Dubai: Persian Gulf world expo 2020 Color Smart

Dubai (/duːˈbaɪ/ doo-BY; Arabic: دبي‎ Dubayy, Gulf pronunciation: [dʊˈbɑj]) is the largest and most populous city in the United Arab Emirates (UAE). It is located on the southeast coast of the Persian Gulf and is the capital of the Emirate of Dubai, one of the seven emirates that make up the country. Abu Dhabi and Dubai are the only two emirates to have veto power over critical matters of national importance in the country's Federal Supreme Council. The city of Dubai is located on the emirate's northern coastline and heads the Dubai-Sharjah-Ajman metropolitan area. Dubai will host World Expo 2020. Dubai emerged as a global city and business hub of the Middle East. It is also a major transport hub for passengers and cargo. By the 1960s, Dubai's economy was based on revenues from trade and, to a smaller extent, oil exploration concessions, but oil was not discovered until 1966. Oil revenue first started to flow in 1969. Dubai's 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. As of 2012, Dubai was the 22nd most expensive city in the world and the most expensive city in the Middle East. In 2014, Dubai's hotel rooms were rated as the second most expensive in the world, after Geneva. In 2013, U.S. global consulting firm Mercer rated Dubai the best place to live in the Middle East.
