"I think that getting along with Russian Federation, getting along with China, getting along with others is a good thing, not a bad thing", Trump said.
"They got rid of their coal plants, they got rid of the nuclear".
"They made tremendous success and I believe our trade will increase and lots of other things but we will see what happens over the next few months".
"Because of me they've raised about $40 billion over the previous year".
In a startling public outburst against one of Europe's main military powers, Trump told NATO Secretary General Jens Stoltenberg that Germany was wrong to support a new $11 billion Baltic Sea pipeline to import Russian gas while being slow to meet targets for NATO spending to protect against Russia.
Stoltenberg acknowledged that Trump had expressed himself in "very direct language" but insisted that away from the fiery rhetoric the allies all agree on fundamental issues: the need to boost NATO's resilience, fight terror and share the cost of defence more equally. So I think the secretary-general likes Trump.
The US president has made clear that he will continue on his drive on defence spending, and is now calling for North Atlantic Treaty Organisation countries to increase their commitment for defence spending to 4 per cent of gross domestic product, double the previous target. "And I think we have to talk to Germany about it".
'The U.S.is paying for Europe's protection, then loses billions on Trade.
The Brussels meeting comes less than a week before Mr Trump is due to hold his first summit with Vladimir Putin, in Helsinki, reviving concerns among U.S. allies over his proximity to the Russian president.
He also said that his meeting with Russian President Vladimir Putin in Helsinki next week would be the "easiest" of the meetings he'll have while he's overseas.
"It certainly doesn't seem to make sense that they pay billions of dollars to Russia, and now we have to defend them against Russia", Trump said.
Despite Trump's claims about Germany, Merkel served as a forceful advocate for imposing - and maintaining - sanctions on Russian Federation after it annexed Crimea in 2014, arguing that it violated the principles of the global order established after World War II.
"We have a very, very good relationship with the chancellor".
Lieu went one step further, drafting an illustrated message to mock the president for his hostile comments to US allies.
"It's very important that we have these exchanges together because we are partners, we are good partners and we wish to continue to cooperate in the future", she told reporters.
Throughout the day, leaders were peppered with questions about Trump's behavior and whether or not they agreed with his position on Germany.
Trump has long complained that European NATO members do not pay enough for their own defence, singling out Germany for particular criticism.
