To the contrary, Macron told the French press that it was a necessary show of strength, a symbol that France "won't make small concessions, even symbolic ones, while not overhyping things either", according to Politico. "I reminded him of the importance these agreements have for us", Mr Macron said, adding that the pact was also important for job creation and economic development.
But as a 39-year-old who has never held elected office, Macron clearly was excited about the appearance with the USA president, which cemented his status as a new global player - and as a formidable hand-shaker.
The ambassador, whose previous post was as France's ambassador to the United Nations, allowed that he had just sent a memo to Macron advising him on how to handle the American president during their first meeting at the North Atlantic Treaty Organisation summit in Brussels on Thursday. Trump also has a habit of patting the hand of the other person as he shakes hands. Each man gripped each other's right hand so firmly that their knuckles turned white and their jaws seemed to clench.
Weighing in on the tense exchange between the two world leaders, body language expert and retired Federal Bureau of Investigation counterintelligence and counterterrorism operative Joe Navarro said that President Trump's behavior may indicate he does not understand the meaning of a handshake - particularly when meeting other political leaders.
Former reality TV star Trump is known to make visitors flinch with a strong handshake that he often combines with a wrench of the arm to leave his victim off balance.
It is not the first time Trump has caught the world's attention with his macho man grip. According to the AP, Macron noted that the handshake was a "moment of truth" and "it wasn't innocent".
In the video, which was initially shared by Macron himself on Twitter, the French president can be seen walking up the red carpet at the North Atlantic Treaty Organisation summit in Brussels toward a group of world leaders. But the president's body language and that of those around him has spoken volumes.
When Trump went in for the handshake, he was met with an unrelenting response, with Trudeau holding his arm steady and firm against any attempted yank.
A French official told CNN near the end of the G-7 summit that the two had gotten along well and that Trump had told Macron after the French election that he hadn't supported Le Pen.
Mr Macron said he respected Mr Trump's decision to put the Paris agreements under review.
