It also highlighted the necessity for Russia to conduct what it calls a "special military operation" in Ukraine.
In a conference call with reporters, Kremlin spokesman Dmitry Peskov said the idea of Ukraine joining NATO was "the main threat" to Russia which "emphasizes the relevance and urgent need to ensure our security and our national interests," Reuters reported.
Before Russia sent tens of thousands of troops into Ukraine in February, Moscow was demanding legal guarantees that Ukraine never be admitted to the military alliance.
