Oh, definitely. There are exceedingly common trends amongst east-Asians (Chinese/Koreans/Japanese) though, as there's a shared lineage there, both genetic and cultural. Take a look at all three countries, as well as the Chinese diaspora. They definitely share similarities on how they treat education.

But my point is, you get an overrepresentation of "Asians" due to the increased focus. This leads to an increased flow of more qualified candidates due to the greater investment from the "Asian" population. The issue for African American underrepresentation is in my opinion, the pipeline, not the admission.
