The 15-member council will on Monday hold its the first-ever meeting on the situation in North Korea, despite objections from China - Pyongyang's key ally - and Russia.
"We cannot recognize the Security Council meeting. Its mandate is not human rights," said political counselor Kim Song from the North Korean mission at the United Nations.
"We will not attend," he told AFP yesterday.
Under UN procedures, North Korea can send a representative to the meeting of the top UN body and diplomats had said they were hoping for a face-to-face discussion with Pyongyang's envoy.
