The Koreans aren't concerned about how well planned a meeting is. They will not trust anything that doesn't take years to build. For example, a strong relationship of 10 years is more important than a brand new office building or an impressive meeting. Trust is the most important thing for them. They also seldom offer any opinions unless they are sure about what they want to say.
Face is perhaps most important to the Japanese. For example, if you put pressure on a Japanese businessman at a meeting, he will respond with silence and your relationship is sure to be over even before the meeting finished. They will be more accepting of you if you learn to speak a little Japanese and look comfortable with their customs.
Whenever there seems to be a business problem, the British will try to improve the situation by saying something amusing, but sometimes others don't find this humour funny at all.
Whenever you disagree with the French, they will enjoy arguing with you in a very lively way. They will offer you a business opportunity more quickly than people from other cultures, but they will change their minds at the last moment, if they feel that you are not doing business in a satisfactory way.
