Malaysia's Racism issue is pretty complicated. If you check Malaysia education system (It is not like western education), the schools are separated by 'races'. You will find out that only chinks will send their kids to chink schools and study chink language, while the other races will send their kids to other schools (And they won't study chink language).
You can check out some detail information in this wiki, or just find a Chink from Malaysia, and he/she would explain better than me:
