On February 21, 2022, in pursuance of the assignment by Ukrainian President Volodymyr Zelenskyy and in accordance with Article 6 of the Memorandum on security assurances in connection with Ukraine's accession to the Treaty on the Non-Proliferation of Nuclear Weapons (Budapest Memorandum) of December 5, 1994, the Ministry of Foreign Affairs of Ukraine sent official requests demanding immediate high-level consultations between Ukraine and the countries participating in the Budapest Memorandum and the guarantors of Ukraine's security regarding urgent actions to reduce tensions and ensure Ukraine's security.

The request for consultations refers to the continuing violation by the Russian Federation of its obligations under the Budapest Memorandum, in particular:

– violation of the obligation "to  refrain from the threat or use of force against the territorial integrity or political independence of Ukraine, and that none of their weapons will ever be used against Ukraine except in self-defense or otherwise in accordance with the Charter of the United Nations” (paragraph 2 of the Memorandum) 

- violation of the obligation "to seek immediate United Nations Security Council action to provide assistance to Ukraine, as a nonnuclear-weapon State Party to the Treaty on the Non-Proliferation of Nuclear Weapons, if Ukraine should become a victim of an act of aggression or an object of a threat of aggression in which nuclear weapons are used” (paragraph 4 of the Memorandum). 

Depending on the fact of these consultations and their results, Ukraine will determine further measures to ensure its own security in accordance with its national interests in the face of Russian aggression, the norms of international law and national legislation.
