Su-35 had its chance when China asked for permission to incorporate domestic missile/avionics but Russia never gave the go ahead.
The Russians really messed up by not partnership up with China when they had a chance. But I guess they also have to maintain that facade in order to keep getting export sales.
Normally for every weapons system we see in China's weapons trade shows there's some corresponding weapons system adopted within the PLA (if not from the same tech tree, then at least filling similar roles and capabilities), whether that's revealed to public or not. We have seen a *lot* of very diverse PGM models at those trade shows over the years. That would suggest at least that the PLA's PGMs suite ought to be decently comprehensive. What's less clear is the extent of integration of the weapons into standard operations.
I believe Shilao/Yankee said that they train extensively and that they are between US and Russia in terms of the # of PGMs they have. Based on them talking about this so extensively, I think this number is growing fast.
The other thing is that with the proliferation of drones and small PGMs/ground attack missiles, PLA is likely to just use drones to terrorize ground target (after achieving air dominance).
I have an entire essay in my head about the population decline economic doom thesis (I have an entire book in my head about ideas that establishment economists and adjacent public commentators get wrong about economic growth and development). But the cheeky tweet form of that essay is "What will happen first, the economy losing its labor force to population decline or everyone losing their jobs to robots".
The problem is that certain people like Peter Zeihan keep getting air time, because people want to hear that China will suddenly collapse and that manufacturing will come back to America.
Half of the most recent college graduating class from China could not secure job offers. That does not sound like an economy that's running out of labors. For the foreseable future, I think the Chinese government will be more preoccupied with trying to create meaningful jobs rather than not having enough labors.
When the recent Baidu robotaxi came out, one question was how do you keep employed when robotaxis don't need humans anymore. For example in Beijing, you can't only be a taxi driver if you are from Beijng proper or surrounding areas. Local government really still try very hard to create employment opportunities.
Now, I do think China needs to reverse its population trend if it wants to keep developing talented individuals needed to drive innovation and development. They don't want to become Japan, SK or Singapore or even Taiwan, where people are just not having children.
