>But every major US tech company is banned or blocked from competing in China, isn’t it?

Nope, Microsoft operates in China, so does IBM, Uber did before the Chinese branch was acquired by Didi (they weren't banned, just outcompeted).

China is funnily enough even facebook's second largest market by revenue (about 5 billion) from Chinese advertisers.

Google probably could operate in China and I guess doesn't because it fears American backlash.

Doing business in China is arguably more complicated for American tech firms than the other way around, but American companies are most definitely not blanked banned or anything.

That news surprised me. $5 billion USD a year in revenue is a lot of money. Even for Facebook.

They are just printing money from their China business.

Now, imagine if Trump told Zuck that Facebook couldn’t do any more transactions with China. That deserves a LOL..

I'd say more like every websites large enough that won't censor contents towards the liking of the Chinese government for their service within China got banned. It's not an action against companies, but rather websites (as a form of media). Those companies can and are doing business in China, Facebook have sales agencies, Google have multiple offices and sales agencies, while the US quite literally banned Huawei as a company from doing business with anyone in the US.

google, facebook and twitter and any free speech platforms are banned, but non-chinese companies can set up manufacturing I think as long as there is part local control (I think I remember 50% for car companies)

Definitely not a level playing field though.
