Despite tough talk, China's North Korea options limited

BEIJING (Reuters) - Unprecedented Chinese criticism of North Korea is unlikely to mean tough new action against Pyongyang because if China pushes too hard and its troublesome neighbour collapses, the result would be disastrous for Beijing.

That limits the options for China, even as it has grown frustrated with Pyongyang since the reclusive state carried out a third nuclear test in February and ramped up the sabre-rattling in response to the U.N. sanctions that followed.
