Offer and receive cards with both hands, Vietnamese side facing up if you had a bilingual card printed. Read it for a second or two before putting it away — sliding it straight into a pocket unread is the part that lands as dismissive.
Walk into any meeting and greet the most senior person in the room first, ahead of anyone standing closer to the door or anyone you already know. Save direct disagreement for private conversation rather than raising it in front of the group.
- The same hand you use for the handshake matters elsewhere too — passing dishes at a business dinner follows the same right-hand-or-both-hands rule as the card exchange.
