How would you enforce this? In the US this is completely illegal.

In addition, you would have to ask extremely invasive questions of everyone. So is your proposal that you require that your company ask for the detailed ethnicity of everyone? What happens when people refuse, do you just not allow them to interview or manage?

What about people who were born in the US, do you assume that if they are of Japanese descent they can't interview someone of Chinese descent?
