"We still hope that our American colleagues will demonstrate a certain political wisdom and political will", Kremlin spokesman Dmitry Peskovsaid on a Monday conference call with reporters.
Earlier on Monday, Russian President Vladimir Putin's spokesman, Dmitry Peskov, told journalists that Russian property in the U.S. should be returned to Moscow without any conditions.
Former US President Barack Obama in December ordered the seizure of two Russian government residential compounds in Maryland and NY and expelled 35 Russian diplomats and suspected spies.
Peskov said that any USA preconditions for the return of the property would be unacceptable for Moscow, and that Washington's actions contradicted global law. "Kremlin, as it is, does not really participate but as you know this issue was raised by President [Vladimir] Putin during his G20 meeting with President Trump in a quite straightforward manner".
Talks held Monday between Russia's Deputy Foreign Minister Sergey Ryabkov and USA counterpart Thomas Shannon failed to settle the dispute.
Obama announced the United States was shutting down the residential complexes in December at the same time as he expelled 35 Russian diplomats for spying.
Relations were further damaged by Moscow's alleged interference in the US election. USA officials played down chances for a breakthrough, especially since Russian Federation abruptly canceled the diplomats' last scheduled meeting in June in response to new Ukraine-related sanctions.
The second round of Russian -American consultations between deputy foreign ministers took place in Washington on July 17.
President Donald Trump has said that removal of the sanctions, including the return of the properties, will not occur until issues regarding Russian Federation and its relationships in Ukraine and Syria are resolved.
Russia's made increasingly strident demands for the issue to be resolved since it was discussed at Trump and Putin's first official meeting, which lasted more than two hours at the Group of 20 summit in Hamburg this month.
Foreign Ministry spokeswoman Maria Zakharova complained last week that the USA was also refusing to issue visas for Russian diplomats to replace those expelled.
