Meanwhile, Trump continued to talk tough Friday, even threatening to "terminate" the North American Free Trade Agreement, which he has repeatedly characterized as unfair to the U.S.
Trump responded by accusing Macron and Canadian Prime Minister Justin Trudeau of hurting the United States with unfair trade practices. "He is sticking to his guns".
On Thursday, Macron berated Trump for imposing unilateral tariffs on imported steel and aluminium rather than go through worldwide arbitration, and for walking out of a multilateral nuclear deal with Iran. "The lines are open, the negotiations are ongoing". "It will start first of all to hurt USA workers".
Screenshotting a headline about US President Donald Trump's suggestion that Russia be invited back to the group of nations, Conte tweeted: "I agree with President Trump: Russia should return to the G8".
Mr Macron also pushed back against Washington's justification that the United States tariffs are based on national security, saying this was untrue and that the trade dispute would even end up hurting U.S. jobs.
"It may not be politically correct, but we have a world to run".
Canada and the European Union have denounced the USA tariffs and Ottawa has proposed levies on a range of US goods next month while the European Union has pledged its own retaliatory measures.
Mr. Trump's chief economic adviser, Larry Kudlow, played down the feud at a White House briefing Wednesday. It gave Trump a brief respite from criticism over the punishing steel and aluminum tariffs he has imposed on his G7 partners.
"If the numbers are accurate, an additional $70 billion in US exports to China would be considerable - a 50 percent increase in USA exports from 2017 levels", Chad Bown, a senior fellow at the Peterson Institute for International Economics, said in an email.
Just after 6 a.m., Trump used the social media platform to accuse Canada of charging USA customers astronomical tariffs on dairy products.
That's why he sees it as such a great and brilliant victory that he pulled us out of a series of worldwide agreements: the Trans-Pacific Partnership, the Paris Climate Accord, the Iran nuclear agreement. European allies have urged Trump to reconsider.
Italy has always been considered one of the most pro-Russia members of the European Union.
Prime Minister Justin Trudeau is hosting the world's most powerful countries at the two-day summit in La Malbaie, in Quebec's Charlevoix region.
"So, if I can get the president to actually realize that what he's doing is counterproductive for his own goals as well, then perhaps we can move forward in a smarter way".
Sources claimed that the president invoked the War of 1812 when his Canadian counterpart asked him how he could justify the tariff change as a "national security" issue, which the administration had done under a 1962 trade law.
Macron said the message of other G7 leaders to Trump on the Iran deal should be: "You're not comfortable with an agreement signed by your predecessor, maybe just because it was signed by your predecessor, but don't stop others from respecting it and don't push Iran to leave, because today it's the best protection we have". The summit - which includes leaders of the Untied States, United Kingdom, Canada, France, Germany, Italy, Japan, and the European Union - is meant to discuss issues like trade, climate change, and women's rights.
