Thursday's conference, called the "World Convergence Summit for Growth," "signals a new willingness on the part of China, the United States, and Europe to engage in a coordinated economic approach," the French presidency said in a statement.

The G7 summit will be held in the Alpine lakeside resort of Evian on June 16-17.

The videoconference will bring together representatives of the G7 (Britain, Germany, Canada, the United States, France, Italy and Japan), China and the International Monetary Fund (IMF).

Brazil, South Korea, India, Kenya and Egypt, which have been invited to the G7 summit, scheduled from June 15 to 17 in Evian, France, will also take part in Thursday's videoconference.

"This summit aims to initiate cooperation between systemic and emerging economies to ease tensions and create the conditions for balanced, sustainable and shared growth," the Elysee said.

The fight against imbalances is "also in the interest of the most vulnerable countries," according to the French presidency, which sees this meeting as "a contribution to the G20" summit scheduled for December in the United States.

China is a member of the G20 but not of the G7, unlike the United States and the largest European economies, which belong to both groups.

Macron is scheduled to meet Canadian Prime Minister Mark Carney on Friday evening in Paris, then Indian Prime Minister Narendra Modi on Sunday in Nice for an event focused on tech.

He will welcome his G7 counterparts on Monday evening in Evian, a spa town in the French Alps on the shores of Lake Geneva.
