It's really interesting that you mention China because seems to start to get a bit annoyed and ashamed by North Korea. What North Korea is doing is very bad for business (and war would hurt it even more so), North Korea is not a significant trade partner and China doesn't care about ideology any more as these days it's a communist country only in name; it's de facto a capitalist dictatorship. I don't think China will abandon North Korea but I also don't think they would be as willing to support North Korea as they have done in the past.
