The new chief executive of Airbus, Guillaume Faury, says the company will "probably" have to take legal action against the German government over its effective ban on arms sales to Saudi Arabia.
In November, Berlin said it would stop granting export licences for sales to the Saudi kingdom.
The embargo was introduced in the wake of the murder of journalist Jamal Khashoggi at the Saudi consulate in Instanbul last year, and Airbus has already said that it is affecting its business, because a number of the aircraft it sells contain German parts.
Speaking to journalists in London, Mr Faury said Airbus had contracts with its customers and needed to "defend our own contractual obligations and interests". He added that it was close to taking action in "a number of cases".

Airbus has posted a €40m profit for the first quarter of 2019 - an 86% drop on the same period last year.
Among other things, it blamed "the prolonged suspension of defence export licences to Saudi Arabia by the German government" for the drop.
However the European aerospace giant registered strong revenue growth at €12.5bn, boosted by higher commercial aircraft deliveries.
