Japan in the 2000s was already a wealthy developed country with Per Capita GDP on par with the USA.Not by my calculations.
Chinese (red) line from 1990s to today is roughly where Japan (blue) was up to year 2000 or so, adjusted for a few percent.
Or where US (light blue) was up to, say, late 1960s. Though i don't expect as many ups and downs as the US had for China. The same reason is why Singapore or Taiwan are not good comparisons. They're too small, too dependent on outside influences, on particular products and services. Small systems are more easily pushed around. Large systems like China are heavy and have huge inertia. They won't see big ups and downs in such short periods of time.
So Japan had no prospects for continued fast growth.
There is no way that China from 1990s to today is equivalent.
On an exchange rate basis, the average Chinese person is currently 5x "poorer" than the US average.
On a PPP basis, it is 3x "poorer" than the US average.
It means China does still have the potential to continue with fast catchup growth for the next 10+ years.
So the graphs you have listed are not relevant comparisons.
For example, there are still over 360Million rural peasant farmers in China who are still to catch up and join their urban counterparts. Just this subsection of the Chinese population can reasonably be expected to add another $10 Trillion of economic output in the next 20 years.
