Trump singled out Germany on Wednesday when he accused them of being "totally" controlled by Russian Federation because Russia provides a large share of their oil and natural gas.
The mercurial tycoon said before leaving Washington that his meeting in Helsinki with Russian President Vladimir Putin on Monday "may be the easiest" part of his European tour, which also includes a trip to Britain, where the government is in crisis over Brexit.
The unusually harsh assessment from the country's former top diplomat came after Trump said at a breakfast meeting in Brussels that he considers Germany to be "captive to Russia" because it is getting much of its energy from the nation and continued his attacks on other allies for their levels of defence spending.
German Chancellor Merkel hit back immediately, not only denying Trump's contention but suggesting that his comfortable upbringing in the USA gave him no standing to spout off on the world stage about Germany. "And I am very happy that we are today unified in freedom as the Federal Republic of Germany", she said in an arrival statement at the NATO Summit Wednesday, according to an English translation of her remarks. "Must pay 2% of GDP IMMEDIATELY, not by 2025".
"Trump wants to see our allies share more of the burden and at a very minimum meet their already stated obligations", Sarah Sanders told reporters A source close to French President Emmanuel Macron also played down Trump's words as rhetoric, saying "it is not a new demand".
Trump will meet the Russian leader in Helsinki on 16 July for their first summit amid an ongoing investigation in the USA into possible Trump campaign collusion with Russia.
Mr Trump also spent time with Turkish president Recep Tayyip Erdogan, who has recently been reelected and gained new powers as his country's executive president.
"And frankly maybe everyone is going to have a good relationship with Russian Federation".
Trump's biggest target for criticism, Germany, predicts that it will be spending 1.5 per cent of GDP on its military budget by 2024.
Instead, a series of events - a black-tie dinner with business leaders, a meeting with May and an audience with Queen Elizabeth - will happen outside the bustling city, where Mayor Sadiq Khan has been in a verbal battle with Trump.
The substance is the same military-grade toxin that almost killed a former Russian spy and his daughter in an earlier attack that Britain also blamed on Moscow.
"We will be deploying an additional 440 personnel to NATO's Resolute Support mission in Afghanistan and I think that shows when North Atlantic Treaty Organisation calls, the United Kingdom is one of the first to step up", May told reporters.
Asked about Trump's suggestion, Stoltenberg said he'll focus on what's been agreed to.
