The G-7 summit is shaping up to be the most acrimonious in years, putting pressure on Justin Trudeau as host to bridge a divide between Trump and Europe, with Japan's Shinzo Abe poised to fall somewhere in the middle.
The tweets were in part a response to criticism from French President Emmanuel Macron and Canadian Prime Minister Justin Trudeau on Thursday who said the president's recent moves pulling the USA from the Iran nuclear deal and implementing new trade tariffs have isolated the us on the world stage.
"Now, if we're unable to make a deal, we'll terminate NAFTA", Trump told reporters. "But he doesn't bring up the fact that they charge us up to 300% on dairy - hurting our Farmers, killing our Agriculture", the USA president said.
Beyond the bilateral meetings, the G7 leaders took part in two working groups whrre discussion of trade was front and centre.
She listed the reasons why the G7 yanked Russia's invitation to the club in 2014, including its invasion of Ukraine, the annexation of Crimea and the recent chemical weapon attack on a former Russian spy and his daughter in the British town of Salisbury. The remaining members, led by President Barack Obama, expelled it in a sign of global resolve not to let worldwide borders be redrawn by force. In a statement at the time the countries, which include the U.S., France, Canada, Germany, Italy, the United Kingdom and Japan, condemned Russia's actions as "illegal" and in "contravention of global law". "It is in everyone's interest".
At last year's G7 summit in Sicily, the leaders all signed a communique, but the statement made clear there were deep differences on the Paris climate change accord.

"Whether you like it or not - and it may not me politically correct - but we have a world to run... I think it will be very positive", Mr Trump said, without giving details.
"There are disagreements", Kudlow said.
Trudeau was angered Trump utilized the rarely invoked "national security" provision to justify the tariffs, and in doing so was alluding that Canada was a threat to US national security.
As the two left, a reporter asked if Trudeau was disappointed that Trump was leaving early (Trump will be leaving the G7 early to prepare for his upcoming summit with North Korea's Kim Jong Un) but before Trudeau could respond, Trump jumped in.
While Trump's relationship with some of the G7 members has reportedly been tense, one quickly came to his defense.
While he's taken a tougher stance on traditional USA allies, Trump - who remains under investigation as part of an inquiry into potential collusion between his presidential campaign and the Kremlin - has charted a warmer course with Russian President Vladimir Putin.
"Russia is focused on other formats, apart from the G7", the spokesman stated. Some countries have retaliated with their own levies on USA imports.
"When we can underscore and we see there's a lot of pressure with the U.S., perhaps he will revise his position".
