The World Trade Organization (WTO) ruled on Monday that the European Union has not completely eliminated its subsidies to Airbus.Boeing CoThe negative impact. Airbus A380 and A350 jets continue to be subsidized because of past European government loans, according to a new compliance report by the Geneva Trade Surveillance Agency (Geneva trade watchdog).

This is the latest development in the record transatlantic dispute.

According to previous reports, after the WTO ruled that the European Union subsidized Airbus, its dispute settlement body formally authorized the United States to impose tariffs on 7.5 billion dollars worth of products imported from the European Union into the United States.

In Monday's ruling, a three-member panel of WTO rejected the EU's claim that Airbus recently decided to stop production of its slow-selling A380, meaning the jumbo jet is no longer seen as a threat to Boeing Co and the Boeing 747 is out of date. Airbus began developing super-large airliners in the 1990s to compete with Boeing 747, which carried the highest number of passengers at that time.

Although WTO no longer believes that the A380 that Airbus is no longer selling has caused a loss of sales to Boeing Co, it has ruled that the superjumbo will continue to hurt Boeing Co's market share as long as the A380 is still in production and delivery.

Airbus plans to stop production of the A380 by mid-2021.

The WTO ruling appeared to reinforce the findings of the A350, saying it affected both Boeing Co's cost sales and Boeing Co's market share prospects for Boeing 787 Dreamliner in the busy twin-engine long-haul aircraft market.

The European Commission said it had taken note of the report, adding that there were some serious legal errors.

The US trade representative had no immediate comment.
