BBC: China and the US have vowed to work together to persuade North Korea to give up its nuclear programme and to settle tensions through dialogue.
A Chinese statement issued during a visit by US Secretary of State John Kerry said the nuclear issue was the "shared responsibility of all parties".
Mr Kerry said the two sides must decide "very quickly" how to proceed.
North Korea has recently threatened nuclear attacks, and is feared to be preparing a missile launch.
A flurry of warlike statements from Pyongyang has prompted speculation that a launch could happen on 15 April, when the country marks the 101st birthday of the nation's founder and former leader, Kim Il-sung. (+ BBC video) » | Saturday, April 13, 2013
