Amazon CEO Jeff Bezos. AP Among all the leaders in tech, Amazon CEO Jeff Bezos probably had the most contentious relationship with President-elect Donald Trump during the campaign.

The two publicly criticized each other on many occasions, with Trump once warning that Amazon would have "problems" if he became president.

So the anticipation was high leading up to Wednesday's tech summit, when Bezos finally got to have his first face-to-face meeting with Trump.

And judging by the way Bezos introduced himself, he clearly wants to make nice with Trump now.

"Jeff Bezos, Amazon.com. Super excited about the possibilities this could be the innovation administration," Bezos said, as Trump went around the table asking the tech leaders to briefly introduce themselves.

Bezos also sent us this statement:

"I found today's meeting with the president-elect, his transition team, and tech leaders to be very productive. I shared the view that the administration should make innovation one of its key pillars, which would create a huge number of jobs across the whole country, in all sectors, not just tech — agriculture, infrastructure, manufacturing — everywhere."

So for now, it looks as if the two men will let bygones be bygones.

Bezos certainly put a lot more thought into his introduction than some of the other CEOs who just gave their title and company name. It's perhaps his way of showing respect to the president-elect, but it could also be seen as a subtle knock on Trump's administration, which is expected to focus more on infrastructure development than on technology innovation.

In any case, Bezos has every reason to extend an olive branch with the incoming administration. Amazon has grown so much in recent years that its business interests are tightly linked to government policies, across areas like sales tax, net neutrality, immigration, and shipping, just to name a few. It's one reason Amazon has significantly increased its lobbying expenditures lately.

Trump's response to the tech leaders was encouraging. He told them to call him and his associates directly if they ever needed anything, applauding the tech sector's accomplishments.

"I'm here to help you folks do well ... we want you to keep going with the incredible innovation," Trump said. "There's nobody like you in the world. There's nobody like the people in this room."

But despite all the nice words that went around, Bezos's facial expression, seen below, alongside Google/Alphabet's Larry Page and Facebook's Sheryl Sandberg, didn't show a whole lot of confidence.
