"Because we are talking about the future of our country, we don't want to be excluded from the negotiations. We don't want to be a card (to be played).

She added that no longer believes in gentleman's agreements anymore, noting Russia had violated an earlier deal - the 1994 Budapest Memorandum on Security Assurances, under which Ukraine, Belarus and Kazakhstan gave up nuclear weapons in exchange for assurances of territorial integrity - when it annexed Crimea. Zerkal reiterated Ukrainian President Petro Poroshenko's call for the West to maintain sanctions imposed against Russia over the 2014 annexation of Crimea and its support for the separatists in the Donbas. "This is the only tool we all have in order to prevent [Russian President Vladimir] Putin from a further spree of aggression," she said.
