Tired of shitty think tanker's China collapse theory, so I will give them a better one:
China will never be successful because it is passive. Throughout history nations become strong or weak. When China is strong, they feel self-righteous and stop expanding itself. When smaller countries become strong, they expand and exterminate any future competitors. China never take advantage of its strength, so it is only a matter of time when it becomes weak again and get taken over by currently weaker neighbours. All you need to do is making Chinese feel self-righteous and leave them alone, and they will implode on itself.
^ There, an actually plausible China collapse theory.
