Next 20 years is when PRC will really start cooking. In that period, PRC going to be doubling/tripling skilled workforce more than they have now (currently slightly above parity with US), this is already baked in from past 20 years of birth and current tertiary trends. That workforce, the greatest high skill demographic dividend in recorded history, will hang around for another 40+ years. They will have 40-60 years of operating with as much high end talent as OECD combined within a coordinated system. Past 2080, unless they sort out TFR, things could go bad, but for relevant timeframes, i.e. most of our lifetimes, they're going to be peaking.

The population pyramid for 2045 for China is not favorable ( https://www.populationpyramid.net/china/2045/ ). Currently the 30-39 bracket is 121 million, but by 2045 it will be about 83 million.
You could be arguing that the percent of skilled labor workforce in there will be going up over the next 20 years - but the size of the bracket is drastically decreasing while it becomes more and more weighted to the 65-85 age bracket.
