it's probably more complicated than simply showing her a few good points about asian culture.
If you think the problem is with asian people then the most logical solution would be asian people.
if you have any asian friends maybe you can introduce her to them. get her to get to know some nice asian people, maybe she'll change her opinion.
honestly though she sounds kinda close minded about it. If someone dislikes an entire race of people you'd think there would be a damn good reason for it, and not just because she "dosent get along with any asian people at her school"
maybe there is another reason that you don't know about, talk to her about it.
