GENEVA/MOSCOW (Reuters) -Don't expect a major breakthrough at a summit on Wednesday between U.S. President Joe Biden and his Russian counterpart Vladimir Putin, a U.S. official said on Tuesday, given relations between Washington and Moscow are their most strained in years.

"We’re not expecting a big set of deliverables out of this meeting," a senior official told reporters aboard Air Force One. The two leaders are expected to talk for four of five hours, the U.S. official said.
