The World Trade Organization (WTO) has ordered that more than 20 billion dollars in US government subsidies should be withdrawn from Boeing. According to agency reports, a confidential interim report released on Wednesday is said to back European complaints over 17 billion dollars in research contracts from NASA and the Pentagon. Another 4 billion dollar tax breaks came from Washington State.Nefeterius McPherson, a spokeswoman for the US Trade Representative's Office told BBC that the report is confidential. The WTO report on Boeing was prompted by complaints from the European Union which argued that Boeing was being given support that was anti-competitive. European Trade Commissioner Karel De Gucht said the report backed the E.U's case and some of the findings of the WTO Panel Report on subsidies to Boeing have already been leaked and commented upon.
