Russian Foreign Minister Sergei Lavrov, however, said earlier on Wednesday that Mr Stoltenberg had “lost touch with reality”, when asked about Nato boosting its presence near Russia’s borders.
“You know, I stopped taking any view of his statements a long time ago,” Mr Lavrov told the press in Russian parliament, which were broadcast live on social media.
Separately, diplomats from Russia, Ukraine, France and Germany reaffirmed a commitment to the long-standing ceasefire agreement in Ukraine, which had seen Russia-backed rebels seize territory in the eastern Donbas region.
All four nations continue to support the ceasefire “regardless of differences on other issues” related to the 2015 Minsk agreements, a statement published by the French presidency said.
The Kremlin’s deputy chief of staff Dmitri Kozak characterised the eight-hour talks in Paris as “not simple”, and the group is due to meet again in two weeks in Berlin.
