central Committee, may meet U.S. Secretary of State Mike Pompeo later this week in Washington.

Washington and Pyongyang have been working on details of the expected second Trump-Kim meeting.

Kim said last week during his stay in China that his country will make efforts for the second summit to achieve results that will be welcomed by the international community.

Trump said earlier this month that he expected to meet Kim in the “not-too-distant future,” after receiving a “great” letter from the top DPRK leader.

Chinese Foreign Ministry spokesperson Lu Kang said at a daily briefing Friday that China always encourages the DPRK and the U.S. to resolve their own concerns through dialogue and consultation.  (Xinhua)
