The 2018 summit ended with Trump assailing his Canadian hosts on social media as he departed on Air Force One, saying he had instructed the U.S. officials who remained in Quebec to oppose the G7 joint statement endorsed by the leaders of Japan, France, the United Kingdom, Italy, Germany and, of course, Canada.

U.S. President Donald Trump said “not so much” is holding up an economic and security deal with Canada as he began his first full day at the Group of Seven summit, a forum he added should consider expanding to include China. Mr. Trump said Canada and the United States will see if they can resolve their differences Monday.
