Difference between discrimination and differentiation, aba

Discrimination refers to purposely creating an unfair treatments or  negative outcome for a certain individual solely because of that person's race. (example: not hiring you because you are minorities)
Differentiation on the other hand creating an unfair treatment but because we really need it (for example, not hiring someone who is hispanic because we need someone who could help mediate the company in chinese market)
