Trump tweeted that it was that press conference that caused him to instruct US representatives not to sign a joint statement vowing to work on easing trade barriers.
U.S. President Donald Trump throws the G7's efforts to show a united front into disarray after he became angry with Canadian Prime Minister Justin Trudeau, and instructed his representatives NOT to endorse the summit's joint communique.
Trudeau said he told Trump directly that Canada 'particularly did not take lightly the fact that [the tariffs were] based on a national security reason.' The prime minister said in comments reported by CTV: 'Canadians are polite, we're reasonable, but we also will not be pushed around'.
It said that the United States, Canada, Britain, France, Italy, Germany and Japan had agreed on the need for "free, fair, and mutually beneficial trade".
As Trump heads to Canada for this week's meeting of the G7 Group of Nations, the general consensus is that this is more like a G6 plus one- with the United States under Trump the odd country out.
With Trump and Trudeau exchanging increasingly personal and public insults, what happens to those NAFTA negotiations?
Donald Trump said some stupid things about trade at the G7 today in Quebec City. "He's sticking to his guns, and he's going to talk to them".
In response, Trudeau's spokesman said the federal government was focused on what was accomplished at the summit.
Mr Trump's strained relationship with the rest of the G7 was in evidence on Saturday when he arrived late for the opening session, with Mr Trudeau addressing a gathering that included an empty chair where the president was meant to be.
"Applying equivalent tariffs to the ones that the Americans have unjustly applied to us", said Trudeau.
The money raised exceeds the $1.3 billion U.S. over three years that a coalition of 30 non-governmental organizations had called on Prime Minister Justin Trudeau to raise as part of his chairmanship of the G7 this year.
The G7 joint communique, which advocates a "rules-based trading system", was reached despite tension over USA tariffs on steel and aluminium imports, reported BBC.
"Very dishonest & weak", Trump continued.
"Our values and interests are built through multilateralism, including American interests", Macron said in a tweet.
Trump had already roiled G-7 members ahead of the summit and raised fears of a trade war when he placed tariffs on steel and aluminum from Canada, the European Union and Mexico.
He touted the "great meetings and relationships", and said that the other leaders "understand where I am coming from".
The top German diplomat specifically referenced Trump's decision to withdraw from the Iran nuclear deal, the Paris climate accords, and the imposition of tariffs on steel and aluminum as unfathomable measures to take against his nation's closest allies.
The summit was wrapping up just as Chinese President Xi Jinping began hosting the leaders of Russian Federation and Iran at a regional security meeting in a symbol of the power-play between East and West.
