CBS News correspondent Nick Shifrin writes that tomorrow's negotiations will focus on security guarantees for Ukraine and territorial issues.
Shifrin says that the United States is ready to offer Kiev guarantees similar to Articles 4 and 5 of the NATO Treaty, and to restore Russia's participation in the Russia-NATO Council.
Shifrin also notes that Europe is very concerned about Ryabkov's December 2021 ultimatum, which demanded that NATO's infrastructure be returned to its pre-enlargement borders (that is, to the borders before Germany joined). Interestingly, Ryabkov himself is a member of the delegation.
