Polish Foreign Minister Sikorski said that Ukraine currently has an advantage on the front, and it is impossible to talk about any post-war order without the participation of the Ukrainian authorities. "It is not possible to impose a decision on Ukraine without its consent and presence at the negotiating table. Just as European security cannot be a subject of negotiations without our participation. The countries of the eastern flank will be the most affected by the terms of a possible agreement, but they can also contribute a particularly important point of view regarding the perception of threats from Russia," he added.
