Any settlement to the war in Ukraine will require the participation of the European Union, says Kaya Callas. AFP. "We cannot say how and when Ukraine and Russia will conclude a peace agreement," said the EU's foreign policy chief. But "in order to implement any agreement, the European Union should be a party to it," she added after a meeting of the foreign ministers of the Baltic Sea countries in Warsaw. According to Callas, quoted by Reuters, Putin has no veto on European security issues, and Ukraine should be fully integrated into the European security architecture. "We already have a European security architecture. NATO and the European Union are playing their role. We must ensure the inclusion of Ukraine in this architecture," she said.
