US President Donald Trump said that he is "very, very happy" because NATO members pledged to increase defence spending to levels "never seen before", despite denials from allies, such as France, that any additional pledges were made beyond previous targets.

In a news conference after a NATO summit in Brussels on Thursday, Trump said NATO members would increase their contribution at a "much faster clip" than previously scheduled.

"We made a tremendous amount of progress today," Trump said. "The United States' commitment to NATO remains very strong," he said, adding that it was "much more powerful than two days ago".

French President Emmanuel Macron, however, denied Trump's claim that NATO powers agreed to increase their defence spending beyond what they had already committed, according to the Associated Press news agency.
