As Airbus could lose $12bn in orders, Gallois announced EADS reported a 72 per cent increase in profits for the fourth quarter to $810 million.
Speaking to the Associated Press news agency, he said 35 orders by Chinese airlines for A330 aircraft are on hold because China's government is refusing to approve them.
He said orders for another 10 A380 superjumbos are also under threat, and that the combined list prices of the aircraft is $12bn.
