President Biden and Russian President Vladimir Putin held their first face-to-face meetings today at a historic summit in Geneva.

Putin described the summit as "constructive," and told reporters US and Russian ambassadors will return to their diplomatic posts and both countries will begin consultations on cybersecurity

President Joe Biden struck a realistic, but optimistic tone when describing his summit with Russian leader Vladimir Putin — and what happens next.

Biden said the upcoming months would serve as a "test" on whether their discussion today would prove to bring the nations closer to progress.

"That's going to be the test. I am not sitting here saying because the president and I agreed that we would do these things that all of a sudden it's going to work. I'm not saying that. What I am saying is I think there's a genuine prospect to significantly improve the relations between our two countries, without us giving up a single, solitary thing based on principle and our values," Biden said.

Biden noted that there were no "threats" during today's summit.
