The place Genly ai  comes from is completely different than Gethen.  The first thing that is completely different is the way the speak.  In Gethen they talk in a form that can be taken in multiple ways.  Genly encounters this in chapter one when talking to Tibe the king's cousin.  Genly explains that he can't understand what Tibe is trying to come across because of the way he is smiling a certain way with his teeth.  Another thing that is different are the kind of people present.  In chapter three King Argaven is surprised by the skin tone Genly because he is dark.  King Argaven asks him if the people of where he is from are as dark as him?  This leads me to believe that there are no people in Gethen with the dark skin tone Genly has.  If Genly has a dark skin tone everybody else must be the same or more people with it.  I think the difference from Gethen and from where Genly is from Ekumem is greater than if we to another country. We are shown this when King Argaven ask about the sexual perversion.  Why would he ask about the sexual perversion if they are all people?  This makes it seem like it is a different sexual perversion depending on the locations. What if there is more than just humans that look human that why the king ask Genly about the sexual perversion.  This is a possibility  because the King asks Genly is an alien Envoy.  Of course this is a zoom chance because the word alien can be used and can be interpreted in different ways.  I am just going to stick he refers an alien as someone not from around here.
