The world's biggest commercial aerospace and civil aviation exhibition is set to return next year after Hong Kong beat off fierce competition from mainland cities. For the second time in a row, the two-yearly Asian Aerospace International Expo and Congress, which saw the the staging of a low swoop over the harbour by a new Airbus A380 last September, will take place at AsiaWorld-Expo in September 2009. Allen Ha, CEO of the exhibition centre, hailed the return as a significant boost for Hong Kong's exhibition industry and an indication that its prospects remained healthy despite fierce regional competition. The aviation expo had been a prized possession of Singapore. Major events coming this year include the China Sourcing Fair, between April 12 and 23. It was previously held in Shanghai before coming to AsiaWorld-Expo in 2006. AsiaWorld-Expo announced the list of confirmed events amid increasing competition, notably from the Venetian Macau's 100,000 square metres of exhibition space.
