Since these two[1][2] incidents, I wondered deeply for a while, what is going to happen here as it seems the CCP is getting more and more brazen. I don't believe it would be legal for "enhanced background checks" on someone in the hiring process because they are Chinese American, and it opens an awful door regardless. I don't really know the solution, but I've thought a lot about the problem. (And yes, of course there is that 5 eyes/other "Western" powers are almost certainly doing similar stuff)
