The same way Chinese tech companies “compete” with Western ones: By not permitting them to do business in China.

They are permitted to do business there. You just have to make a bargain with the devil. 50% of your domestically incorporated branch is Chinese owned. Then you have the requisite technology and IP transfer. Most sensible companies would not accept such a bargain, but you have quite a few investors only interested in the next quarterly profit going up to the right. And they've made that bargain repeatedly.
