I found an interesting article about personal space perceptions between cultures.
It is kind of funny to read although mainly about American and Russian misperceptions about each other due to cultural conditioning about how far away people stand, and other things such as voice volume and facial expressions. Towards the end of the article, it sums up the differences between Russians, Americans, and Northern Europeans:
A problem for visiting Americans is that Russian personal distance lies within an American's intimate distance, just as an American's personal distance lies within northern Europeans' intimate space.
Americans, existing somewhere in the middle, manage to equally offend both parties, for opposite reasons.
To American men, all Russian women appear to be flirting outrageously
On the other hand, many Western men, by using their own national norms for greater distance, little touching, and low eye contact, strike many Russian women as far more "respectful" and "polite" than Russian men.
