Speaking to CNN today, Trump adviser Larry Kudlow says he personally negotiated with Trudeau during the two-day G7 summit in Quebec's Charlevoix region and insists the US agreed to the language in the communique in good faith.
"The relationships were outstanding, but because of the fact that USA leaders of the past didn't do a good job on trade-and, again, I'm not blaming countries, I'm blaming our people that represented our past-it's gonna change", Trump said.
The G7 summit participants managed to patch over their disagreements and agree to disagree on some issues in a joint final statement.
In his press conference, Trudeau had spoken of retaliatory measures that Canada would take next month in response to Trump's decision to slap tariffs on steel and aluminium imports from Canada, Mexico and the European Union.
Europe, Canada and Japan are largely united in opposition to Trump's protectionism while trying to find ways to bridge the divide and avoid rupturing the G7, which in its 42-year history has tended to seek consensus on economic and other issues.
Theresa May narrowly survives another Brexit crisis with "backstop plan" on customs
Britain leaves the European Union without any agreement on future relations, and trades on World Trade Organisation terms. The DUP has warned that it will " vote against the Government " should Prime Minister Theresa May agree.
Trump's early departure means he will miss a working session among the leaders on climate change and clean energy, as well as talks among the G7 and poorer countries focused on the health of oceans.
Adding fuel to Trump's bonfire request was newly-installed Italian Prime Minister Giuseppe Conte, who backed the USA president's suggestion.
In a trade war, Trump told reporters that the United States has nothing to lose.
Italy's new Prime Minister Giuseppe Conte also backed Trump's call. Some countries have retaliated with their own levies on U.S. imports. "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, I think it would be good for all of the countries of the current G7", Trump said. Trump will leave the summit early to attend a summit in Singapore with North Korean leader Kim Jong Un on Tuesday.
"I highlighted directly to the president that Canadians did not take it lightly, the United States' move forward with significant tariffs on our steel and aluminum industry", began Trudeau. He says that we are the problem with tariffs.
Trump missed Trudeau's introductory statement at the meeting and entered the room while council co-chair Isabelle Hudon, who is Canada's ambassador to France, was speaking.
