"This isn't just G7. Well, the in-factual, the non-factual part of this was they have enormous tariffs", Kudlow said. A hundred per cent. And so we are talking to many countries. And it's going to stop.
Navarro was referring to the prime minister's announcing after the Group of Seven meeting Saturday that Canada will "not be pushed around" by the US with its decision to slap tariffs on some imports from Canada and other countries.
In a tweet posted Saturday evening, Trump said his decision to rescind support for the statement was based on "false statements" made by Trudeau during a press conference he gave, as well as "the fact that Canada is charging massive Tariffs" on us companies. At one point he wrote, "Justin acts hurt when called out!"
The prime minister also said Canada would "move forward with retaliatory measures on July 1, applying equivalent tariffs to the ones that Americans have unjustly applied to us".
The president also repeated claims that Canada overtaxes American dairy products under its supply management system and complained about Canadian automobiles entering the US market.
The President ripped Trudeau on twitter over his "false statements" to the press; adding that he instructed his administration "not to endorse" a joint statement from the G7 countries following the contentious summit.
In a separate interview on CBS's "Face the Nation", Kudlow said the Trump had a "very successful, calm, friendly, respectful bilateral" with Trudeau and that the U.S. won't withdraw from Nafta.
His aides took the matter further.
Larry Kudlow, director of the National Economic Council, lashed out at Canadian Prime Minster Justin Trudeau as "amateurish" and "sophomoric" for a news conference he gave after Trump left the Group of Seven summit on Saturday. He really actually, you know what?
"We went through it".
Despite the differences, the leaders did manage to agree a joint communique at the summit.
Conservative Leader Andrew Scheer said on Twitter on Sunday that the G7 meeting "shows that united support for free trade is at serious risk".
Asked what Trudeau did that amounted to betrayal, Kudlow criticized the Canadian leader for holding a press conference in which he called US tariffs "insulting".
- Donald J. Trump (@realDonaldTrump) June 11, 2018Why should I, as President of the United States, allow countries to continue to make Massive Trade Surpluses, as they have for decades, while our Farmers, Workers & Taxpayers have such a big and unfair price to pay?
"He held a press conference and he said the U.S.is insulting. That's what weak, dishonest Justin Trudeau did, and that comes right from Air Force One", he continued.
In Quebec City early on Sunday, Trudeau declined to answer reporters' questions about the aftermath of the two-day G7 summit in Quebec.
The G7 also includes Britain, Italy, France, Germany and Japan. "The Prime Minister said nothing he hasn't said before - both in public, and in private conversations with the President", the office added.
"I think the G8 would be better, I think having Russian Federation back in would be a positive thing". "I'm arguing Trudeau picked the fight", he said.
