- And on Saturday morning, Macron was seen greeting Trump, leaning toward the US leader at one point, sparking questions on whether he offered him a peck on the cheek.
- For a moment at the G20 summit Saturday the United States was represented by another Trump, when the president's daughter Ivanka took a seat at the table of world leaders.
- An animated encounter between Merkel and Putin has been making the rounds on social media, with much buzz and speculation about what the two leaders discussed.
From US First Lady Melania Trump's travails to the reserved German Chancellor Angela Merkel's facial twitches, here are some of the anecdotal moments that livened up this year's G20 summit of world leaders in Hamburg.
Star of the summit
Hadrian emerged the star of the summit from the moment his parents swung him over as they embarked from the plane where he proceeded to grab and keep the bouquet meant for his mother.
Mixed day for Melania
US First Lady Melania Trump was due to go on a cruise tour with other spouses of G20 leaders, but was instead trapped at her residence as anti-globalisation demonstrators went on the rampage, smashing shop windows and burning cars.
When she finally emerged, her husband Donald was in talks with Russian President Vladimir Putin.
"There are so many issues on the table... Just about everything got touched upon... Neither one of them wanted to stop" talking, said US Secretary of State Rex Tillerson.
"I believe they even sent in the First Lady at one point to see if she could get us out of there, but that didn't work either... We did another hour. Clearly she failed," he added.
Later that evening, Melania found herself sitting next to Putin who, having already kept her husband for two hours and 15 minutes in talks, appeared equally chatty with her.
Ivanka steps in
For a moment at the G20 summit Saturday the United States was represented by another Trump, when the president's daughter Ivanka took a seat at the table of world leaders.
The 35-year-old former fashion model sat around the table with Chinese leader Xi Jinping, Turkish President Recep Tayyip Erdogan, German Chancellor Angela Merkel and British Prime Minister Theresa May, diplomats and the White House confirmed.
Ivanka had been at the back of the room but "briefly joined the main table when the president had to step out," a White House official told AFP.
That quickly sparked a storm, with historian Anne Applebaum slamming what she called "an unelected, unqualified, unprepared New York socialite" being seen as "the best person to represent American national interests."
