You are not reinforcing any racial stereotype.

Well, there's that thing about the pesky blicks liking to steal/rape and Russian women being whores but... The foreigners in GZ are distinctly non-Western most of the time and they sometimes bring their own savage-baggage from back home. It is better not to beat about the bush and just spit that one out as a heads up to potential GZ FTs.

Still arguably more of a desirable thing than the douchey expat package sleazebags or the French interns that you tend to get in Shanghai though.
