Meanwhile, Trump's off to Singapore to meet up with North Korea's Supreme Leader Kim Jong-un who landed in the country earlier today. Later, the document was made public.
Trump then called Trudeau "Very dishonest & weak" in a follow-up tweet.
The money raised exceeds the $1.3 billion USA 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 attack shattered any hope that Canada could avoid US tariffs on steel and aluminum or renegotiate the North American Free Trade Agreement by virtue of the charm, patience or measured response it has extended to Trump since he took office. "He really kind of stabbed us in the back. I have made it clear to the president that [imposing retaliatory tariffs] is not something we relish doing, but it's something that we absolutely will do", Trudeau said. "We can't lose it", he said.
Trump said Saturday evening that he had instructed US officials to withdraw support for a joint statement with other member nations he had backed just hours earlier, saying the United States would not join after Trudeau publicly criticized Trump's trade policy.
The communique, which appeared to have papered over the cracks that have surfaced in the G7, said the leaders of the United States, Canada, Britain, France, Italy, Germany and Japan agreed on the need for "free, fair, and mutually beneficial trade" and the importance of fighting protectionism.
Up until now, the German government has largely adopted a policy of quiet disapproval in Trump's direction, but Maas broke the silence ahead of the G7 summit in Canada, which begins Friday.
Trump did not specify which of Trudeau's statements he considered false.
According to a report by the Independent, the joint communique stated that the G7 nations need to evaluate global trade rules and develop new ones, if necessary, going forward to ensure an equal trading playing field. "I think within the first minute I'll know", Trump said. "And we charge nothing", Trump said. "What was strong was the language that this can not go on, but the relationships are very good". Bannon said China is "now on notice that Trump will not back down from even allies" complaints in his goal of "America First"'. But the summit host, Trudeau, whose nation was among those singled out by Trump, pushed back and said he would not hesitate to retaliate against his neighbor to the south.
Trump repeated his criticism of Canada's supply managed dairy industry, one of his favourite targets in Twitter posts, including this week prior to his arrival in Canada.
British Prime Minister Theresa May said the other G7 leaders registered their "deep disappointment at the unjustified decision by the U.S." on its closest allies. That means the Nafta process - negotiating a deal, and then passing it in each country - is nearly certain to run into 2019. "And that ends", Trump said.
