Yeah if we look at the historical perspective it doesn't end well and you can see they are trying to get ahead of this and by themselves more time to prevent a collapse but time is fickle esp. if they jump into a war with Taiwan would lead to an enormous human capital toll that China cannot spare or you run into the issues Russia is running into now with ethnic Russians getting decimated so they are sending minorities into the meat grinder instead.

I believe that the demographic collapse of Chinese society presents us with sociological and economic, but also psychodynamic challenges and complex questions that we cannot even begin to comprehend at this point, let alone answer. It is clear that this transition can have dramatic consequences for all established social and economic systems in a society. We will observe this closely in order to be able to draw conclusions for our societies.
