Dubai is the largest and most populous 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 development of the city, which was already a major mercantile hub, but Dubai’s oil reserves are limited and production levels are low: today, less than 5% of the emirate’s revenue comes from oil. A growing centre for regional and international trade since the early 20th century, Dubai’s economy today relies on revenues from trade, tourism, aviation, real estate, and financial services.
Dubai has attracted world attention through large construction projects and sports events, in particular the world’s tallest building, the Burj Khalifa. Companies in Dubai have in the past been criticised for human rightsviolations against labourers.
As of 2012, Dubai was the most expensive city in the Middle East. In 2014, Dubai’s hotel rooms were rated as the second most expensive in the world.
Dubai is situated on the Persian Gulf coast of the United Arab Emirates and is roughly at sea level (16 m or 52 ft above). The emirate of Dubai shares borders with Abu Dhabi in the south, Sharjah in the northeast, and the Sultanate of Oman in the southeast. Hatta, a minor exclave of the emirate, is surrounded on three sides by Oman and by the emirates of Ajman (in the west) and Ras Al Khaimah (in the north). The Persian Gulf borders the western coast of the emirate. Dubai is positioned at 25.2697°N 55.3095°E and covers an area of 1,588 sq mi (4,110 km2), which represents a significant expansion beyond its initial 1,500 sq mi (3,900 km2) designation due to land reclamation from the sea.
