Mr Trump has told leaders that trade as at top of the his agenda for the G7 Summit. He then took questions from reporters for almost 20 minutes, where he threatened to terminate the North American Free Trade Agreement if he can't make a better deal with America's neighbors.
Trump fired back, tweeting, "Please tell Prime Minister Trudeau and President Macron that they are charging the USA massive tariffs and create non-monetary barriers". Trump said the tariffs are necessary for national security. "Not fair to the PEOPLE of America!"
"We have massive trade deficits with nearly every country".
President Trump seemed unconcerned about ruffling a few feathers Friday at the annual Group of Seven nations summit in Canada.
In an interview Sunday on German public television, Merkel also says European leaders won't be "taken advantage of" on trade.
Leaders of the G7 nations spent hunting for a face saving formula to mask the deep rift inflicted on the Western alliance by US President Donald Trump's assault on global trade rules. "Everyone agreed, including President Trump".
Macron launched the offensive on Thursday at a joint news conference with Canadian Prime Minister Justin Trudeau.
He made the comment at the White House yesterday after hours of further escalating his rhetoric against long-time allies over USA trade practices.
"We've had really a very good relationship, very special", the U.S. president said of Macron, a day after the two leaders had exchanged terse messages on Twitter.
The German government was not the only ally to lash out at the U.S. president before the Canada meeting.
The decision led to a "terrible" call between Macron and Trump that became testy, CNN reported.
Trump wasted little time in launching a retaliatory Twitter strike, tweeting out hours later that Macron and Canadian Prime Minister Justin Trudeau "are charging the United States massive tariffs and create non-monetary barriers".
Macron, however, was unsuccessful in his mission to convince Trump not to pull out of the Iran nuclear deal, dealing a blow to U.S. -France relations.
Trump made the comments in tweets from Air Force One as he headed to Singapore for his summit with North Korea's Kim Jong Un.
But that means he will miss a working session among the leaders on climate change and clean energy, as well as talks among the G7 and poorer countries focused on the health of oceans.
However, Maas also warned that Europe should not adopt an adversarial attitude towards the United States as a whole.
