Canadian Foreign Minister Chrystia Freeland had responded to the White House comments by saying that Canada will retaliate to U.S. tariffs in a measured and reciprocal way and that Canada will always be willing to talk.
While Trump also presented the idea that the member countries should drop off tariffs and trade barriers, he also reportedly complained to the other leaders about their trade policies and said the U.S. would continue with tariffs absent concessions.
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 us trade policy.
White House aide Larry Kudlow tells CNN's "State of the Union" says Trudeau has done a "great disservice" to the G-7 by saying Canada had to stand up for itself and that the USA was responsible for the problem with tariffs.
In response to Mr Trump's decision to withhold U.S. support for the summit conclusions, a senior United Kingdom government source said: "We stand by the commitments made in the G7 communique". "But we say that with great sadness".
Norwegian Prime Minister Erna Solberg said the United States loses influence in the world after Trump pulled back support of the G7 summit statement, public broadcaster NRK reported Sunday. "We joined the communique in good faith", Kudlow said. "He did a whole disservice to the whole G-7".
US President Donald Trump called Mr Trudeau "very dishonest and weak" after leaving the Group of Seven heads of government meeting in Canada on Sunday, shattering any hope its northern neighbour could avoid US tariffs on steel and aluminium, or renegotiate the North American Free Trade Agreement.More news: Come watch Square Enix's E3 2018 showcase with us!

Peter Navarro, Trump's most protectionist trade adviser, said there was "a special place in hell" for Trudeau after what he called the prime minster's "stunt press conference". Trudeau did not make President Trump look weak. "And that comes right from Air Force One".
Later on June 9, after he left the G7 summit, Trump unleashed a barrage of tweets, likely while he was aboard Air Force One on his way to Singapore for his summit with North Korean leader Kim Jong Un - "Just left the @G7 Summit in lovely Canada".
Trump, who is in Singapore for negotiations with North Korea, continued to rip into USA trading partners late Sunday night Eastern Time, repeating complaints about the United States trade deficit and contributions to NATO.
"Kim must not see American weakness", Kudlow said. Kudlow was referring to North Korean leader Kim Jong Un. "He can't do that".
Unbowed, Mr Trump tweeted anew on Monday morning from Singapore: "Fair Trade is now to be called Fool Trade if it is not Reciprocal". The EU trade surplus with the U.S.is $151 Billion, and Canada keeps our farmers and others out. "Minimum is 17B. Tax Dairy from us at 270%", he wrote in the first of five tweets relating to the weekend's summit. Senator John McCain responded to these tweets by supposedly speaking for the American people and saying that the country stands with the rest of the G7 countries, even if President Trump does not. "$800 Billion Trade Deficit ..."
"The whole tone of the bilateral rhetoric between Canada and the US seems to have deteriorated quite significantly", he said. "Canadians, we're polite, we're reasonable, but we also will not be pushed around", he said.
He also says Canadians expect him to foster with Trump "a constructive, productive relationship in which we can work together, that is based on not insulting and disrespecting each other".
