Excerpts from Books and Wikipedia
"Islam is the official religion and Arabic is the official language of the UAE. The UAE's oil reserves are the seventh-largest in the world while its natural gas reserves are the world's seventeenth-largest. Sheikh Zayed, ruler of Abu Dhabi and the first President of the UAE, oversaw the development of the Emirates and steered oil revenues into healthcare, education and infrastructure. The UAE's economy is the most diversified in the Gulf Cooperation Council, while its most populous city of Dubai is an important global city and an international aviation and maritime trade hub. Nevertheless, the country is much less reliant on oil and gas than in previous years and is economically focusing on tourism and business. The UAE government does not levy income tax although there is a system of corporate tax in place and value added tax was established in 2018 at 5%." [Wikipedia]
