US companies have a massive presence in China, utterly unmatched by the presence of any Chinese company in the US. It now looks more and more like large Chinese tech companies, on the other hand, are de facto banned from the United States. The most egregious case is Huawei, which the US not only banned from its own market, but is actively trying to destroy through sanctions. The US is even threatening foreign companies with sanctions unless they stop doing business with Huawei.

Has China ever done something that drastic to a US company? What $120-billion-revenue, 200k-employee US company has China ever sanctioned out of existence?

The striking thing about this trade war is how little China has retaliated against American companies. China could savage a lot of American tech companies that profit massively off the Chinese market. But the Chinese government appears to hope that the US will come to its senses at some point, and is therefore holding off for the moment.
