WASHINGTON (CNN) -- President Donald Trump on Saturday accused Canadian Prime Minister Justin Trudeau of making "false statements" and said that the US will not endorse a G7 communique.
Trump's tweets taking aim at the leader of a country that has long been a US ally came after the President left the G7 summit in Canada to travel to Singapore ahead of a planned diplomatic meeting with North Korean Leader Kim Jong Un.
Earlier in the day, Trudeau said during a news conference that Canada will "move forward with retaliatory measures" on July 1 in response to the Trump administration's decision to impose tariffs on steel and aluminum imports from Canada, the European Union and Mexico.
"I have made it very clear to the President that it is not something we relish doing, but it something that we absolutely will do," Trudeau said. "Canadians, we're polite, we're reasonable, but we also will not be pushed around."
Trump addressed the subject of international trade during an impromptu news conference at the summit on Saturday, saying that he does not want to see other countries take advantage of the US over trade.
"It's going to change," he said. "Tariffs will come way down. We're like the piggy bank that everybody is robbing and that ends."
He added, "if they retaliate, they're making a mistake. We have a tremendous trade imbalance."
