United Nations monitors claims that North Korea is taking measures to ensure that its nuclear and ballistic missile capabilities are untouched by the United States. The warning was released before the planned meeting between the United States and North Korea takes place as they prepare for a second denuclearisation summit.

Stephen Biegun, the U.S. special envoy for North Korea, is scheduled to meet his North Korean counterpart on Wednesday in Pyongyang in preparation for the summit later this month. According to the U.S. State Department on Monday, President Donald Trump and North Korean leader Kim Jong Un are expected to meet during the summit.

Beigun said that he is hoping that the meeting with the new North Korean counterpart Kim Hyok Chol starts "a set of concrete deliverables" for the summit between the two leaders. The U.S. envoy is scheduled to meet South Korean officials in Seoul on Sunday and Monday. He said that he is aiming to produce a forward directed negotiation and declarations and he also wants a shared understanding of the desired outcomes of their joint efforts.

South Korean officials and the United States is trying to look at a compromise that could expedite the North's denuclearization. The South Korean's believe that it might be reciprocated by U.S. measures including ending the 1950-53 Korean War and setting up a liaison office.

According to the report of the U.N. sanctions monitor submitted to a 15-member U.N. Security Council sanctions committee, the evidence is found that concludes that there is a consistent trend on the part of the North Korea to disperse its assembly, storage, and testing locations.

The North Korean mission to the United States failed to immediately give their comment on the report which was submitted to the U.N. Security Council on Friday. Trump and Kim first met last June in Singapore and it yielded a vague commitment from the North Korean leader in working towards denuclearization of the Korean peninsula. Troops of the United States have been stationed in the peninsula since the 1950-53 Korean War.

According to reports, Danang, a Vietnamese resort town, is seen as the most likely location for the next meeting of the two leaders.

Trump said on Thursday that his dealings with North Korea gain "tremendous progress". However, the public believes that there were no concrete steps to encourage North Korea to give up its nuclear weapons program.
