"I think we go into that meeting not looking for so much", Trump said.
The emergency session came amid reports that Trump had threatened to leave the alliance if allies didn't immediately up their spending, but officials said no explicit threat was made. Trump also prepared to make a previously unscheduled public statement, the White House said.
"We've had a very incredible two-day period in Brussels", Trump told reporters. It's very detailed", he said adding, "It confirms the goal of 2 percent by 2024.
"There is a communique that was published yesterday".
And on Iran, Trump said he believes the government there is "feeling a lot of pain right now" due to tight sanctions.
According to CNN, he said: "I told people that I would be very unhappy if they didn't up their commitments very substantially".
Asked about Trump's suggestion, Stoltenberg said he'll focus on what's been agreed to. Going into the week he was pressuring them to spend 2 percent of their gross domestic product (GDP) on defense, a figure that was established in 2002 and reaffirmed in 2014 when the allies not meeting the target pledged to reach it within a decade.
As he flew off to the United Kingdom on Thursday for the next leg of his European tour, it was left to President Emmanuel Macron of France to correct the record following Trump's freewheeling press conference in which he claimed to have pushed allies into new defence spending commitments.
At present, North Atlantic Treaty Organisation has 29 members and few have reached this goal - only five North Atlantic Treaty Organisation members are expected to meet the 2% target by the end of the year.
Unai Emery says Jack Wilshere Arsenal decision was 'tactical and technical'
We will only sign a player in the next month if he's a big opportunity. I explained to him my opinion and how I will want to create the team.
Separately, Trump also dealt with the ongoing discussions with the European Union on the steel and aluminium tariffs, noting that "Both of my parents are from the European Union, despite the fact they don't treat us well on trade".
Sen. John McCain issued a stern warning Thursday to President Trump in advance of his summit with Vladimir Putin, saying that it would be "a serious indictment" of Trump's leadership if he does not hold the Russian leader accountable on a range of actions.
Trump insisted that he would bring up key subjects including Syria, although he once again failed to rule out recognising Russia's annexation of Crimea.
Trump said he told "people" that he would be "very unhappy" if they didn't increase their commitments. The US is paying for Europe's protection, then loses billions on Trade. He said the 29-nation alliance supports the territorial integrity of Georgia, including its sovereignty over the breakaway regions of Abkhazia and South Ossetia. Trump tweeted on Thursday morning before the second day of talks.
Mr Trump said he didn't want Russian Federation to be a threat, while adding that his meeting with Mr Putin next week "may be the easiest on his Europe trip".
As well as Merkel, Spanish Prime Minister Pedro Sanchez and Charles Michel, the prime minister of Belgium, were also singled out by Trump for undershooting on their spending targets while US taxpayers - funding a defense budget worth about 3.6 percent of their national income - foot much of NATO's bills.
"I don't. I'm very consistent".
"Throughout my life, my two greatest assets have been mental stability and being, like, really smart", the president tweeted. It is not to be excluded that Trump said something similar over dinner, in a smaller circle. So, in a stroke, he shifted attention away from his own ties to the Kremlin just days before he meets one-on-one with Putin. "Nato is very important but it's helping Europe far more than it's helping us".
