I think describing China as one monolithic block in that way is problematic and denies the agency of Chinese people. It is tempting to look at the different political system and lump everything together. You have to distinguish between the government, researchers, and Chinese companies. I know many Chinese researchers who are collaborating fairly, and they have very similar interests and - mixed - incentives as western scientists do. It is true that Chinese companies do what you described, I think at some point there was even an offical slogan for it. But this is just as much due to the "capitalist" side as to the "communist" side. I'm pretty sure if an American company was behind technologically they would do the same. I recall Tesla poaching battery and car manufacturing specialists for example. Not saying that is great, but it would be naive to assume they would do otherwise.
