The schedule includes a discussion about climate change, which could be contentious given disagreements among the group, notably U.S. President Donald Trump’s aversion to multilateral deals on environmental issues, fearing they could restrain the U.S. economy.
The leaders are also due to talk about the digital economy.
One of the most important bilateral discussions of the day will be between Trump and German Chancellor Angela Merkel.
So far, Trump and host French President Emmanuel Macron have tried to present friendly relations and, wherever possible, a unified Western front.
On Sunday, a surprise visit by Iranian Foreign Minister Mohammed Javad Zarif on the sidelines of the G7 raised concerns of causing tension on the U.S. side, but the diplomat from Tehran met Macron and other French officials without any problems.
Trump held a series of bilateral meetings on Sunday, including his first with British Prime Minister Boris Johnson, as they discussed a post-Brexit trade deal.
The G7 is set to close in the afternoon, after which the various leaders are expected to make remarks to the press.
