For Westerners, I think the explanation can go like this. Say you want to do an open source thing, and spend hours on it. Okay.
But if you are in China, you could have used those hours to make money for your family.
Why would you take care of not-family unless you had too much money and time?
I do think the Chinese care about “humanity” in my experience, but Three Body Problem shows a typical version of it: survival of the mass via individual cruelties.
Like I said, though, I think the upside is that the Chinese are naturally unreceptive to anything like rights for AI.
