Asian communities face less discrimination from the white community as there hasn't been a lot of reinforcement of negative stereotypes relating to any of the Asian communities. Compare that with the history and treatment of the black community and you can trace a direct line from slavery to where many communities are today. A lot of propaganda regarding black people had been fed to whites for hundreds of years in order to justify their enslavement.
The black community has seen Asians as a "preferred minority" who has benefited from their civil rights work and at the same time given opportunities they didn't have without giving back to black communities.
There is a lot of nuance in there, but that's the super short version.
