The chief of Airbus has criticized Poland for cancelling a planned $3.5bn military helicopter contract as which Poland was buying 50 French designed Caracal helicopters.
He said the company had been wronged and will seek compensation. It won a tender to supply the Polish armed forces with helicopters in April 2015.
The reaction from France, where Airbus Helicopters has its headquarters, and where the Caracal has been designed and developed, was swift. President Hollande had been due to visit Warsaw for talks this week, but his visit has been cancelled.
Poland blamed Airbus for the breakdown in negotiations, suggesting it failed to offer adequate incentives in exchange for the contract.
However, in an open letter to the Polish prime minister published on Tuesday, Airbus rejected that claim.
