Divisions within PRC over DPRK?

NYT story on perceived divisions within China over how to respond to latest NorKo shenanigans.

While China’s decision-making on core foreign policy issues tends to be secretive, American officials said they had picked up hints that there was some disagreement within the leadership about how to respond to North Korea’s behavior, pitting civilian party leaders against the military.

The debate surfaced last year after North Korea tested a nuclear device, American officials said, and has accelerated since the attack on the South Korean ship, the Cheonan. Chinese civilian leaders have expressed growing puzzlement and anger about the North’s behavior, these officials said, while military officials tend to see the North’s moves as more defensible given the threat North Korea perceives from the United States.

Unsurprising split.  Just interesting that it's becoming apparent to outsiders.
