A day before his summit in Helsinki with Vladmir Putin, Donald Trump identified the European Union as a “foe” – ahead of Russia and China.
Trump was speaking to CBS News at his Turnberry golf course in Scotland, in an interview recorded on Saturday and scheduled for full broadcast on Monday. Asked “who is your biggest foe globally right now”, he said: “Well I think we have a lot of foes. I think the European Union is a foe, what they do to us in trade. Now you wouldn’t think of the European Union but they’re a foe.”
Earlier on Sunday, British prime minister Theresa May said Trump advised her this week to “sue” the EU, as she pursues a Brexit deal.
“Russia,” Trump told CBS, “is foe in certain respects. China is a foe economically, certainly they are a foe. But that doesn’t mean they are bad. It doesn’t mean anything. It means that they are competitive.”
