After five hours of talks with Russian President Vladimir Putin, French President Emmanuel Macron said the coming days will be critical in de-escalating the Ukraine crisis.
During his first Moscow conference with a Western leader since Russian forces massed near Ukraine's borders, Mr Putin signalled that progress had been made.
Moscow has denied any invasion plans.
Western powers, on the other hand, have grown increasingly apprehensive about the likelihood of a conflict.
President Macron, who travelled to Ukraine on Tuesday morning, earlier told reporters in Moscow the coming days would be "decisive" and "require intensive discussions which we will pursue together".
Mr Putin said some of Mr Macron's proposals "could form the basis of further joint steps", stating that they were "probably still too early to talk about".
According to a source in the Elysée Palace, Russia has agreed not to take any further military steps in order to facilitate a possible de-escalation. Further discussions on crucial matters such as Russia's armed units and strategic issues could follow.
The Kremlin, on the other hand, declared on Tuesday that such claims were "not right."
