Leaders of the Group of Seven rich nations are set to clash with a combative US President Donald Trump when they pressure him to lift sanctions on steel and aluminium they fear could lead to a trade war.
The confrontation threatens to rupture a body that during its 43-year history has traditionally sought to find consensus on the economy and other issues.
Trump, who aides say has little interest in multilateralism, resumed his tirade against Canada early on Friday and appeared prepared to exit talks early without a consensus agreement among all seven countries.
"Looking forward to straightening out unfair Trade Deals with the G-7 countries. If it doesn't happen, we come out even better!" Trump tweeted ahead of his planned departure from Washington to Quebec.
Officials concede the mood is likely to be exceptionally tense.
"There will be some serious disagreements on a lot of things," a Canadian official told reporters late on Thursday.
Although Trump says the tariffs are necessary to protect US industry, Canada and the European Union have denounced them as illegal and are preparing retaliatory measures.
French President Emmanuel Macron warned Trump in a rare rebuke on Thursday that the other six members of the G7 could form their own grouping if necessary, adding that "no leader was forever."
British Prime Minister Theresa May took a more measured tone, telling reporters she wanted the European Union to use restraint in its retaliation to the US tariffs and that the response must be proportionate and legal.
Trump showed no sign of backing down on Friday, after earlier accusing both France and Canada of imposing massive tariffs on US goods and then accusing Canadian Prime Minister Justin Trudeau of "being so indignant."
In response, the Canadian official replied that "the prime minister and the president have very frank, direct, candid, honest conversations."
The White House subsequently announced the president would be leaving on Saturday, before the summit formally ends, to fly to Singapore for a meeting with North Korean leader Kim Jong-un.
While the G7 leaders have largely praised Trump for his efforts to stabilise the Korean peninsula, they are unhappy he pulled out of an agreement designed to limit Iran's nuclear ambitions.
The arguments threaten to derail a meeting that Trudeau had planned to focus on inclusive growth, gender equality and protecting oceans.
In Germany, top officials called for Europe to remain unified in the face of rising trade tensions with the US even as they maintained that America remained its closest partner outside of the continent.
