"We would welcome the withdrawal of Russian troops on the border with Ukraine, as this would be a step in the right direction. But for the moment, we have not seen major and significant movements yet," a NATO official told AFP.
The Kremlin said on Saturday that Putin had ordered the pullback of 17,600 servicemen who had participated in summer drills in the southern Rostov region on the border with Ukraine.
But the Nato official said: "There is still a large and capable force sitting on the border of Ukraine and heavy equipment still has to be pulled back.
"As NATO leaders made clear at the Wales summit (in September), Russia must end its support for militants in eastern Ukraine, withdraw its troops and stop its military activities along and across the border with Ukraine.
