(ANSA) - Rome, January 21 - Tourism at Expo 2015 is expected to generate 5 billion euros of revenue, said Expo CEO Giuseppe Sala on Wednesday.
    Sala said the number is realistic given that 20 million people are expected to visit Expo 2015.
    "It's the number I like the most, together with that of participating countries' foreign investments of around one billion euros, of which 90% has gone and will go to Italian businesses," Sala said.
    With just 100 days until the world's fair opens, Sala was visiting Rai headquarters to present the February 7 "Expo of Ideas" event, where over 500 people will meet at the Hangar Bicocca art museum in Milan to draft Expo's Milan Charter.
    Sala said plans are already being made about what to do with the various Expo sites once the fair ends in October.
    "The commitment is to dismantle everything by June 2016, but before that date I'm sure that solutions will be found so as not to abandon the area," Sala said.
