As Trump flew from the summit with USA allies to a planned meeting with North Korean leader Kim Jong Un in Singapore, he lashed out at Trudeau for what he said were his "false statements" at a news conference and said the US would not endorse the G7 communique, a negotiated statement on shared priorities among the group.
Mr. Trump's tweets taking aim at the leader of a country that has always been a USA ally came after the President left the G7 summit in Canada to travel to Singapore ahead of a planned diplomatic meeting with North Korean Leader Kim Jong-un, CNN reported.
Just as the Trudeau-hosted Group of Seven meeting of the world's leading industrialized nations had seemed to weather Trump's threats of a trade war, the president backed out of the group's joint statement that Trudeau said all the leaders had come together to sign.
Sharply criticizing Trump's remarks on tariffs, Prime Minister Trudeau promised that Canada would answer with its own on July 1 unless the USA reversed course. Trudeau said he is "not remotely interested" in having Russian Federation rejoin the group.
Merkel said she will keep talking with Trump., but renewed her call for Europe to take a more forceful role in global affairs and said the European Union won't be "take for a ride" in its trade conflict with the US.
President Trump withdrew from a joint statement with G7 allies on trade because he needed to show toughness before his historic negotiations with Kim Jong Un, according to his chief economic adviser.
That was part of a string of messages in which the president asserted the United States "pays close the the entire cost of NATO" while other member countries take advantage of the US on trade.
Trudeau had announced that the G7 members - Canada, France, Germany, Italy, Japan, the United Kingdom and the USA - had agreed upon a joint communiqué, or formal statement, after a hard week on trade issues.
The move enraged Trump, who branded his Canadian counterpart "dishonest and weak" in a furious tweet, announcing the United States would pull out of an agreed communique.
But Kudlow probably didn't help the message he was sending to the Canadian leader by once referring to him as "Pierre Trudeau".
"We're like the piggybank that everybody is robbing", Trump said while addressing a press conference on Saturday. "He did a great disservice to the whole G-7".
Why did Trump act against the G-7?
"We are not going to live with the deals the way they are", he said.
"I don't blame other leaders for that", Trump said. "I don't understand the obsession with trade relations with Canada", he said on Fox's "Sunday Morning Futures", given that Canada is the biggest single buyer of American goods and services in the world.
Trump left the summit early, after about 24 hours in Canada, to go to Singapore where he is set to meet the leader of North Korea on Tuesday. "As Canadians, we're polite, we're reasonable, but also we will not be pushed around", he said.
But Kudlow said he doesn't know whether there will be a deal and that Trump had no alternative but to respond the way he did to Trudeau's "very unfortunate" statements.
