The president of China is just a glorified code reviewer to some policies made by policy agency bodies. Sure he commands lots of political control over the broad contours of those policies, but nevertheless the control is limited.
What matters is making the right decisions, regardless of whichever 'ism' camp they belong to. Just do what is right, and what it takes to win.
This is seems to be more like a guiding principle behind whatever China does. During Deng era they redefined what communism means, they keep redefining communism as whatever they have to do to win.
Which in itself is a strange thing. They don't seem to care all that much ideologies, or anything for that matter. Only winning and what it takes to win seems like their ideology.
>>A Taiwan invasion attempt that brings massive blockades and boycotts
Another great part about China seems to be a stubborn refusal to fight wars. Which is a very scary thing if you think about it. The USA has perfected one weapon in all its existence, and its biggest nemesis is inert to it.
By and large they are just minimising going down decision trees that end in failure.
>>Demographic collapse from decades of poor fecundity
Tall order. Every one's fertility rate is declining. More importantly due to proliferation of AI and automation, this is actually a welcome thing. Lesser the mouths to feed, lesser instability when the machines inevitably take over.
