You think China will separate into 2 or multiple nations anytime in the future? I just think that over billion people is too much of a task for one government?
For the most part China is already a divided nation. I don't mean the SAR Macau or SAR Hong Kong. Quite simply they have virtual SAR like states within their own borders.
Firstly there are SEZs, Special economic zones.
It is divided in other ways though, via ethnicity's, language, food and wealth. I think as I have touched on many times eventually there will be separatists. The CCP will probably try to hold on to it as long as possible or bribe them to stay. But who knows about the future? It is like one of those debates about a new US civil war coming. It's possible. Though I give the CCP of China another 10 years 15 tops as some real big issues are stacking up and anger is being stoked such as Chinese ant colonies.
