Trump has long called on Canada to stop protecting its dairy farmers from USA competition amid ongoing efforts to renegotiate the North American Free Trade Agreement (NAFTA).
The two leaders offered that olive branch to Trump on Thursday ahead of his arrival at the G7 summit in Quebec on Friday, where disagreements on trade will be front and centre.
Mr Trump, who has vowed to protect USA industry and workers from what he describes as unfair worldwide competition as part of an "America First" agenda, is due to hold bilateral meetings with Mr Trudeau and French President Emmanuel Macron during the summit, Mr Kudlow said. "And we don't want there to be one", Macron said.
G7 leaders will pressure US President Donald Trump at a summit this week on tariffs he has imposed on metals imports but must remain civil as they try to persuade him to change his mind, French President Emmanuel Macron said today.
"Mr. Trump is a businessman who knows where he's going and knows what he's doing", Belanger said.
Trudeau said Thursday he pointed out this piece of history to Trump in a recent discussion. Ask some people in Canada and they would very much feel it was their war, marked by American aggression. All members would also pledge to respect rules, and seek a reform of the World Trade Organization.More news: Golden Knights to host Game 4 watch party inside T-Mobile Arena
According to CNN's sources familiar with the conversation, Trudeau pressed Trump on his national security justification for the tariffs, to which Trump replied: "Didn't you guys burn down the White House?".
British Prime Minister Theresa May took a more measured tone, telling reporters she wanted the European Union to use restraint in its retaliation to the US tariffs and that the response must be proportionate and legal.
Just days before Trudeau is set to host a G7 Summit in Quebec, Canadian officials tell CNN they are just trying to "keep Trump happy".
In response to slow moving NAFTA talks, the US announced it was ending an exemption on steel and aluminum tariffs that initially had been granted to Canada, Mexico and the EU.
The reports do not say what types of penalties are being looked at. Pleas by the other member countries for exemptions from the United States steel and aluminum tariffs, which went into effect on June 1, have fallen on deaf ears in Washington.
Mr. Trump is exploiting a "national security" loophole in global trade law to justify his tariffs, and worldwide tribunals may have little choice but to defer to his sovereign determination in this regard, even if it's not in good faith. European allies have urged Trump to reconsider.
President Emmanuel Macron has signaled that progress on tariffs, Iran nuclear agreement and Paris climate accord must be made before he'll be willing to sign a joint statement, the official told reporters Wednesday in Ottawa. France would also oppose any wording that described the Iran pact as obsolete, the official added.
The comments by the two leaders at a Parliament Hill news conference before they each departed to Charlevoix for the summit laid bare the frustrations and even anger at Trump's policy decisions.
