While at the Summit in Quebec, Canada, Trump blasted the foreign leaders who were there with him as they jointly were supposed to come up with new solutions and possibilities for trade.
The statement added "France and Europe maintain their support" for the G7 conclusions.
On 31 May, the Trump administration confirmed that it would be going ahead with imposing additional tariffs on steel and aluminium imports from Canada, Mexico and the European Union, with trump tweeting about rectifying "unfair Trade Deals with the G-7 countries" hours before the summit. "He really kind of stabbed us in the back".
Speaking to CNN today, Trump adviser Larry Kudlow says he personally negotiated with Trudeau during the two-day G7 summit in Quebec's Charlevoix region and insists the United States agreed to the language in the communique in good faith.
The US President's announcement, made after he left the summit in Canada early, torpedoed what appeared to be a fragile consensus on the trade dispute between Washington and its allies. So, I ask you: "He gets up in the airplane and leaves, and then Trudeau starts blasting him at a domestic news conference?" he asked CNN's Jake Tapper.
The photograph proved popular on social media, with many commenting on how symbolic the photo is, given Trump's relations with some of the leaders in the room following his new tariffs.
He followed up by tweeting: "PM Justin Trudeau of Canada acted so meek and mild during our @G7 meetings only to give a news conference after I left saying that, "US Tariffs were kind of insulting" and he "will not be pushed around".
Mr Trump denied that the summit had been contentious, a remark that contradicted what one G7 official described as a bitter harangue on Friday between the US President and his counterparts over tariffs.
The communique was confirmed by Prime Minister Trudeau, who said that Trump's tough talk on trade shows that there is a lot of work to be done between the countries.
The joint statement between the leaders of G7 nations comes after President Trump refused to back down from his decision to impose worldwide tariffs on goods, including steel and aluminum imports.
"President Trump played that process in good faith", Kudlow said.
The two-day summit in Canada has been marred by a tit-for-tat exchanges of hostile tweets, with USA trading partners furious over Trump's decision to impose tariffs on steel and aluminum imports from Canada, the European Union and Mexico as part of his "America First" agenda.
"Canadians are polite and reasonable, but we will also not be pushed around", the prime minister said. "And we don't want there to be one", Macron said. Earlier this week, Merkel said the group is defined by its members' respect of global law, and Russia's 2014 annexation of Crimea was a "flagrant breach" of that.
In response, Canada, Mexico and the European Union said they were putting in place their own retaliatory measures.
The communique signed by the leaders agreed on the need for "free, fair and mutually beneficial trade" and the importance of fighting protectionism.
