In an interview Sunday on German public television, Merkel also says European leaders won't be "taken advantage of" on trade.
That wrestling cry would have been an apt announcement at the G-7 summit, what with the USA and other heads of state at each other's throats using the thrust and parry of rude remarks and social media to pummel each other.
"Very dishonest & weak", Trump said, adding that recently imposed United States tariffs on imports of Canadian steel and aluminium were in response to similar measures imposed on American dairy products by Canada. "The differences in opinion have not been taken off the table".
Mr Navarro said Mr Trump "did the courtesy to Justin Trudeau to travel up to Quebec for that summit".
Trudeau says the U.S., Canada, Britain, France, Germany, Italy and Japan figured out "consensus language" they could all agree to. In the USA version, we see Mr Trump face on, apparently calm, leaning back confidently with a sceptical, nearly sarcastic air, his arms crossed in a rebuff to the other leaders, bent towards him pleadingly.
In her first takeaway from the contentious meeting, Merkel expressed consternation about the US president's backtracking on the summit's final statement, while emphasizing that she'll keep talking with Trump.
The chancellor also announced during Sunday's interview that, just like Canada, the European Union was also preparing counter-measures to Trump's steel and aluminum tariffs.
Donald Trump and Justin Trudeau have been at loggerheads over trade tariffs
During a rare solo news conference earlier Saturday, Trump said he pressed for the G7 countries to eliminate all tariffs, trade barriers and subsidies in their trading practices.
Just as the G7 meeting of the world's leading industrialised nations had seemed to weather Mr Trump's threats of a trade war, the president backed out of the group's joint statement that Mr Trudeau said all the leaders had come together to sign.
Even so, dialogue with the United States president must continue and global partnerships aren't over, she said.
Differences over trade tariff disputes and calls to re-admit Russian Federation have overshadowed a summit attended by leaders from from seven of the world's wealthiest nations in Canada.
"There are good reasons on our side to continue to fight for it but we can't count on it anymore", she said.
"If they retaliate, they're making a mistake", Trump said. Japanese Prime Minister Shinzo Abe, his arms crossed, appears to stare at French President Emmanuel Macron, who is barely visible in the photo but appears to be speaking.
"He held a press conference and he said the U.S.is insulting".
