Timeliness is important in business circles; thus, arriving after the arranged time without informing can be disrespectful to your business counterpart.
The formal customary salutation is the nop; however, this tradition can be replaced in business circles with a handshake.
In Laos, foreigners are expected to handshake the people they meet, notwithstanding gender.
The exchange of business cards with everyone during the first meeting is a business tradition, and subsequently when introduced to new business contacts. So, make sure you have a steady supply on hand.
At business meetings, respect is bestowed on the senior-most individual in the organisation. Thus, primary communications should be addressed to them as the decision maker, unless stated otherwise.
Decision-making may take substantial time as communication and information get relayed through the organisation's many channels, particularly with the hierarchy.
Meetings are not rigid and do not follow strict schedules. Discussions will go on until all present feel everything is settled satisfactorily.
Bargaining is the norm, and expected in commercial dealings in Lao culture, although they are gentle bargainers.
It is most important to check the transparency of ideas and statements if uncertain of the intention of what is being conveyed. People of Laos tend to use the phrase 'yes' to many things and may connotate different meanings. But know that it doesn't always mean an agreement is conclusive.
