China is officially South Korea's ally, yet it seems to be taking sides with South korea more and more.
With friends like that eh... Just kidding, it's not like North Korea has treated its ally pretty well either, so I guess China is saying that if its ally is going to give China so many headaches, who needs that ally. Besides, the only thing China gets out of such an alliance is prevention orf a war that leads to a refugee crisis on its border.
I hope they do. Instead of having a crazy tyrant they'd have a pragmatic one. Either that or cut them off. I imagine North Korea is more a nuisance to China than an actual ally.
There were suspicions in China a while back that its 'ally' was counterfeiting Chinese currency.
