In a statement, Greer expressed frustration that despite "ongoing requests", his office has received no details about the US$3.4 billion loan made in June from the EIB, the EU's official lending arm.

US planemaker Boeing had asked the US government in July to press for transparency on the loan, which came amid speculation that Airbus would use the funds to develop a new aircraft model.
