Trump says he ordered his representatives not to sign G7’s final communique

U.S. President Donald Trump's top economic adviser, Larry Kudlow, slammed Canadian Prime Minister Justin Trudeau as having betrayed the United States and making Trump look week ahead of the highstakes summit with North Korea.

Navarro's comments added to the White House's continued criticism of Trudeau, who said after Trump left the G7 summit that Canada would impose retaliatory measures to answer Trump's tariffs and warned that Canada would not be "pushed around".

Tensions between the two allies increased following the Group of Seven summit in Quebec this weekend, when Trump met with leaders of Canada, Britain, Italy, France, Germany and Japan to discuss economic issues facing the nations, including trade relations.

But California Sen. Dianne Feinstein, a Democrat, said Trump wasn't just taking on Trudeau, but all of the United States' best allies by not signing the G-7 statement after a two-day meeting in Canada with leaders of the world's largest industrialized economies.

Also in response, Larry Kudlow, director of the White House's National Economic Council, said on Sunday in an interview with CNN that Trudeau betrayed Trump with "polarizing" statements on USA trade policy.

"Canadians, we're polite, we're reasonable, but we will also not be pushed around".

Trump announced after Trudeau's press conference that the US would not sign onto the G-7 communique.

"I have every desire to see our negotiations with Canada continue productively and beneficially, but Prime Minister Trudeau is sabotaging that cause by driving both sides into their corners instead of encouraging a more diplomatic dialogue", Krishnamoorthi continued.

Officials from European delegations quickly leaked copies of the joint statement, and it was published online moments before Mr Trump tweeted.

Trump was ticked off by Canadian Prime Minister Justin Trudeau taking amateur "pot shots" at him during a press conference after Trump left the G-7 summit en route to Singapore, Kudlow said.

In response, Trump attacked Trudeau on Twitter, calling him "dishonest & weak". "He really kind of stabbed us in the back".

"In a matter of seconds, you can destroy trust with 280 Twitter characters", German Foreign Minister Heiko Maas said when asked about Trump's decision. "That's what weak, dishonest Justin Trudeau did".

"You go tariff-free, you go barrier-free, you go subsidy-free".

Kudlow adds that Trudeau's press conference was indignant and seemed to claim it was an attempt to undermine President Trump's historic summit with Kim Jong un in three days.

"The United States has been taken advantage of for decades and decades, and we can't do that anymore", Trump said.

"I think the pushback by Congress is going to come up incredibly short", Chris Barron, a pro-Trump Republican strategist, said of Republican efforts to rein in Trump.
