Russia on Wednesday promised retaliation against Washington in the event of new economic sanctions.
U.S. Republican Senator Lindsey Graham said that Russia and President Vladimir Putin should expect tough sanctions after cyber attacks during the presidential election, won by Donald Trump.
"To be honest, we are tired of lie about the 'Russian hackers', which is being poured down in the United States from the very top," Foreign Ministry spokeswoman Maria Zakharova said.
She also called reports of possible new sanctions a "provocation directed by the White House".
Earlier this month, Republican and Democratic senators including Graham called for a bipartisan panel to investigate cyber attacks against the United States by foreign countries, with a focus on Russia's alleged efforts to influence the U.S. presidential election.
U.S. intelligence agencies concluded that Russia tried to influence the Nov. 8 election by hacking individuals and institutions, including Democratic Party bodies.
However, Russian officials have denied accusations of interference in the election.
The Obama administration had earlier reaffirmed its commitment to maintaining sanctions on Russia over Crimea with new financial restrictions announced on December 20 on Russian businessmen and companies.
While the sanctions were not unusual, the timing was, as Donald Trump's U.S. election victory has created doubts about the future of U.S. policy towards Russia and for a united approach to sanctions given his apparently softer line on President Vladimir Putin.
