HELSINKI (Reuters) - On the eve of his meeting with Russia's Vladimir Putin, U.S. President Donald Trump rattled allies once more by labelling the European Union a "foe" with regard to trade.
In a pre-summit interview with CBS News' "Face the Nation" programme aired on Sunday, Trump lumped in the EU with China and Russia as U.S. economic adversaries. "I think the European Union is a foe, what they do to us in trade," he said.
Trump and Putin will meet on Monday in Helsinki for their first stand-alone meeting since Trump took office in January 2017. Trump arrived in Helsinki on Sunday evening after spending the day playing golf at his private club in Scotland.
The Helsinki summit, which comes at one of the most crucial junctures for the West since the 1991 fall of the Soviet Union, has alarmed some NATO allies who fear Putin might seek a grand deal that would undermine the U.S.-led transatlantic alliance.
During last week's NATO summit in Brussels, Trump repeatedly criticized other member countries for failing to spend more on defence, and openly questioned the alliance's purpose.
In recent months, he has also been highly critical of the EU in trade terms, arguing that its policies make it difficult for U.S. exporters.
After Trump labelled the EU a "foe," Donald Tusk, president of the European Council, responded on Twitter, using one of Trump's favourite stock phrases.
"America and the EU are best friends," Tusk wrote. "Whoever says we are foes is spreading fake news."
Trump and his aides have been working through the weekend to soften expectations for tangible results from the Russia meeting.
"I go in with low expectations," Trump told CBS.
John Bolton, Trump's national security adviser, said in an interview with ABC's "This Week" that the United States would not be looking for "deliverables" and that the meeting would be "unstructured," beginning with a one-on-one session between the two leaders.
The U.S. Ambassador to Russia, Jon Huntsman, told NBC'S "Meet the Press" that the meeting was "an attempt to see if we can defuse and take some of the drama, and quite frankly some of the danger, out of the relationship right now."
A probe over allegations of Russian meddling in the 2016 U.S. presidential election has clouded Trump's presidency. Trump has denied any collusion with the Russians by his campaign and Russia denies it meddled.
For Trump, the formal meeting with Putin is an opportunity to develop a closer working relationship with the Russian president.
They have met twice before on the sidelines of international summits. Last November, in Vietnam, they agreed to maintain open military channels of communications between their forces in Syria.
Trump has baffled his own advisers at times with his unabashed desire for strong ties with Putin, White House sources have said. Most U.S. officials see Putin as an unsavoury character on the world stage.
U.S. officials have said they hope to make progress during the talks persuading Russia to use its influence to get Iranian forces out of Syria, as part of a wider campaign to rein in Iran's influence in the Middle East.
They also expect Trump to bring up Russia's incursion into Ukraine and the allegations of Russian meddling in the election. Other issues include the potential for nuclear arms talks and North Korea's nuclear challenge, given that U.S. officials have said Russia had worked in the past to help Pyongyang circumvent international sanctions.
Huntsman on Sunday said that it was "highly unlikely" the United States would recognise Russia's 2014 annexation of Crimea, but would not rule it out.
German Foreign Minister Heiko Maas has warned Trump against making any unilateral deals with Russia that come with a cost for the United States' Western allies.
ALONE IN THE ROOM
The meeting comes just days after 12 Russian intelligence officers were charged by a U.S. federal grand jury for hacking the Democrats ahead of the 2016 election, the most detailed U.S. accusation yet that Moscow meddled in the election to help Trump.
When asked by CBS if he would ask Putin to extradite the Russians to the United States, Trump said he might. Russia's constitution forbids the extradition of its own citizens.
"I hadn't thought of that," Trump said. "But certainly, I'll be asking about it."
The top Democrat on the Senate Intelligence Committee, Mark Warner, said he was worried about Trump being alone in the room with Putin, without his national-security aides.
"We know that Trump doesn't do a lot of prep work for these meetings. He kind of goes in and wings it," Warner said on NBC's "Meet the Press. "I really would feel much better if there were other Americans in the room."
The president has repeatedly said the investigation into Russian election meddling is a "rigged witch hunt" that makes it hard for him to do substantive deals with Moscow.
