Pyongyang's top nuclear envoy denounced reports of North Korean nuclear assistance to Syria as baseless allegations "fabricated by lunatics" as he arrived Tuesday for talks with Chinese officials.
Following his arrival in Beijing, Kim Kye Gwan said the latest round of six-nation talks on ending the North's nuclear programs could be a make-or-break occasion.
Envoys from the two Koreas, China, the United States, Japan and Russia are scheduled to meet from Thursday to lay out a program for disabling the North's programs.
"During this round of talks, if we can agree on measures to implement what we have already reached a consensus on, then we can proceed with the process," Kim told reporters on arrival at Beijing airport. "If not, it could go back to square one."
