last gf before moving to Thailand was Taiwanese, went to USA on a uni scholarship and stayed there 8yrs.
She looked down on just about everyone, maybe Taiwanese get taught about the 'bad Chinese' at school but she had no time for them, Koreans and Malaysians were even worse, Singapore/Hong Kong-Chinese were ok as she described them as 'educated'; never mentioned any of the rest on the list - they were just 'other' to her.
She also had the most irritating accent.
