Beijing called on Tuesday for a prudent approach to the situation on the Korean Peninsula after Pyongyang warned of an impending nuclear warhead test and launch of several ballistic missiles.

China also reaffirmed that United Nations resolutions should be fully implemented.

"We urge all sides to conscientiously carry out the UN Security Council resolutions, speak and act cautiously, and not take any action that would exacerbate tensions on the Korean Peninsula," Foreign Ministry spokesman Lu Kang said at a regular news briefing.
