North Korean leader, Kim Jong Un has expressed great satisfaction after receiving a letter from the United States president, Donald Trump ahead of a second summit between them.

Kim was handed the letter on Wednesday by a North Korean envoy, Kim Yong Chol who met Trump at the White House last week and gave him a missive of his own.

Chol had come with negotiations between Pyongyang and Washington on their nuclear arsenal deadlock.

After their discussions, Trump had said his next summit with the North Korean leader would probably take place near the end of February but did not give an exact date or location.

According to the state owned Korea Central News Agency (KCNA), Kim Jong Un said his government would believe in Trump’s positive way of thinking and ordered that preparations for the second meeting be made.

The first encounter between both leaders was a high-profile summit in Singapore in June, the first ever meeting between a sitting US president and a North Korean leader where they signed a vaguely-worded document in which Kim pledged to work towards the denuclearization of the Korean peninsula.

However, progress on the deal has since stalled. While Pyongyang is seeking sanctions relief and rejects demands for what it calls its unilateral disarmament, Washington insists that the measures must stay in place until she gives up its nuclear arsenal.
