It was all smiles for a family photo of with G7 countries comprising the United States, Japan, Germany, France, Italy, Britain and Canada in the French resort city of Biarritz on Sunday.
But the smiles and customary French greeting with a kiss on both cheeks, have been overshadowed by more pressing world issues.
European leaders have been trying to quell a confrontation between Washington and Tehran since the U.S. withdrew from the Iran nuclear deal.
Before leaving Washington, Trump stepped up his trade dispute with China, and at a meeting with UK Prime Minister Boris Johnson Trump said his allies "respect" the tariff war.
The world leaders are also faced with the task of figuring out how to unify and tackle major wildfires burning up swaths of the Amazon rain forest.
French President Emmanuel Macron said on Sunday the leaders of the world's major industrialized nations were close to an agreement on how to help fight the Amazon forest fires and try to repair the devastation.
He said they were finalizing a possible deal on "technical and financial help."
