Just when it seemed like the Group of Seven summit had come to a surprisingly uneventful end, President Donald Trump stepped in with two tweets that blew up the whole thing.
The leaders of some of the world's largest economies had worked late into the night to craft a final message from their meeting in Quebec, finding a careful balance between their concerns and Trump's, particularly on trade.
Late Saturday afternoon, Prime Minister Justin Trudeau formally announced that all seven leaders had agreed to the final communique and then took questions about his interactions with Trump.
All of his answers tracked with what he's said in the past, but they set Trump off.
Already halfway through his trip from Quebec to Singapore for his meeting with North Korean Leader Kim Jong Un, Trump tweeted from Air Force One that he had instructed his aides to pull out of the communique, pinning the blame on Trudeau's "very dishonest & weak" approach.
While end-of-summit statements aren't usually world-changers, Trump's move was highly unusual, a sign of aggression toward a host who believed he'd just finished out a successful event and a reminder that with Trump, no deal is final.* SUBSCRIBE FOR FREE UPDATE: Get Fin24's top morning business news and opinions in your inbox.
