“The key issue for our country is the issue of security guarantees.

Undoubtedly, the immediate admission of Ukraine to the alliance would be the best such guarantee, ”RIA Novosti quotes Nikolenko.

He noted that the words of Ukrainian Ambassador Prystaiko about NATO were taken out of context.

Earlier, Ukraine's ambassador to London, Vadim Prystaiko, admitted that Kiev might abandon its aspiration to join NATO in order to "avoid war."

Serhiy Nikiforov, a spokesman for Ukrainian President Volodymyr Zelensky, said the Ukrainian ambassador needed to explain the words about renouncing NATO membership for the sake of peace.

He also said that Ukraine's aspiration to join NATO and the EU is enshrined in the Ukrainian Constitution.
