Armored vehicles patrol Geneva before Biden-Putin summit

U.S. President Joe Biden and Russian President Vladimir Putin face off on Wednesday in their first meeting since Biden took office with wide disagreements likely and expectations low for any breakthroughs.

Both have said they hope their talks in a stately lakeside Geneva villa can lead to more stable and predictable relations, even though they remain at odds over everything from arms control and cyber-hacking to election interference and Ukraine.

"We're not expecting a big set of deliverables out of this meeting," a senior U.S. official told reporters aboard Air Force One as Biden flew to Geneva, saying the two are expected to talk for four or five hours starting at around 1 p.m. (1100 GMT).

Relations have deteriorated for years, notably with Russia's 2014 annexation of Crimea from Ukraine, its 2015 intervention in Syria and U.S. charges - denied by Moscow - of its meddling in the 2016 election that brought Donald Trump to the White House.
