Mature and self-made Asian women, especially in the 30-40 age bracket will look for men,
Asian or Western who are at the same or similar level as themselves.

I can only speak from my observations of Chinese society.
Unmarried and divorced Chinese women in their 30s or older, with or without children, have a nearly impossible task to marry financially successful or well-educated Chinese men their own age. These men choose much younger mates. This is fully and painfully documented in Chinese media.
Once again, as they are unable to find more suitable partners, some of these successful 'older' women do choose an interracial marriage.

You are wrong.

I am often wrong, but I do believe there is value in what I have written in the past few posts concerning interracial relationships in China.
I do not possess your 'certitude' about judgements of people, especially in a foreign culture.
