For me it is OK, I have nothing against it.
Just like Dan has already told you, it's more the question of personality, not the country.
If the person is good, then it's not going to be a problem for him/her to share the room with a Chinese, Japanese, Latin American, etc
The skin is less important because in the God's eyes, we're all the same.
I hope my answer was helpful.
If you have any questions more, feel free to ask me.
