Foreign Ministry spokesman Oleg Nikolenko said this in a comment to Ukrinform.
"Of course, for the sake of peace and saving the lives of our citizens, Ukraine is ready to enter into any format of dialogue with countries and international organizations. At the same time, Ambassador Prystaiko rightly noted in an interview that the prospect of NATO membership is enshrined in the Constitution of Ukraine, but Ukraine is not currently a member of NATO or another security alliance. Therefore, the issue of security guarantees becomes a key issue for our country," he said.
According to Nikolenko, the best such guarantee would be Ukraine's immediate accession to NATO.
"But threats to Ukraine exist here and now, so finding an answer to the question of guarantees becomes a fundamental urgent task. At the same time, no decision can be made contrary to the Constitution of Ukraine," Nikolenko said.
Prystaiko in an interview with BBC Radio 5 Live suggested that Ukraine may refuse to join NATO if circumstances so require.

Ukraine's ambassador to the UK Vadym Prystaiko has told @StephenNolan his country might agree not to join @NATO if it would avert war with Russia.
It would mean the country abandoning a goal written into its constitution.
