What keeps us away from doing business with Russian companies ?

I am interested to know what most of the Western European companies keeps away from doing business with a company from Russia.

Western European companies try to do their business in Russia for many years with success but it seems to be a one way street.

If all the necessary product qualities, services and language barriers are at least equal to our West European standards what keeps us away from doing business with Russian companies.

Do we have some kind of prejudice or do we elevate ourselves above other countries( consciously or unconsciously ). Are we afraid to jump into the unknown ? Is it a cultural barrier ? Do we still think that we will be punished by other countries for doing this business ? Or is it just a gut feeling based on ……

You would be surprised to find out the high quality and knowledge coming from this country which is sometimes better as our standard. (do we want to know this anyway ?).

Ending with my question : what keeps us away from doing business with Russia?
