GENEVA Nov 28 The World Trade Organization
(WTO) ruled on Monday that a tax break from Washington state to
help U.S. planemaker Boeing develop its new 777X jetliner
was a prohibited subsidy.
The WTO said the subsidy came in the form of a renewed cut
in the state's main business tax for aerospace agreed in 2013,
when Boeing was considering where to base assembly of the latest
member of its long-haul jet family.
It rejected a complaint by the European Union against six
further tax measures.
It is the third swathe of public support for Boeing or its
European rival Airbus criticised by the WTO in a record
transatlantic trade dispute dating back 12 years, and involving
mutual accusations of tens of billions of dollars of aid.
The ruling, which can be appealed by either side, comes as
the United States ponders potential sanctions against the EU
over earlier WTO rulings against Airbus.
