Leaders of the Group of Seven (G7) countries will hold an extraordinary leaders summit by video conference on Monday to discuss the COVID-19 outbreak, French President Emmanuel Macron said.

"Following my call with Donald Trump and all G7 leaders, we agreed to organize an extraordinary Leaders Summit by video conference on Monday on Covid-19. We will coordinate research efforts on a vaccine and treatments, and work on an economic and financial response," Macron wrote on Twitter.

The meeting comes as the world continues to record COVID-19 cases, with the World Health Organization (WHO) reporting more new cases outside China in recent weeks.
