I really don't think that the CCP can survive this. I think that tough times are coming, and IMHO, a more democratic government will emerge when the dust settles.
I think the answer to this question is interesting: How bad is the problem? What are the chances that China could suffer a debt crisis like the one the US faced in 2008 or certain euro zone countries are facing now?
The banks will be saved, but inflation will fall on the people. It's already becoming unbearable. I think the government is going to be between a rock and a hard place.
