Russian President Vladimir Putin has ruled out a tit-for-tat response after the US expelled 35 Russian diplomats amid a row over hacking.
He said Russia would not “stoop” to the level of “irresponsible diplomacy” but would work to restore ties with the US under President-elect Donald Trump.
Russia’s foreign ministry had formally asked Mr Putin to expel 35 US envoys.
The country denies involvement in hacking related to the US election, calling US sanctions “ungrounded”.
Prime Minister Dmitry Medvedev accused the outgoing US administration of President Barack Obama of ending in “anti-Russian death throes”.
