BEIJING -- China on Wednesday had some stern words for North Korea, after Pyongyang announced plans to launch a rocket it claims will carry a satellite.

Yet Beijing has also resisted imposing tough sanctions on the North, such as a ban on oil shipments. More than anything, China wants to maintain the status quo on the Korean Peninsula. This poses a dilemma for Chinese leaders as the Kim Jong Un regime grows increasingly unpredictable -- and, perhaps, uncontrollable.
