Why was the progress of China hidden from Indians so far ? Are majority Indians anti technology and anti progress ?

Recently we are seeing vlogs and Indians are realising that China was making progress from last 50 years by becoming factory of USA ? Bullet trains, metros. By 2010, they had more than 5000 kms of high speed trains running at 300 kmph. More than 2500 kms of metro lines in 12 cities. And now it's more than 25000 kms of high speed and 45000 thousand kms of metros in 45+ cities.

Development in building bridges, own brand electronics, cars, phones etc. In everything.

Definitely there are some difference between them and us. Communism, size of country etc.

But never governments or media told us how much China was doing progress. We were only making fun of Chinese - snake Eater, cockroach eater, etc.

I am not even thinking same level of new age things. But many things are really necessary. Like progress in education, healthcare and transportation. But that also we are still not catching pace and speed.

Why ?
