Trump - who left the G-7 summit and headed to Singapore for his planned summit with North Korean leader Kim Jong Un - lashed out at Trudeau after revoking US endorsement of the communique, dubbing the Canadian prime minister "meek and mild".
At what a French described as one "extraordinary" session on Friday, leaders who had vowed to confront Trump over his decision to impose tariffs on US allies last week as part of his "America First" agenda, showered Trump with data one after the other. To United States, frankly, it would be a good thing but I'm not looking to do that.

Trump said that would be a bad idea.
"We stick to the communique as agreed by all participants", a European official said on condition of anonymity.
Trump added that the meeting was a "one-time shot" but he thought it would "work out very well".
He rebuked Canadian Prime Minister Justin Trudeau for being "dishonest & weak" and making "false statements".
He said the USA required fair access to markets and an end to unfair trade practices, telling reporters the "United States has been taken advantage of for decades and decades". The United States pays enormous tariffs on dairy.
European officials said Trump had opposed language in the draft final summit communique on the need to bolster the World Trade Organization and multilateral oversight of commerce, but that this commitment would survive.
"The nature of the debate we had was rather appeasement and it stopped the escalation in terms of behavior", Macron, who had exchanged terse Twitter messages with Trump in the run-up to the summit, told reporters.
"At the same time we will not stop trying to convince our American friends and President Trump that undermining this order makes no sense at all, because it would only play into the hands of those who seek a new post-West order where liberal democracy and fundamental freedoms would cease to exist".
The bombshell tweet came after G7 nations appeared to have papered over the cracks in their alliance at the two-day summit in La Malbaie, Quebec, where Trump defiantly brandished his "America First" agenda.
Still, the United States and European Union will establish a dialog on trade within the next two weeks, signaling a modest step forward for the bitterly divided allies of the G7.
The US leader left the summit earlier than planned on Saturday to fly to Singapore to meet with North Korean leader Kim Jong-un, which he described as a "mission of peace". "So we are going in with a really positive spirit".
On Saturday, Mr. Trump arrived late for the first working session on gender equality but Canadian Prime Minister Justin Trudeau forged ahead with opening remarks without him, commenting wryly about "stragglers".
"President Trump is targeting the dairy sector because he wants to dump US dairy into Canada", Lampron told The Canadian Press, adding that Canada imports five times more dairy from the USA than it exports.
