Cambodian attractions are unique to its culture and history making things to do in Cambodia a real Khmer experience. Most people to Cambodia are lured in by the impressive ancient temple city of Angkor in Siem Riep. Once hooked, Cambodia strings tourists through more recent history of the Khmer Rouge. The sombre Phnom Phen attractions such as the killing fields and Tuel Sleng prison museum are in contrast to the vibrant Central Market and to the relaxation of the river front and lake side.

For even more relaxation travellers may slide down to the beach towns of Kep and Sihanoukville on the Cambodian coast. Others enjoy the unique Irrawaddy river dolphins of the north east. Bus is the most common mode of transport between attractions and is muddy travel in monsoon season June to October and dusty the rest of the year.

Developing a personal relationship in Cambodia is important before any business can be discussed, which might include long dinners and plenty of socialising. Never cause a Khmer to 'lose face', but use tact and an indirect approach to business. On introductions, the most senior in the group will be introduced first, and visitors are advised to do likewise so that the hosts understand the hierarchy of the group; the highest-ranking person on both sides should greet each other first and perform the introductions. A light handshake is appropriate on introduction, after which business cards can be exchanged using both hands; it is considered impolite to put the card away without making a show of studying it for a short while. In Cambodia people are addressed with the honorific title 'Lok' for a man and 'Lok Srey' for a woman followed with the first name or both the first and surname. Dress is conservative, but formal business suits will be out of place in the tropical heat; lightweight suits can be worn for formal meetings. Business hours are generally 8am to 5pm Monday to Friday, with a long lunch from about 12pm till 2pm.
