LONDON (Reuters) – Airbus Chief Executive Guillaume Faury warned on Thursday that any further escalation of trade tensions would damage aerospace companies globally, including arch-rival Boeing. The United States has threatened to impose tariffs on a range of European Union goods in a transatlantic row over mutual claims of unfair support for both Airbus and Boeing. “Trade tensions are lose-lose tensions,” Faury told reporters on a visit to London. He said Airbus was using the delay in Britain’s withdrawal from the European Union to “prepare for all scenarios” and reiterated that a no-deal Brexit would be the worst outcome. He also warned of legal action against Germany over a ban on defense exports to Saudi Arabia that has disrupted the implementation of a border security contract with the kingdom.
