President Donald Trump on Wednesday blasted Canadian Prime Minister Justin Trudeau as “two-faced” after a video showed some important foreign leaders joking and laughing about Trump during a private exchange at the NATO summit in London.

“Well, he’s two-faced,” the US President said, adding that while Trudeau is “a nice guy,” he was likely upset by his demands for Canada to increase its defense spending contribution as part of the Western military alliance.

“I called him out on that, and I’m sure he wasn’t happy about it, but that’s the way it is,” Trump said. “Look, I’m representing the U.S., and he should be paying more than he’s paying, and he understands that. So I can imagine he’s not that happy, but that’s the way it is.”

In the video from the reception,  Trudeau is seen laughing about Trump’s lengthy Q&A sessions with reporters and saying even the president’s staff were shocked at some of his actions.

The video further shows PM Boris Johnson ask: “Is that why you were late?”, as he stoops down and chuckles in disbelief, before Canadian leader Trudeau, swigging from his drink, shoots back: “He was late because he takes a 40 minute press conference off the top.”

The video then cuts to a later clip, which is without context, and sees Macron pointing furiously before Mr Rutte exclaims “Fake news media” and Trudeau adds: “You just watched his team’s jaws drop to the floor.” He then motions as if his jaw is dropping.

At the press conference yesterday, Trudeau explained that his remark about Trump’s team’s jaws dropping was with regard to his announcement that next June’s G7 meeting, which will be hosted by the United States, will be held at Camp David.

“We were all surprised and I think pleased to learn that the next G7 will be at Camp David. I think that was an unscheduled announcement and I think everyone’s team, everyone different leader has teams that every now and then have their jaw drop at unscheduled surprises like that video itself for example,” Trudeau said.

‘As we talk to G7 leaders there is an interest in where the next G7 meeting is going to be and I was pleased to share with them the story of how that came about, that we are going to be gathering, apparently, at Camp David,’ Trudeau said.
