Former President Barack Obama ended a five-day international trip in Paris, where he had lunch with French President Emmanuel Macron and gave a speech to business leaders.
Obama arrived at the presidential Elysee Palace at midday on Saturday. The area was placed under high security.
The French presidency said the private lunch included a presentation about the Obama Foundation. No journalists were allowed at the meal.
Earlier Saturday, Obama discussed climate issues with Paris Mayor Anne Hidalgo. He later met with former French President Francois Hollande.
His evening speech, organized by a club for leaders from the internet and communications industries, was on the theme, “Fear Less, Innovate More.”
Obama was in China and India before he arrived in France.
