I am sure there are plenty of black people in Liberty tho most would not have an african culture but an American one. Hmm well actualy Liberty probably includes Mexico and Canada also so liberty is probably a big melting pot...go figure.
I would say China should be added if there is another. They are probably one of the most influencial cultures in the world. But they were part of the coalition who all got blowed up along with earth. (I think that is just silly but canon is canon.)
