Omar Al Zawawi wears many hats. The business tycoon is the special advisor for External Liaison to Sultan Qaboos Bin Said, the ruler of Oman, and the chairman of Omzest, one of the sultanate’s largest diversified groups. Al Zawawi was also the founding chairman of Muscat Finance, and under his leadership, Oman International Bank, part of Omzest, merged with HSBC last year.
