Canadian dairy farmers say hands off their protections as Trump demands concessions

But Trump didn't seem impressed by the comment.

"I see the television and he's giving a news conference about how he "will not be pushed around" by the United States".

"To leave Canada the way that we did and to make the statements about a trusted ally like this is just wrong", Flake told reporters, according to ABC News.

However, following the summit, Trump tweeted that he was going not going to support the communique, leaving numerous United States' closest allies aghast.

Republican Senator Susan Collins of ME said that while her state has experienced "frictions" with Canada over lobsters and other goods, the USA should not be alienating one of its biggest trading partners.

Hours after Trump withdrew his support for the joint statement and attacked Trudeau, White House economic adviser Larry Kudlow and trade adviser Peter Navarro drove the message home on Sunday morning news shows in an extraordinary assault on a close USA ally and neighbor.

"It's very unfair to our farmers, and it's very unfair to the people of our country", Trump said Tuesday in Singapore.

Trudeau said after the G-7 meeting that the aluminum and steel tariffs imposed by the USA on Canada on national security grounds were insulting and that "Canadians are polite, we're reasonable, but we also will not be pushed around".

President Donald Trump's chief economic adviser Larry Kudlow and his trade adviser Peter Navarro blasted Canadian Prime Minister Justin Trudeau on Sunday for "betraying" the United States and engaging in "bad faith diplomacy" at this week's fractious G7 summit.

Canada is on of the US's largest trade partners, with $673.9 billion worth of goods and services going between the two countries in 2017. Perhaps they were trying to show the power they have.

The U.S. actually has a trade surplus with Canada. "They don't take our farm products", Trump complained at the news conference Tuesday.

Canadian Foreign Minister Chrystia Freeland responded to the White House assault by saying ad hominem attacks are not helpful, that Canada will retaliate to US tariffs in a measured and reciprocal way and that Canada will always be willing to talk.

In recent trade deals with the European Union and a group of Asia-Pacific nations, Canada conceded larger tariff-free dairy quotas.

Mr. Trump's actions led to an extraordinary juxtaposition: an abrupt public feud and deterioration of ties between the USA and Canada at the same moment as warm words and a detente between the US and North Korea.
