French President Emmanuel Macron met with billionaire Elon Musk to cap off his visit to the U.S. this week. 

Macron spent an hour talking with Musk, current CEO and owner of Twitter, and the pair discussed a number of topics, from green energy targets to concerns about content moderation on social media. 

"In accordance with our ambition to decarbonize and reindustrialize France and Europe, I discussed today with @elonmusk on future green industrial projects, in particular on the manufacture of electric vehicles and batteries," Macron wrote on Twitter of the "clear and honest" talks. 

"Transparent user policies, significant reinforcement of content moderation and protection of freedom of speech: efforts have to be made by Twitter to comply with European regulations," Macron also wrote after the meeting.
