But even this was overshadowed by Canadian host Prime Minister Justin Trudeau vowing to impose retaliatory tariffs on U.S. goods after Trump's "insulting" decision to invoke national security to justify a levy on aluminum and steel.
Trump has periodically expressed skepticism about the USA intelligence community's conclusion that the Kremlin meddled in the 2016 election that he won, and he has forcefully rejected assertions that Russian Federation was responsible for his victory. "It's going to stop".
"We have a very really good relationship, very special" - Trump insists he's still best buddies with Emmanuel Macron after his latest no-holds barred handshake with the Frenchman. "We're like the piggy bank that everybody is robbing and that ends".
In a lengthy press conference ahead of his departure on Saturday, Trump said he spoke to world leaders about trade policies and called for the elimination of tariffs, trade barriers or subsidies. Trump has made "America First" an unofficial slogan for his administration. The noise of Mr Trump's helicopter landing was so loud they had to stop talking for a while, in a scene one official compared to the opening from the United States television series M.A.S.H. He doubled down on the criticism during private meetings with his counterparts, according to The New York Times, which wrote that he was met by substantial pushback.
Speaking at a news conference, he described as "insulting" Mr Trump's decision to invoke national security concerns to justify steel and aluminium tariffs.
"It was not contentious", he said, according to The Washington Post. The language, however, was strong, he added.

Airstrips have already been constructed, and in May, China landed nuclear capable bombers on contested islands in the area. He is also the head of the Chinese delegation to the dialogue, which opened in Singapore on Friday and runs through Sunday.
The picture, taken on Saturday by German government photographer Jesco Denzel, shows a standing Mrs Merkel with her hands firmly planted on a table staring down at Mr Trump, who is seated with his arms folded and eyes glaring. "Look forward to seeing them tomorrow".
President Donald Trump delivered a stern warning on trade to foreign countries at the Group of Seven summit on Saturday, advising trading partners not to retaliate against US tariffs on the imports of steel and aluminum.
He also defended the wisdom of his controversial tariffs, saying that the USA would win a trade war against its allies because "they do so much more business with us than we do with them".
That worldwide order appears to be in disarray now, nearly everyone agrees, including the U.S. leader largely responsible for the upheaval.
While Trump set a combative tone before even arriving at the summit with tweets about unfair trade deals, he appeared affable and joking at multiple brief photo opportunities and praised Macron for helping to work out trade issues.
