When we enter into a negotiation, we are facing a number of different  challenges. 

One of the biggest can be cultural barriers to communication  if the other side comes from a different background than you do. In  order to overcome such issues, we need to find different ways to use our  negotiation styles and negotiating techniques to communicate with the  other side using manners, body language, and perhaps even our physical  appearance. When we are negotiating with someone online, a number of the ways that we communicate will not be available to us. 

However, we are still going to have to find a way to build a sense of rapport with them.
