US President Joe Biden has agreed “in principle” to hold a summit with Russian President Vladimir Putin to discuss the crisis over Ukraine.
The talks proposed by France will only take place if Russia does not invade its neighbour, the White House said.
The meeting could offer a possible diplomatic solution to one of the worst security crises in Europe in decades.
US officials say intelligence suggests Russia is ready to launch a military operation, which Moscow denies.
The proposal was announced by the French presidency after two phone calls between President Emmanuel Macron and Mr Putin, which went on for almost three hours in total.
The second exchange happened in the early hours of Monday Moscow time, and followed a 15-minute conversation Mr Macron had with Mr Biden.
In a statement that confirmed the proposal, the White House also said Russia appeared to be “continuing preparations for a full-scale assault on Ukraine very soon”, and that the US was ready to impose “swift and severe consequences” should it happen.
Russia has massed more than 150,000 troops close to Ukraine’s borders, according to US estimates.
US company Maxar said new satellite imagery showed multiple new field deployments of armoured equipment and troops from Russian garrisons near the border with Ukraine, indicating increased military readiness.
The Kremlin said Mr Putin blamed the Ukrainian military for the escalation of tensions. Ukraine has rejected this, saying Moscow is engaged in a provocation campaign aimed at creating a pretext for an intervention.
However, the French presidency said both leaders agreed to resume talks through the Normandy Format, a group created to resolve the conflict in eastern Ukraine that includes Russia, Ukraine, France and Germany.
UK Prime Minister Boris Johnson said Mr Putin’s commitments to Mr Macron were a “welcome sign” he might still “engage in finding a diplomatic solution”. But Mr Johnson called on Mr Putin to “step back from his current threats and withdraw troops from Ukraine’s border”.
Earlier, Russia announced the extension of military drills in Belarus, where 30,000 Russian troops are deployed, that were due to end on Sunday. A Belarusian statement blamed the “deterioration of the situation” in eastern Ukraine as one reason for extending the exercises.
Speaking on CNN, Secretary Blinken said “everything we are seeing suggests that this is dead serious” and that “we are on the brink of an invasion”.
“Until the tanks are actually rolling, and the planes are flying, we will use every opportunity and every minute we have to see if diplomacy can still dissuade President Putin from carrying this forward,” he added.
