People who were not Chinese got the same progress like the Chinese did at different speeds (earlier or later).
Those who did either did it on the back of the rest of the world and by plundering and colonizing billions (west and western protectorates) with China still managed to catch up with that in half a century or they just havent yet and wont in the forseeable future (most of the third world) and their progress marely amounts to the most generalized side effects of world wide medical and tech progress. China is bringing to 1.5 billion people the progress, QoL and modernity the former group achieved (and then some) without colonizing, imperializing or impovershing any other nation or people and in 1/5th of the time.No one else did that, no one else is doing that. Other than you know, the USSR (relative to era)
Also its beyond meaningless when you consider that at most idk 3% of the population of Xinjiang and 1% in Tibet is considering themselves to be occupied by China and are remotely likely to participate or aid in an armed struggle against the CPC, even at the best possible conditions
Like sure, Tibetians have a right to engage in an armed anti-colonial struggle or kickstart an indeginous liberation movement ok. You probably couldnt even fill an NBA stadium with those willing so what does that leave their lib free Tibet dreams. The CIA was trying to recruit and instigate an anti-chinese sessesionist movement last century and they gave up because they couldnt find enough willing Tibetians to get the project off the ground. And they had a budget of dozens and dozens of millions to pay off poor ass Tibetians and they still couldnt find any fertile sessesionist sentiment. And thats on record
