President Emmanuel Macron met billionaire businessman Elon Musk on Monday (May 15) to discuss future investment projects, as the French leader hosts a conference aimed at persuading business leaders to put their money in France.

Macron hosted the world’s second richest man, who is the chief executive of electric car firm Tesla, social media company Twitter and cosmic exploration outfit SpaceX, six months after their last encounter in the United States, his office said.

They met at the Elysee Palace before both head to Versailles for the latest edition of the president’s Choose France conference where Macron seeks to drum up investment in the country.
