Dubai will bid farewell to its spectacular Expo 2020 world fair on Thursday night, leaving a multi-billion dollar mini-city in the desert and heightened expectations for future hosts.
Six months after the delayed opening of the $7 billion, purpose-built site, the Middle East business hub will close the shutters with performances from Christina Aguilera and DJ Tiesto, and fireworks that will go on past 3am local time.
