The priority of the Chinese government is the benefit of its citizens (leaving aside that the CCP doesn't consider ethnic minorities in China to be full citizens, as this is a separate issue) and its domestic economy, not the benefit of the American tech sector's senior executives and shareholders.
It's not reasonable to expect, much less demand, that the Chinese turn their tech economy over to silicon valley by allowing unrestricted US entry. It's not in their economic interests, nor is it in their security interests, and no amount of US bullying will change this.
China is not Europe; it's not going to hand over the keys to its economic future to the United States just because the US asks for them.
