"Europe is facing tariffs today because Airbus has refused for years to comply with WTO rulings," Boeing said in a statement.
"Yet even today, Airbus could still completely avoid these tariffs by coming into full compliance with its obligations. We hope it will finally do that.”
The European Union has launched a process at the WTO aiming to show that it has complied with earlier rulings on Airbus, but WTO arbiters refused in a report published on Wednesday to force Washington to await the outcome of this before imposing tariffs.
Airbus earlier called for talks to ease the long-running two-part dispute over subsidies to both Airbus and Boeing.
