In the footage shared on Macron's own Twitter feed, the new French President can be seen walking towards a gaggle of world leaders at yesterday's (Thursday) Nato summit in Brussels, including Angela Merkel and Mr Trump.
But in Europe, Trump has faced a far cooler reception and has been eager to go on the offensive.
He said Trump had a few days ago signed a United States budget proposal to hike spending on U.S. forces in Europe by 40 percent, in what Stoltenberg called "the best demonstration of commitment to the alliance".
While Balkan media reacted with indignation - running headlines like "America First" - Markovic shrugged off the slight.
The White House believes that Trump has made personal breakthroughs with his peers, having now met one-on-one with all the leaders of G-7.
Russian Federation will be on the agenda and there were signs that "behind the scenes Trump is prepared to talk about things", Lewis said. Many saw this encounter with Japanese PM Shinzo Abe as awkward at best.
As he tried to reach the front of the group, Montenegro's Prime Minister Dusko Markovic was standing in his way. The other leaders are divided over his spending demands, as well as over how much intelligence to share with Trump's troubled administration. We're not playing cutesy with this.
"That was probably a very wise choice", he said.
"It's a big problem, it's a world problem, but it will be solved at some point".
"As for climate, well, President Trump can assert his position", Macron said after Thursday's meeting. He's finishing his foreign tour there at the G7 meeting. And we have a lot to discuss, including terrorism and other things. "There is no relationship we cherish more than the Special Relationship between the United States and the United Kingdom". He wrote that his meeting with Trump was "constructive" and "direct". What the Sicily stay will likely not offer: a news conference, as Trump appears set to defy presidential tradition and not hold one during the entire trip.
Footage showing the leaders caught Trump pushing his way past Prime Minister Dusko Markovic, then confidently adjusting his suit as he emerged in the front of the group, closer to North Atlantic Treaty Organisation head Jens Stoltenberg.
Ms Merkel, who stood emotionless during the speech, earlier issued her own challenge to the U.S. president, saying that member states including Germany had already pledged to work toward the 2 per cent target by 2024 and that outlays on security more generally also count toward the goal.
The president opened his day with a meeting with leaders of the European Union, another alliance he criticized during the campaign.
European Council President Donald Tusk said terrorism was one of the main topics between EU officials and Trump during his visit to Brussels, especially in the wake of the Manchester pop concert bombing.
A spokesman for Mr Juncker, president of the European Commission, which had been negotiating a free trade deal with Washington known as the TTIP before Mr Trump's upset election victory, said the two sides would work to increase trade. Declining to do so is significant as Trump has threatened to remove the United States from the alliance, which was formed in 1949.
Macron said he spoke with Trump about the Paris agreement to reduce greenhouse gases.
