The UAE economy was managed by palm cultivation, fugitive farming, fishing etc before the discovery of oil. Having the most diversified economy in the GCC, the economy remains subservient to petroleum. UAE's oil exports were more than 85% in 2009. In the economy, a significant role is played by both petroleum and natural gas, especially in Abu Dhabi. Most of the UAE depends on oil revenue, except Dubai. With a dollar 350 billion active construction projects, UAE has the world's most luxurious hotels. Tourism plays a major role in its revenue, due to this cause.

The country became a major part in the growth by 20th century by the previous UAE President Zayed Bin Sultan Al Nahyan. His intelligence in converting the revenue from oil exports made the development possible. After the crisis of 2007-2010, Dubai owed a $142 billion debt in 2014. As a means to reduce the country's dependence on oil exports, the government has introduced various projects like the Khalifa port of Abu Dhabi and the World Expo of 2020.
