The International Air Transport Association (IATA) has said the seventh World Cargo Symposium (WCS) is to be held in Doha, Qatar, from March 12-14, 2013. The event, which will explore the theme of 'Action for Sustainability', will be hosted by Qatar Airways. Around 1,000 air cargo decision-makers are expected to converge on Doha for the WCS. "All eyes are on the Middle East. The region's double-digit expansion in cargo markets over recent years has seen it grow to now account for over 11% of air freight. Holding the event in Qatar will shine a spotlight on the economic benefits that flow from an enlightened government supporting growth with low taxes, efficient regulation and infrastructure to accommodate growth," said Des Vertannes, IATA Global Head of Cargo.
