Russian negotiator Vladimir Medinsky is speaking following yesterday's talks in Istanbul, at which Russia said it would pull back from Kyiv and Chernihiv, APA reports citing BBC.
He says talks with Ukraine are continuing but adds that Russia's position on Crimea and the Donbas region has not changed.
Russia annexed Crimea from Ukraine in 2014, while parts of the eastern regions of Donetsk and Luhansk - collectively known as the Donbas - are held by Russian-backed separatists.
But Medinsky says Ukraine has stated a willingness to meet Russia's core demands. He says if it sticks to its promises then "the threat of a Nato stronghold" in Ukraine will be removed.
