"Russia will demand that NATO legally enshrine the alliance's non-expansion to the East, the Russian Embassy in Belgium told Izvestia. Moscow will also demand the repeal of the decisions of the 2008 Bucharest Summit."

It seems this is a matter of international law. The US openly disregards international law and, in general, the rights and sovereignty of any other country. What and with whom does Russia want to "legally enshrine"?
