The World Trade Organization on Monday rejected European Union claims that it no longer provides subsidies to planemaker Airbus, underscoring tariffs recently imposed by the United States on European goods.
A new compliance report from the Geneva trade watchdog found that the Airbus A380 and A350 jetliners continue to be subsidized as a result of past European government loans.
It is the latest move in a record transatlantic trade dispute involving mutual claims of illegal aircraft subsidies, which comes to a head at a time of rising global trade tensions and has grabbed the attention of financial markets this year.
The United States was in October awarded the right to impose tariffs on $7.5 billion of annual EU imports in its case against Airbus. It went ahead with partial tariffs on most Airbus jets and products from cheese to olives and single-malt whisky.
A decision on retaliation rights for the EU in a parallel case on aid for Boeing is due next year.
Officials on both sides have expressed support for a negotiated settlement, while accusing the other of failing to take the prospect of a negotiated solution seriously.
In Monday’s finding, a three-person panel rejected EU claims that a recent decision by Airbus to stop producing the slow-selling A380 meant the giant airliner could no longer be seen as a threat to Boeing, whose competing 747 is also out of fashion.
While the WTO no longer faulted Airbus for causing lost sales to Boeing with the A380, which is no longer marketed, it ruled that the superjumbo would cause market-share damage to Boeing for as long as it is produced and delivered.
Airbus plans to shut production in mid-2021.
The WTO appeared to strengthen findings against the A350, saying it had both cost sales and damaged Boeing’s market-share prospects - a process called impedance - in the busier twin-engined long-haul market where Boeing offers its 787 Dreamliner.
A previous WTO ruling had focused only on lost sales.
The latest report put the world’s largest corporate trade dispute squarely on the agenda for new EU Trade Commissioner Phil Hogan, who started his term on Sunday.
The Commission said the new findings contained serious legal errors and that it would consider its next steps, including a possible appeal, while seeking an accord with the United States.
There was no immediate comment from the U.S. Trade Representative.
As so often following the dozens of rulings in the 15-year-old trade case, Airbus and Boeing were left starkly at odds.
Boeing claimed a complete loss for its European rival Airbus, which it said continued to harm the U.S. aerospace industry by receiving billions of euros in illegal aid.
Airbus said the WTO’s decision to drop previous references to the A380 causing lost sales to Boeing meant the United States should slash its authorized tariffs by $2 billion to $5.5 billion.
U.S. sources said only full compliance or a political settlement - which is widely seen as remote amid fragile economic ties - could legally cancel WTO approval for tariffs.
European executives warned against a “lose-lose” trade war.
Both sides can appeal the latest finding but doing so could place the WTO in uncertain legal territory, experts said.
The WTO Appellate Body will cease to function after Dec. 10 due to U.S. blocking of new appointments, leaving a tight deadline to challenge Monday’s ruling.
Any appeals launched after that date risk falling into a legal void, while it remains unclear whether the body will be allowed to rule on appeals filed before then.
