Answer
Cultures
No two cultures are the same and understanding both the social and business culture in another country is the first key to success. Culture defines everything a society does, from its business practices, to its response to advertising and marketing, to negotiating sales. It is important to include research on the culture of the country(s) that you intend to sell to prior to entering their market. Understanding these, often sensitive, areas will mean that you are better prepared when first entering the market. Although the people that you will deal with will not expect you to be completely in tune with the culture, respect and politeness will go a long way.
