President Donald Trump delivered a stern warning on trade to foreign countries at the Group of Seven summit on Saturday, advising trading partners not to retaliate against US tariffs on the imports of steel and aluminum.
Canadian officials said on Friday that talks had been "cordial" throughout the day, and that a constructive discussion had taken place in a private meeting between Trump and Trudeau.
But by insisting on re-negotiating every five years, Trump is diametrically opposed with Canada, which says the sunset clause would create perpetual uncertainty and harm long-term investment.
Going into the summit, Mr Trump was at odds with other leaders on issues such as trade, Iran and climate change.
"Maybe the American president doesn't care about being isolated today, but we don't mind being six, if needs be", Macron 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.
The tensions surrounding the tariffs underscore what appears to be a growing distance between the US and its allies over Trump's isolationist policies, including his decisions to withdraw from the Paris climate accord in 2017 and the Iran nuclear deal in May.
And more: "Looking forward to straightening out unfair Trade Deals with the G-7 countries". It was kicked out of the G8 in 2014 for annexing Crimea from Ukraine.
He said that he did not blame G7 leaders for the "unfair" trade deals, but previous USA presidents.
"I think it would be good for the world, I think it would be good for Russian Federation, I think it would be good for the United States", Trump said.
Vienna has been discussed as a possible venue for a summit between Vladimir Putin and Donald Trump, the Kremlin said Saturday.
Just before taking off from Charlevoix, Que., Trump called the Group of Seven summit "really tremendously successful" before launching into a tirade about how unfairly he believes the countries in the group have been treating the US, while complimenting North Korean leader Kim Jong Un and taking a shot at a reporter from "fake news CNN" in the process.
Despite earlier reports of a rant over trade from Trump, he said the meeting "was not contentious" and called the relationships between the leaders "outstanding".
President Donald Trump has opened his second day at an global summit at a breakfast discussion on gender equality. The U.S. president has recently whacked all the other members of the G7 with hefty steel and aluminum tariffs and is threatening to also impose tariffs on vehicle imports, which would also hit them hard.
"President Trump is targeting the dairy sector because he wants to dump USA dairy into Canada", Lampron told The Canadian Press, adding that Canada imports five times more dairy from the US than it exports.
