“We have made clear at every stage that we want to settle this long-running issue. Regrettably, in spite of our best efforts, due to the lack of progress from the U.S. side, we can confirm that the European Union will later today exercise our rights and impose the countermeasures awarded to us by the WTO in respect of Boeing,” Europe’s trade chief, Valdis Dombrovskis, said on Monday. 

The new tariffs will be published Monday afternoon and will come into effect on Tuesday. 

Dombrovskis also said the EU will remove the duties if the United States does the same. “We are not escalating anything, we are exercising our rights,” he added.
