The pair have been at odds over whether a sunset clause would be included into any renegotiated trade agreement covering the US, Canada and Mexico, with Mr Trudeau insisting no sunset clause would be included and Mr Trump saying hours earlier that negotiators were "pretty close on the sunset provision".
The Canadian prime minister's office responded to Trump's tweets accusing Trudeau of "false statements" on Saturday, saying that the Prime Minister said nothing during the G7 summit that he had not said previously. I said okay, but so far we're getting nothing.
"We have a great relationship". Angela (Merkel) and Emmanuel (Macron) and Justin (Trudeau) - I would say the relationship is a 10.
Trudeau and Canadian Foreign Minister Chrystia Freeland later tweeted photos of the women's empowerment meeting, showing Trump's empty chair.
Trump and USA allies may need some moisturizer more than Pruitt from the severe tariff chafing they experienced at the G7 summit. Before Trudeau spoke and announced the communique, a USA administration official told a pool reporter Trump had agreed to the communique.
Trump has already initiated a trade war and that trade war is already hurting US businesses and consumers, and will continue to do a so.
"The United States has been taken advantage of for decades and decades", he continued, describing America as a "piggy bank that everyone keeps robbing".
"And that ends", he said, according to a report by New York Times. Before leaving Washington, Mr Trump had said that Russian Federation should be readmitted to the group that had excluded it in 2014 after its invasion of eastern Ukraine and annexation of Crimea.
Battered by Trump, G7 leaders choose to be 'polite,' productive
The Trump administration has imposed aluminum and steel tariffs on the other G-7 members - the United Kingdom, Germany, Italy, France, Canada and Japan - ratcheting up tensions between the us and its allies in the run-up to the summit.
The announcements come as Mr. Trump seeks to make headway on the deep USA trade deficit, saying the country has been taken advantage of for too long, and he is fighting back.
He is now raging on Twitter about a statement given by Canadian Prime Minister Justin Trudeau following Trump's early exit.
He said Saturday that he's also considering scrapping the North American Free Trade Agreement in favor of bilateral trade deals with Canada and Mexico individually. "We have put up with Trade Abuse for many decades - and that is long enough". He kicked off the meeting without waiting for "stragglers" to arrive.
During the summit, Trump was accused of seeking to undermine the "rules-based" global order but the final statement began by stressing "the crucial role of a rules-based worldwide trading system" as well as a commitment to "continue to fight protectionism".
His arrival was impossible to miss as security personnel had to open a path for Trump through a mob of journalists, many of whom were holding large cameras. The camera clicks for Trump nearly drowned out Hudon. In fact, Russian Federation was expelled from what was then the G-8 after it invaded and annexed Crimea and for its support for pro-Russia separatists in Ukraine.
There was also an agreement to disagree on climate change in the wake of Trump's decision to leave the Paris climate accord past year which further underlined the divide between the Group of Seven's powerhouse and its six co-members.
