I was referring to the Chinese diaspora who had left China over decades and even centuries -they had become successful in SEAsia and were often responsible for commercial progress in those places. The sixties were times of conflict all over the world and in SEAsia the Chinese diaspora in those countries found themselves the targets of the frustration of “natives”. I say natives though the Chinese diaspora was born and raised in those countries but were easily identified as being “foreign” in those places.
It means success of ethnic Chinese in South East Asia. In Malaysia, Thailand, etc or even Indonesia, ethnic Chinese tend to be more successful in business circles compared to 'locals'.
