DONALD Trump used a puffed up chest and slow walk to size-up and intimidate his fellow G7 leaders, according to our body language ace.
Expert, Darren Stanton, says the US president tried to "dominate the room" as he clashed with world bosses over Russia and trade tariffs.
Furious Trump threatened to snub his allies and leave the G7 Summit several hours early - so he can prepare for Tuesday's showdown with Kim Jong-un.
But our body language pro reckons Trump spoke more than words when he went head-to-head with leader's of other nations in Canada.
Darren, who has followed President Trump since I worked on the US primary elections, says he is renowned for his bone crusher handshake.
He told us: "Upon entry to the summit, I notice Trump very much positioned himself front and centre.
"It's all about power and assertion, he most definitely wants to be perceived on the world stage as the top man."
He also noted more 'power poses' as Trump greeted fellow world leaders.
Darren added: "We can see Trump pulling back his shoulders to make himself puff out more which is saying 'look I'm here, I'm the powerful one.'
"We see Angela Merkle to Trump's left and he has his shoulders back, chest puffed out and his feet astride, which is saying 'I'm going to dominate the room.'
Darren says Trump entered the chamber with a "strange walk" and sat with his legs astride as a power gesture to mean the more space we occupy the more powerful we are
He says: "It's slow and laboured, like he is sizing up the room, and considering his prey."
Trump walks into the room flanked by Angela Merkel and Justin Trudeau, with the latter flashing Trump "a micro-expression of disgust" for being left out of the conversation.
Darren says this year's summit has a much more intense atmosphere than previous meetings.

He adds: "Trump looks like he has come with an agenda of his own and he fully intends to get his point across.
"His posture, body language and demeanour is conveying a lot of power gestures to drive the others in to submission.
Something tells me its going to be a very interesting summit."
