Their society is rapidly improving. The less they fight, the better off they'll be. What will fighting get them apart from ruin?
It isn't a guarantee of peace, obviously. The same logic applies to everyone and there are still a lot of wars. But the warmakers tend to struggle to achieve the sort of results that the Chinese do and as a government they have a 50 year history of success through peace not war.
HDI growth in China is levelling out, and irredentist claims to Taiwan are a foundational piece of the CCP's ideology. The "strategic ambiguity" could be tolerated while Taiwan was relatively unimportant, but now that TSMC is one of the most important companies in the world, China is certainly at least considering war.
Their society is rapidly stagnating with a disastrous demographic profile. And since it's now a dictatorship the decision ultimately comes down to one man: Chairman Xi. No one knows what's going on in his head so we have to assume the worst.
Yeah but the Russians didn't declare war because of their demographics. In fact, if you ask them why this happened Putin gave a whole speech [0] on this when he sent the troops in, which can be neatly summarised:
> We are talking about what causes us particular concern and anxiety, about those fundamental threats that year after year, step by step, are rudely and unceremoniously created by irresponsible politicians in the West in relation to our country. I mean the expansion of the Nato bloc to the east, bringing its military infrastructure closer to Russian borders.
It isn't obvious that China is dealing with the same sort of pressures in East Asia.
They would still probably do it, mind you, but it would be a huge scandal and a subject of existential dread for Russian media and elites.
The fact that they've been stripping their NATO borders bare with barely anyone noticing or caring shows that nobody views the prospect of a NATO invasion as realistic. It was always a fig leaf.
(Although maybe there were scandals and I never heard of them. My exposure to Russian media is filtered through Western media. But I heard about other scandals and anxieties.)
