Slamming European allies and Canada, Trump said 'Fair Trade is now to be called Fool Trade if it is not Reciprocal;.

Trump, who is currently in Singapore to meet North Korean leader Kim Jong Un, tweeted: "Fair Trade is now to be called Fool Trade if it is not Reciprocal. According to a Canada release, they make almost 100 Billion Dollars in Trade with U.S. (guess they were bragging and got caught!). Minimum is 17B. Tax Dairy from us at 270%. Then Justin acts hurt when called out!."

"Why 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? Not fair to the PEOPLE of America! $800 Billion Trade Deficit..And add to that the fact that the U.S. pays close to the entire cost of NATO-protecting many of these same countries that rip us off on Trade (they pay only a fraction of the cost-and laugh!). The European Union had a $151 Billion Surplus-should pay much more for Military!," he said.

He said: "Germany pays 1% (slowly) of GDP towards NATO, while we pay 4% of a MUCH larger GDP. Does anybody believe that makes sense? We protect Europe (which is good) at great financial loss, and then get unfairly clobbered on Trade. Change is coming!."

Trump said his government will give its first priority to American workers.

"Sorry, we cannot let our friends, or enemies, take advantage of us on Trade anymore. We must put the American worker first!," he said.

Trump slams Trudeau:

Trump, who was attending the G7 Summit last week, attacked Canadian PM Justin Trudeau after he refused to endorse the G-7 declaration calling for a reduction in various barriers to trade, including tariffs.

Attending the G7 Summit, US President Donald Trump accused Canadian PM Justin Trudeau of making 'false statement' and said his nation will not endorse the G7 communique. 

"Based on Justin’s false statements at his news conference, and the fact that Canada is charging massive Tariffs to our U.S. farmers, workers and companies, I have instructed our U.S. Reps not to endorse the Communique as we look at Tariffs on automobiles flooding the U.S. Market!," Trump tweeted.

Trump said Trudeau acted 'meek and mild' during the G7 meetings.

"PM Justin Trudeau of Canada acted so meek and mild during our @G7 meetings only to give a news conference after I left saying that, “US Tariffs were kind of insulting” and he “will not be pushed around.” Very dishonest & weak. Our Tariffs are in response to his of 270% on dairy!," he said. 

Larry Kudlow  attacks Trudeau:

President Donald Trump's chief economic adviser Larry Kudlow also criticised Trudeau and said he has performed an 'act of betrayal.

"It was a betrayal," Kudlow said on CNN's "State of the Union." "He really kind of stabbed us in the back," Kudlow said.
