This is totally simplistic. If you think western journalists are incentivised to criticize basic societal norms and systemic problems, I have a bridge to sell you. I'm also not sure where you're getting these 'hyper-critical' editorials from - where I come from, nearly 150 thousand people just died in a pandemic, and the media has barely said a critical word.
Obviously, in China, they are allowed to criticize even less, but westerners do not read chinese news.
What's more, nor does anybody else.
So the image of China doing very well is not for a lack of bad press. If you read publications about China over the last decade or so, it's a constant slew of doomsaying, and negativity, mostly about problems that turned out to be very surmountable or insubstantial.
The image of China becoming more and more hegemonic is simple: look at their economic growth. Look at the size of the nation. Look at their intellectual culture. China being a very powerful country is a return to a historical norm, and is a totally reasonable development given how big their population is, how skilled it is, and its values.
Meanwhile, the west is seen as falling apart because it is having a massive identity crisis which involved things like the leader of the free world bragging about how big his nukes were on Twitter.
I'm not frankly particularly enthusiastic about China as a world power - I'm not a fan of confucianism, for example, and CCP spokespeople talk like politicians from dystopian sci-fi, but I think it's profoundly wrong to think China is deceiving the world with its masterful press controls. Far from it - the direct censorship and press controls are very blunt mechanisms most states have given up on because they don't work and if you're good at media, you don't need them anyway.
