BRUSSELS: The European Union has started taking the unpredictability of the United States into account one year after President Donald Trump returned to the White House, EU foreign policy chief Kaja Kallas said on Tuesday.

"Of course, we are allies with America, but we don't really understand their moves recently," Kallas told Reuters in an interview.

"I think it is pretty clear after this one year that the word that we have to take into account is unpredictability. So we are now more calm because we are expecting the unpredictable things to happen all the time, and take it as it is, put some ice in our hats and be calm and stay focused," she added.
