Dubai is the largest and most popular city in the United Arab Emirates(UAE). On the southeast coast of the Persian Gulf, it is the capital of the Emirate of Dubai, one of the seven emirates that make up the country. Dubai is a global city and business hub of the Middle East. It is also a major global transport hub for passengers and cargo. Oil revenue helped accelerate the early development of the city, but its reserves are limited and production levels are low: today, less than 5% of the emirate's revenue comes from oil. Dubai's economy now relies on revenues from tourism, aviation, real estate, and financial services
