My mostly uninformed speculation would be that it might be tied to the entire model minority thing. As far as many minorities are concerned, asians are treated way better by white people and are doing better. Wouldn't be surprised if it has to do with a combo of othering and jealousy. But I'm not informed on that front, alas.
Eh, I wouldn't say Asians are treated better than any other minority. Model minority also carries the expectation of submission, so any Asian person who is remotely seen to be independent is automatically shunned or brushed off in Western culture, unless there was an overwhelming symbol of status or power.
