Iran and European planemaker ATR are due to sign a deal next week for the purchase of 20 short-haul passenger aircraft, weeks after Tehran finalized deals with Boeing and Airbus. "Representatives of ATR will come to Tehran this Wednesday to have a final round of talks," Deputy Transport Minister Asghar Fakhrieh-Kashan declared, adding that the contract was worth $400M. ATR is co-owned by Airbus (OTCPK:EADSY) and Finmeccanica (OTCPK:FINMY).
