Dubai hosted a meeting that ended on May 24, 2016 of over 100 countries to discuss its plans to host the world Expo trading fair in 2020 which organisers expect to attract 25 million visitors. The meeting is the first since the Emirati city won in 2013 the right to host the event in which Dubai hopes 180 countries would participate, according to a statement by the organisers. / AFP PHOTO / WAM / HOHO/AFP/Getty Images
