You will make a good impression if you respect the language
The official language of most Arab countries, including Saudi Arabia, is modern standard Arabic. Saudis are very proud of their mother tongue, so knowing the fundamental Arabic greetings will impress them.
We recommend that you learn some of the most useful phrases for any occasion, but if your business partners would prefer to lead a meeting in Arabic, hire an interpreter. This will demonstrate that you are serious about doing business with them and that you respect their language.
Meeting handshakes are common even in the Arab world, but they usually take a little longer than we are accustomed to. So, instead of withdrawing your hands immediately, wait for your Arab business partner to do so. If you do business with women, keep in mind that some of them are still very conservative, so you should wait for them to offer you a hand on their own. Also, wait for a handshake if you do business as a woman in the Arab business world of men.
Saudis typically conduct business in formal settings, so address them with Ms or Mr in front of their name, though this varies by country.
If you want to do serious business in the Arab world, you should print your business cards in both English and Arabic. Because the language is read from left to right, place your company logo on the left side of the card.
