Acceptable Public Behavior

Tone of voice and body language is less expressive than in southern countries and North America. This should not be interpreted as a lack of interest.
Interrupting a Scandinavian speaker is considered rude.
Be careful with culture related jokes unless they are self-depreciated. You will notice that Danes have a brotherly relationship with Norwegians and more of a love-hate relationship with the Swedes.

Business Attire

Dress conservatively. If the host opens a bottom in his/her shirt, you can follow.
Men should wear suits, ties and well-kept shoes.
Women should wear stylish yet modestly suits and pumps. Pantsuits are also acceptable for women
Khakis are not acceptable business wear. Informal is considered to be jeans with a shirt or blouse. Women should not wear sneakers to work.

Business cards can be exchanged after a short small talk.
Let the Scandinavian counterpart set the stage for how to address each other. Usually Danes and Norwegians are less formal than Swedes.
Use moderate, steady eye contact.
Be aware of the fact that Scandinavians are reserved and low-contact people who do not engage a lot in physical contact.
Build trust by being honest and well-prepared. “New” is not necessarily better. New concepts need to be proven as high quality and should already be well-tested.

Women and men are generally treated equal in business matters.
A meeting starts with shaking hands. Use a firm grip with everyone in the room when you arrive and before you leave.
Scandinavians like to get things started right away. Do not spend too much time on small talk, but get straight to business.
Facts and figures are crucial. Presentations should include handouts and colorful overheads or Power Point slides.
Scandinavians are people of their word. Once an agreement has been signed, you can be certain that the project will move forward.

Always arrive on time.
Do not discuss business during the meal.
Always leave some food on your plate. A clean plate indicates that you were not given enough food, and this is a huge insult.
Leave some tea in your cup if you do not want a refill.
Slurping and belching at the table can be perfectly acceptable.
Chinese people enjoy testing the ability of a foreigner to handle his or her alcohol, so be ready to drink.
Do not tip. It is considered an insult.
The person who invites pays the bill. However, you can make a slight effort to pay, but do not insist.
Toasting is an important part of the Scandinavian culture. Raise your glass to mid-chest height, look the host in the eyes, drink, lower the glass and look in the eyes again, and then put the glass back down on the table. The Scandinavian word for “cheers’ is ‘Skaal”.
It is not uncommon for Scandinavians to invite business contacts to their home. You will normally be told to come between 6.30pm and 7.30 pm. Do not come late!
It is a good idea to bring a small present to the hostess e.g. chocolate or flowers.
When the meal is over thank the hostess by saying: “Tak for mad”
It is considered good behavior to call the following day to say that you enjoyed the dinner the day before.

Avoid excessive gift giving. Scandinavia is one of the least corrupt places in the world. They may perceive this as bribe.
If you ask: “How are you?” Scandinavians will take this question much more serious than North Americans. Instead, use phrases as “Good morning”, “good evening” or “Nice to see you”.
