"Continued US allegations of the so-called Russian interference in the US domestic affairs also remain in the category of extremely problematic aspects, where it’s impossible to find common ground," Ryabkov said.
The US media are still boiling over Russia's alleged meddling in US affairs, including in the 2016 presidential election that resulted in Donald Trump's victory.
The fact of interference has never been proven. The Democrats, however, continue to insist that the collision did happen during the US presidential campaign.
