Personal Space is Sacred
In the movie "Dirty Dancing", Frances "Baby" Houseman, played by Jennifer Grey, pointed out that about a foot of air space between her and Johnny Castle (Patrick Swayze) differentiates what is YOUR dance space from what is MY dance space.
This is on the border of what anthropologist Edward T. Hall would call your Intimate Distance (0 to 18 inches / 0 - 46 cm for personal touching and embracing) and the close Personal Distance (1.5 to 4.5 feet / 46 - 76 cm for interactions with friends and family members). I sometimes wonder how society has changed - only 100 years ago dancing was the closest someone single could get to someone of the opposite sex without causing a scandal. There was touching, closeness, and the opportunity to exchange sweet nothings. Today, dance floors look more like someone let loose a bunch of electric eels. Where's the charm? Where's the human interaction? But I digress.
Back to personal spaces, and how they are interpreted differently across cultures
What in the West is reserved for family in friends is often fair game among strangers in Asia.
What we consider Social Space (4 - 7 feet / 1.2 - 2.1 meters for interaction with acquaintances and colleagues) would be considered too impersonal.
In Western society we try to compensate and create other barriers when we feel like our personal space is violated. That creates stress, so to compensate, we avoid eye contact and smiling is rare e.g. on crowded public transportation.
When doing business with nationals whom you feel are "invading" your intimate or personal space, resist the urge to take a step back.
Well, only if you want to do business together. Why?
A), they may take a step forward to be closer to you again, or - worse -
B), they may consider your creating physical distance as a sign that you're not trustworthy.
Eye-contact is similar - in some cultures, mainly Northern and Western, it indicates trust and paying attention. In others, mainly Eastern and Southern, it is a non-verbal sign of equality, e.g. younger people would not look their elders in the eye, nor would it be culturally acceptable for women to look directly at men.
Various researchers have found more gender differences:
(1) Women smile more than men.
Burgoon, Buller, & Woodall, 1996
(2) Women stand closer to each other than men do and are generally approached more closely than men.
Eakins & Eakins, 1978
(3) Both men and women, when speaking, look at men more than at women.
Pearson, West, & Turner, 1995
(4) Women both touch and are touched more than men.
(5) Men extend their bodies, taking up greater areas of space, more than women.
