Pyongyang's ambassador Han Tae Song said at the UN disarmament talks in Geneva that the "Washington regime […] is obsessed with the wild game of reversing DPRK's development of nuclear force which has already reached the completion phase."
The North Korean envoy vowed that Pyongyang's upcoming measures "will make the US suffer the greatest pain" it has ever experienced.
The diplomat voiced his country's condemnation "in strongest terms" and "categorical" rejection of new UN Security Council's sanctions against Pyongyang, adopted on Monday as a response to North Korea's most powerful nuclear test conducted on September 3.
When commenting on the adoption of new sanctions, US Ambassador to the UN Nikki Haley said the "strong relationship" between US President Donald Trump and Chinese President Xi Jinping played a major factor in passing the resolution.
