Mr Trump had already threatened to divide the G7, made up of the US, France, UK, Italy, Germany, Japan and Canada, when he suggested Russian Federation should be allowed to rejoin the group.
Trump administration members continued a war of words with a traditional USA ally Sunday, accusing Canadian Prime Minister Justin Trudeau of stabbing the president's team in the back. European allies on Monday backed Trudeau in the spat with Trump and stressed that they will retaliate against the US tariffs with duties on USA goods. The New York Times reported that Trump has defiantly refused to sign the trade agreement or verdict signed by all nations present at the summit. "I highlighted directly to the president that Canadians did not take it lightly that the United States has moved forward with significant tariffs on our steel and aluminum industry", Trudeau said Saturday. "Our tariffs are in response to his 270 percent on dairy".
Asked about Trump's threat to target United States tariffs against cars - a vital industry for Germany which supports over 800,000 jobs - "we will have to think again about what we'll do", Merkel said.
"Walk into a summit meeting with the largest economies in the world, all U.S. Allies". "And that's what bad faith Justin Trudeau did with that stunt press conference". "Let us be serious and worthy of our people", the statement said. Trump advisers described Trudeau's statements as a slight that threatened to make the USA look weak right as the president was leaving for a summit with North Korean dictator Kim Jong Un.
"Well, he holds a press conference and he says the U.S.is insulting".
"International cooperation can not be dictated by fits of anger and throwaway remarks", President Emmanuel Macron's office said in a statement to AFP, adding that reneging on the commitments agreed in the statement showed "incoherence and inconsistency".
The amount was more than feminists groups that met with Trudeau on the sidelines of the summit had asked for, earning the G7 praise from civil society groups and activists, including Nobel prize-winner Malala Yousafzai who said it would "give more girls hope that they can build a brighter future for themselves".
Canada's foreign minister, Chrystia Freeland, said her country "does not conduct its diplomacy through ad hominem attacks".
In a news conference after the summit, Mr Trudeau had said that while he did not want to "punish American workers", his job was to protect Canadians and as such he would press ahead with tariffs on some United States imports.
"To answer this tweet and Trump's provocation at the G7 - if Russian Federation does not demonstrate any move forward, and we will invite them back, no one would understand this".
Mrs Merkel announced that the European Union would form counter-measures to Trump's steel and aluminium tariffs, which are expected to be announced on July 1.
Trade adviser Peter Navarro told "Fox News Sunday" that "there is a special place in hell for any leader that engages in bad faith diplomacy" with Trump. "They should let Russian Federation come back in because we should have Russian Federation at the negotiating table". "I have instructed our U.S. Reps not to endorse the Communique as we look at Tariffs on automobiles flooding the U.S. Market!" he wrote. He really kind of stabbed us in the back.
