From AP, via the Washington Post:

China has pledged to try reviving talks aimed at ending North Korea’s nuclear programs following the isolated, Stalinist state’s declaration that it has atomic weapons and is boycotting disarmament negotiations.

The United States and other countries involved in the six-party talks have urged China to use its influence over North Korea. Beijing is Pyongyang’s last major ally and a key supplier of food and energy to the impoverished dictatorship.
