Look at TikTok, DJI etc. It's not that simple. Also the reason US companies are in China is because it is worth it for them, trust me.
You also seem to be forgetting the tech/software dominance the US has around the world.
But in principle I agree with you, this should of course include the US closing its bases outside of its own territory. Why? Because if you want to have bases on someone's territory so that you can protect your economic interests you have to offer something of value in return. If not, why should you have the right to stay?
As for SA, they're trying to kickstart their own industry as a relatively poor country, same as India. Guess what? The US was extremely protectionist when it was building its own industry.
The example about the cars is also outright false, the Tesla Shanghai Gigafactory for example is 100% foreign owned.
The only true statement you made was that you can't sell video games in China without a local publisher. Even so, I doubt the U.S. allowing foreign citizens to sell games without a local partner is the sole basis for your "We need to protect local businesses with protectionism!" argument.
not quite. it depends on the industry. there are certain industries -- telecom being one of them -- where a JV is required
also, your company is not a regular company, but in a special category and subject to other restrictions that a Chinese-owned or JV isn't subject to
it's easiest in manufacturing especially if you have a company that is basically manufacturing for export
it used to be very difficult, but it's gotten easier in recent years; but it's very different than having a business in the US that is foreign owned
People could complain, well you can do that because you’re the biggest market. We need to protect local businesses. But the USA can go protectionist too. We’re all going to end up paying the protectionist tax.
