North Korea’s UN Mission said Friday the country has gained “nothing but a sense of betrayal” since its leader Kim Jong Un and US President Donald Trump committed to establishing a new relationship. The mission said in a summary of its assessment of North Korea-US relations obtained by The Associated Press that “indignation of our people has culminated” and “the currently imbalanced situation can no longer be allowed.”

Since the US has failed to take reciprocal measures to North Korea’s suspension of “a number of actions” which the Trump administration is concerned about, the mission said there is no reason for further restraint.

“We have no leeway any longer,” the North Korean mission said. “It is quite natural for us to bolster our capabilities in order to undercut visibly

growing threats obstructing our security and development,” the mission said. “Nobody has the right to find fault with or to interfere with it.” US-led diplomacy aimed at ridding North Korea of its nuclear weapons has largely been deadlocked since the February collapse of a summit between Trump and Kim Jong Un in Hanoi. The North Korean leader has demanded the US come up with new, acceptable measures to salvage the nuclear talks by year’s end and Pyongyang has been stepping up its pressures on Washington to make bigger concessions.
