Callas accused Russia of trying to impose its negotiating terms on the West.
The head of EU diplomacy said that Moscow seeks to obtain maximum concessions through pressure and ultimatums.
In her opinion, the West's willingness to compromise only strengthens Russia's negotiating position.
Callas called on European countries not to provide Moscow with additional leverage and not to accept Russian demands as a basis for a future security system.
