Barack Obama, then US president, ordered the seizure of two Russian diplomatic compounds and the expulsion of 35 Russian diplomats in December over what he said was their involvement in hacking the 2016 US presidential election campaign, something Russia flatly denies, according to Reuters.
Russia has said too many American spies operate in Moscow under diplomatic cover and has said it might expel some of them to retaliate over the incident.
"We still hope that our American colleagues will demonstrate a certain political wisdom and political will," Kremlin spokesman Dmitry Peskov told a conference call with reporters when asked about the dispute.
Peskov said any US preconditions to return the property would be unacceptable for Moscow and said Washington's failure to hand back the compounds ran counter to international law.
He declined to discuss what steps Russia would take if the meeting between Ryabkov and Shannon failed to resolve the row.
