Moscow has long called for the two sides to hold negotiations aimed at reducing tensions over the nuclear and missile programme North Korea is pursuing in defiance of years of UN Security Council resolutions.
"Russia's readiness to clear the way for de-escalation is obvious," Kremlin spokesman Dmitry Peskov said in a phone call with reporters.
Foreign Minister Sergei Lavrov called on Monday for Washington and Pyongyang to start negotiations, saying Russia was ready to facilitate such talks.
Though US diplomats have said they are pursuing a diplomatic solution, President Donald Trump has said Pyongyang must commit to giving up its nuclear weapons before any talks can begin.
The UN Security Council unanimously voted to impose new sanctions on North Korea on Friday in response to its recent intercontinental ballistic missile test, a move North Korea called an act of war, tantamount to a complete economic blockade.
