US planemaker Boeing
The World Trade Organisation's appeal body handed down a final ruling on Monday that found that subsidies and tax breaks to US planemaker Boeing caused serious prejudice to
its European rival Airbus.
"In completing the analysis, the Appellate Body found that" subsidies and tax breaks "caused, through their effects on Boeing's prices, serious prejudice in the form of significant lost sales" to Airbus in the market for civil aircraft with 100-200 seats, according to a summary of the 700-page ruling.
That segment is for the medium-haul Airbus A320 and Boeing 737, which are their top selling aircrafts.
The WTO appeals panel reversed a number of findings from the initial ruling March 2011, saying that tax breaks provided to Boeing from the US state of Washington and the city of Wichita, Kansas magnified other subsidies and caused price effects that caused lost sales.
