The US President Donald Trump also sat down with Russian President Vladimir Putin in one of the more highly anticipated sideline meetings of the summit.
At the onset, the two leaders expressed willingness to improve relations that are said to be at the worst level since the Cold War.
Trump said, "We have many things to discuss, including trade and including some disarmament, some little protectionism perhaps, in a very positive way.
Putin said, "Our teams have been working together and this gives us a great opportunity to follow up on our meeting in Helsinki."
This was their first one-on-one in almost a year, and relations had considerably soured since then.
Domestically, the alleged Russian meddling in the 2016 US presidential election has continued to dog Trump.
And the two parties seem far apart on another major issue...nuclear disarmament. The future of two key agreements are in doubt.
