"We condemn any intentions to impose sanctions, consider them illegal, and in any case the principle of reciprocity operates in this area", said Peskov.
In a report last month, U.S. intelligence agencies said Russian President Vladimir Putin likely directed efforts to try to swing the election to then-President Donald Trump and away from now-President Joe Biden.
The sanctions are expected to target more than 30 Russian entities and include the expulsion of at least 10 Russian individuals from the United States, including intelligence officials and diplomats, according to sources briefed on the matter. The breach gave hackers access to thousands of companies and government offices that used the company's products.
It was not immediately clear what, if any, other actions might be planned.
They come amid an already tense relationship between the US and Russia, with US President Joe Biden telling Russian President Vladimir Putin this week that the US would "act firmly in defence of its national interests" regarding Russian intrusions and election interference.
The new sanctions come just after Biden in a phone call with Putin on Tuesday invited him to hold a summit on neutral ground, after tensions between the West and Russian Federation escalated in recent weeks over the conflict in Ukraine.

"A key element of Moscow's strategy this election cycle was its use of proxies linked to Russian intelligence to push influence narratives - including misleading or unsubstantiated allegations against President Biden - to USA media organizations, US officials, and prominent USA individuals, including some close to former President Trump and his administration", the declassified report released by the Office of the Director of National Intelligence stated.
Peskov said on Thursday that any new US sanctions would not increase the chances of such a summit taking place, but said it would be up to the two presidents to decide on the matter.
The Obama administration expelled diplomats from the U.S. in 2016 in response to interference in that year's presidential election.
But it remained unclear whether the actions would actually result in changed behaviour, especially since past measures by the U.S. have failed to bring an end to Russian hacking. The hackers gained access to digital files of several USA government agencies, including the Treasury, Justice and State Departments.
The breach exposed vulnerabilities in the supply chain as well as weaknesses in the U.S. federal government's own cyber defences.
The actions would represent the second major round of sanctions imposed by the Biden administration against Russian Federation.
