President Donald Trump and French President Emmanuel Macron are no strangers to the awkward handshake.

But their most recent embrace in Paris on Friday - which lasted a whopping 30 seconds - has been branded the 'most bizarre' yet between the two world leaders.

Body language expert Patti Wood told DailyMail.com that Macron had the upper hand as the pair said au revoir at the conclusion of the US leader's visit to France.

She also described Trump's awkward embrace with France's First Lady on Thursday as 'violent and rough'.

'It's incredibly different, too bizarre for a greeting between two world leaders,' Wood told DailyMail.com.

The epic 30 second handshake battle between Donald Trump and Emmanuel Macron in Paris on Friday was a clear power struggle, a body language expert says

'One thing was the length of time the two men held hands - time communicates dramatically. I believe it lasted 30 seconds, they just didn't let go. That was a power struggle.'

Wood believes Trump had the lower hand right from the start and tried to grip on to maintain he still had power.

'It started with Macron holding his hand palm down. That handshake he offered put Trump immediately in a palm-up, submissive handshake,' she said.

'It made Trump submissive and he lost the power.

'Macron would not let go. He had made the decision ahead of time not to let Trump win the handshake - he kept gripping hard.'

The pair shook hands as Trump departed a military parade during the Bastille Day celebration. They continued awkwardly clasping hands as they walked along the parade route.

At one point, Trump patted Macron's hand and they jerked their hands back and forth in an arm wrestling motion.

Trump was trying to show he still had power by taking Macron's wife's hand midway through their embrace, according to the body language expert

Wood said both leaders have shown in the past they typically pull the other person during a handshake.

'(Trump) likes to pull the person towards them so the hands are right in front of his chest, right over his heart. In this case Macron was attempting to do that and succeeded several times,' she said.

Trump then shook hands with Macron's wife, Brigitte, as he bizarrely continued to shake hands with the French president.

Wood says Trump's behavior was all part of the power struggle.

'Trump did things to not let go, but also to show power,' she said.

'In the bid to regain power, Trump created a bizarre ring-around-the rosy dance with Macron and Brigitte.

'He patted the president's arm, he reached for the wife - that whole interaction was very hard. He took her outside arm and gripped her so tightly. That was just odd.'

Trump held Brigitte in a death grip on Thursday when she greeted him. The body expert described Trump's awkward embrace with her as somewhat 'violent and rough'

She said Trump's actions implied he was trying to show Macron 'that I control your woman'.

'It was a strange, bizarre interaction,' Wood added.

It followed the awkward lingering embrace between the French First Lady and Trump as she and her husband welcomed him and Melania to Paris on Thursday.

'He did that bizarre thing where he jerked her hand up and up - it was violent and oddly rough,' Wood said.

Trump and Macron have a history of handshake battles.

At a NATO summit in Brussels in May, the two world leaders locked hands for so long that their knuckles started turning white.

Macron later called that handshake a 'moment of truth' to show he's not a pushover.
