French President Emmanuel Macron is seeking to take the lead of the European brigade against U.S. President Donald Trump at the summit of the Group of Seven wealthy countries in Canada.

Macron called a meeting Friday with German Chancellor Angela Merkel, British Prime Minister Theresa May, new Italian Premier Giuseppe Conte and top EU officials just before the G-7 opening.

He told reporters the United States' attitude must lead other nations to "reforge the European front."

European leaders criticize the U.S. decision to impose protectionist tariffs on steel and aluminum and to exit the Iran nuclear deal and the Paris climate agreement.

Tweeting in English, Macron stressed: "No leader is eternal. We inherit commitments which are beyond us. We take them on. That is the life of nations."
