> They've just not yet really tried to retaliate.

You seem to be pretty uninformed on the matter. It is common knowledge that it is extremely difficult for Western companies to operate in China.

This "retaliation" has been going on for decades. China can't really make it much worse than what they have already been doing for decades.

You're constructing a narrative that puts history on its head. China has allowed foreign firms to come in and exploit cheap Chinese labor. Foreign companies have made enormous profits off of this. Not only do companies like Apple benefit hugely from Chinese labor, but they have also found a market of hundreds of millions of buyers of their product there. Foreign auto manufacturers dominate the Chinese domestic market - VW is the best-selling car brand in China, the world's largest auto market.

You're saying that China has been retaliating by giving foreign companies access to cheap labor and hundreds of millions of customers. That's completely backwards.
