Kremlin spokesman Dmitry Peskov accused Washington of fuelling tensions over Ukraine - repeating Moscow's line that the crisis is being driven by U.S. and NATO actions rather than by its own build-up of tens of thousands of troops near the Ukrainian border.
Western states accuse Russia of planning a new attack on Ukraine, which it invaded in 2014. Moscow denies any such plan but says it could take unspecified military action unless demands are met, including a NATO promise never to admit Kyiv.
NATO said on Monday it was putting forces on standby and reinforcing eastern Europe with more ships and fighter jets. Russia denounced the moves as Western "hysteria".
Peskov said President Vladimir Putin would talk this week to his French counterpart Emmanuel Macron, who is also planning to speak with Ukrainian President Volodymyr Zelenskiy.
Russia is awaiting a written U.S. response this week to its list of security demands it has presented, some of which Washington has dismissed as non-starters.
Peskov said the U.S. troop alert did not affect negotiations because the current phase of talks had been completed.
