The question is: will Chinese elites adopt Western attitudes towards race and racism? If they do, they too may forbid their scientists from researching HBD, because doing as much will make them appear parochial and uncouth to the greater world community.
Assuming HBD is correct, as the west becomes less white, it will also become less intelligent and hence less powerful, this will mean that the Chinese have less reason to care what the west thinks of them.
You need to make lots of other assumptions, such as no generational Flynn effect stile rises in IQ amng non-white immigrants,
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
