Europe will not let Trump do "whatever he pleases", the German chancellor said, adding that "we will not allow ourselves to be deceived again and again".
President Donald Trump drove the wedge splitting Washington from its Western allies even deeper on Friday (June 8) with a spontaneous call for Russian Federation to be readmitted to the G-7 club.
"We seem to want to punish our allies and befriend our enemies", said Tennessee Republican Sen.
Tweeting in English, Macron stressed: "No leader is eternal". It's not just that Trump has repeatedly denigrated North Atlantic Treaty Organisation and the European Union.
Earlier in the day, the USA leader tweeted that he had instructed his representatives not to sign the statement, hours after the summit's host, Canadian Prime Minister Justin Trudeau, announced all countries had supported it.
As befits his role as annual chairman of the G-7, Canadian Prime Minister Justin Trudeau's picture is taken from the side, impartially showing Mr Trump dealing with his counterparts as equals. German Chancellor Angela Merkel is in a stare down with Trump, while Macron is clasping the table, exasperated.
The communique addresses trade, economic growth, national security and sustainability, and acknowledges that "free, fair and mutually beneficial trade and investment, while creating reciprocal benefits, are key engines for growth and job creation". And he prefers autocrats like Putin to democrats like Germany's Angela Merkel and Macron. This was taken as a direct challenge to Merkel (a conservative but not a populist).

The negotiators included agree-to-disagree language on climate change and on an global commitment to reduce plastics in the world. On Saturday, Trump repeated his desire to have a sunset clause in an updated NAFTA deal, a demand Trudeau rejected again.
Macron also tweeted Saturday a photo of the other leaders and aides surrounding Trump, who was one of just two people sitting.
Trump argued that Moscow was too important to isolate.
Yet Trump has displayed little taste for pushing back against strongmen with whom he holds summits.
European Union nations' failure to speak and act with one voice overseas is a "danger", Merkel warned, as is the fact "that we have no collective approach to the question of managing migration", vital if freedom of movement within Europe's borders is to be upheld. "The president is at ease with all of these tough issues". Thomas Wright, a senior fellow at the Brookings Institution, told reporters that for Trump's first 500 days, "these countries generally were bent over backwards not to criticize President Trump".
Trump has invoked a United States national security provision to unilaterally impose tariffs on imports of foreign steel and aluminum, to the outrage of his allies, who have retaliated with a threat of their own, more targeted, sanctions. He is leaving himself alone without allies.
"America stands very much alone as they enter this G-7", Heather Conley, director of the Europe program for the Center for Strategic and International Studies, told reporters on a press call.
