It's impressive for exactly the same reasons. It's hard to foster an intellectual elite in a dictatorship, to maintain motivation and cooperation across a gigantic country and 1.7B of people.
Beside, we did the same: polluting, forcing population to work, etc, only 100 years before, but we attacked other countries while doing so. Which China haven't. And about this pollution thing, they seem to correct trajectory faster than we did, given their timeframe and inertia.
It's amazing to watch.
