Whiskey or cognac is an appropriate gift for business. Handkercheifs are symbols of a sad farewell, and most Asians think using a cloth handkerchief and then returning it to one's pocket is uncivilised. Never give knives or scissors, as these objects can be considered aggressive. Never give someone a gift which contains a set of six or 10 objects as these numbers are considered as unlucky in Vietnam. Do not give anything that is an owl or has an owl pictured on it.
Owls are an omen of death in Vietnam.
Never wrap gifts in black or white paper as such colours are considered inauspicious in Vietnam, always wraps a gift in colourful paper. Red and Gold colours are good for gifts as they symbolised good luck.
