China’s one child policy was to combat explosive population growth as well as the reactionary habit of having many children as a store of wealth. Ethnic minorities in China are mostly from regions where there is not an abundance of food and thus they had lower reproduction rates to begin with.

Birth rates don’t even hit replacement levels in settler states. Explosive population growth is not a issue at all. Indigenous peoples already have higher than average birthrates in the 3 big settler states.

Its a “fix” for a problem that doesn’t exist done for eugenics purposes.
