Also now US forced countries to take side and made them drop huawei contracts. So in the future whatever technology products China has on its own has very little upside of selling. Majority of that would be in China domestic market.
US has a strangle hold on many countries therefore the prospect of China become very powerful as time goes by is debatable. Its upside has already been severely capped by US.
This is the US goal, to coerce its vassals to stick to it, to turn away from China and the Chinese market especially as it pertains to anything hi-tech, thereby depriving China of the world market, meaning to make China's tech ascension and tech independence that much harder if not even impossible, and thereby as a consequence with the larger end goal of capping China developmentally to deprive it the ability to get out of the low income trap, so to speak....

To use the game of Go as analogy, maybe (to give the opponent benefit of doubt) the US does have the upper hand, and that US is like AlphaGo and China is running a version of lesser Go AI, so in the end US might still win out in the long run anyway, but the difference would be if China always avoid a fight be it locally or globally it will incentivize the opponent to be more and more greedy and win by many more points than it otherwise would have gotten away with from...
China should do whatever it needs to maximize
