You can't get them if you are Chinese Citizen with a H1B.
I have looked up 5 AI researcher job and all 5 needed government clearance.
The problem I see is that for now, Most field of research in China would require to re-invent the wheel, when the west stopped sharing their secret with the Chinese, they are going to need to devote some time to level the playing field first.
That's a side problem for China refusing to let foreigner work in sensitive technology. I mean you will see Russian-American or Chinese-American who works in sensitive field in the US, but you probably won't see American-Chinese or British-Chinese working on Chinese research in large quantity.
