“Ukraine's membership in both alliances is a matter of time, because we are a natural part of the European and transatlantic community,” he said in an interview with the German newspaper Die Zeit.

According to the Ukrainian diplomat, Kiev understands skepticism about the EU's eastward expansion.

He noted that in the coming years, the EU will not be able to promise Ukraine membership, but the state will continue its course towards rapprochement with Europe at the economic and legal levels.

“If you don’t believe in something, then you should not try,” added the head of the Ukrainian Foreign Ministry.

Earlier, Kuleba expressed confidence that Ukraine can be admitted to the European Union and NATO, and with unfinished reforms under the guarantees of their implementation.

The Russian Foreign Ministry called Ukraine's entry into NATO "extremely dangerous" step.
