The President's Office hopes to approve the procedure for Ukraine's NATO accession at the Alliance summit in Vilnius in July.

"The document (on Ukraine, - ed.) must definitely be approved at the NATO summit. We need an answer to our NATO application. Therefore, this document should define a clear path for us to join, without additional procedural steps," Andrii Sybiga, the deputy head of the Administration of the President of Ukraine, answered "European Pravda's" question.

Last week, NATO Secretary General Jens Stoltenberg announced that he had invited President Volodymyr Zelenskyy to the NATO summit in Vilnius.

Stoltenberg expressed hope that new steps and long-term support for Ukraine will be agreed at the summit.
