NATO's refusal to expand further should be documented, Russian President Dmitry Peskov's press minister told Channel One.
"Of course, behind such important words for us there must be actions to document the non-enlargement of NATO," he said (quoted by Interfax).
Moscow, Peskov continued, had already been assured that NATO would not expand eastward, but after that the alliance continued to accept new members, and did so 5-6 times.
