North Korean nuclear negotiating chief Kim Myong Gil said he rejected the US "placebo" proposal in December.

"If negotiations can resolve the current situation, we are ready to meet the US wherever and whenever," North Korea's state news agency KCNA said on November 14, quoted Kim Myong Gil as the chief negotiator of the county. US businessman Stephen Biegun has proposed that the two sides meet for a third time in December.

Kim, however, said his Biegun counterpart had a "dangerous purpose", only to appease North Korea before the end of the year. "We are not willing to participate in such negotiations," the North Korean official said.

Stephen Biegun and Kim Myong Gil led the US-Korea delegation on a working-level negotiation in Stockholm, Sweden last month, but the talks ended with no results. Pyongyang has repeatedly accused Washington of an inappropriate and threatening approach if this does not improve by the end of this year, relations between the two countries "may end immediately".

After the US-North Korea summit in Hanoi did not achieve the expected results, North Korean President Kim Jong-un in April issued a deadline at the end of the year for Washington to show more "flexibility" in the lifting of sanctions on Pyongyang. North Korea has tested missiles several times since the beginning of the year, apparently to "warn" the US about the weapons it is developing.
