Top officials from NATO and Russia gathered behind closed doors on Monday for a meeting of the NATO-Russia Council at the military alliance's headquarters in Brussels.
The council, NATO's only current channel for dialogue with Russia, last met in July - prior to the election of US president-elect Donald Trump, who has raised eyebrows for his repeated praise of President Vladimir Putin despite Russia's increasing aggression toward Washington.
NATO Secretary General Jens Stoltenberg is expected to make a video statement after the meeting.
Topics related to European security, including Ukraine, are expected to be discussed. NATO and Russian military exercises along NATO's Eastern European flank could be a topic of discussion.
"We expect an open discussion of Europe's security issues," Russia's NATO ambassador Alexander Grushko said, according to state news agency TASS.
Lithuania, Latvia, Estonia and Poland - all former Soviet republics or satellite states - have expressed anxiety about Russia since the country annexed Crimea in 2014. NATO plans to station several thousand soldiers in the four countries next year.
The military alliance suspended all practical cooperation with Russia in April 2014, when relations between the two sides reached their worst point since the Cold War over Russia's annexation of the Crimea and its support for separatists in eastern Ukraine. NATO kept channels for political dialogue open at the time.
The first meeting of the NATO-Russia Council following that suspension was in April 2016 and the last council meeting took place in July.
