All business meetings, however informal, are conducted at the office or in neutral venues such as restaurants. Business office hours are usually Monday to Friday 0900-1700, although government departments tend to close earlier. Note that many businesses close down for a religious holiday on Fridays or at least avoid scheduling meetings for that day.

Despite the high humidity levels, suit and tie is the norm for men and smart dress for women, although concessions are usually made for visiting foreign businesspeople unused to the tropical conditions. English is the main business language in Kuala Lumpur, with most businesspeople (at all levels and in companies of all sizes) at least competent in English. Any attempts to use a few Bahasa Malaysian conversational words are greatly appreciated and can break the ice quickly.

One key aspect to remember is that it is considered inappropriate to use the left hand for handshakes or handing over documents, as this is traditionally used for cleaning after toilet use. Business cards are also an essential prerequisite to any business meeting, no matter how informal, and should be handed over with both hands.

Malaysians are quite conservative when it comes to business and clients are not often invited home. As Malaysia is a Muslim country, many local businessmen and women will not drink alcohol during lunch or dinner meetings. However, it is acceptable for non-Muslims to do so, in moderation. It is also important for visitors to be careful when choosing gifts, as obvious things like spirit or wine are a definite non-starter and less obvious gifts like watches, associated with death by many ethnic Chinese, might also offend.
