German Chancellor Angela Merkel found the contentious Group of Seven summit with U.S. President Donald Trump a "sobering" and "depressing" experience but said European leaders won't be "taken advantage of" on trade.
She conceded in an interview on German public television Sunday that the meeting's outcome "wasn't a great thing."
"I have spoken of a sobering experience, which for me is a lot," she added.
Merkel, French President Emmanuel Macron and the other leaders clashed with Trump over steel and aluminum tariffs as well as his decision to abandon a deal with Iran to limit its nuclear program.
The group managed a common statement in which they agreed to disagree on some issues, only to have Trump disavow the document in a tweet after leaving the meeting.
Merkel said that "taking it back by tweet was of course sobering and also a little depressing."
She said the European Union would "act" against the U.S. trade measures, which European leaders regard as going against the rules of the World Trade Organization.
