The system of security guarantees for Ukraine will be formed on the basis of the best world experience, Head of the President's Office Andriy Yermak said in an interview with Ukrayinska Pravda on Thursday.

"The best of the existing models will be chosen, which will give us a full guarantee of safety. Believe that today, despite the difficult situation, the best specialists are working both at the President's Office and outside the Office. We will take the best world experience, no one will do something in a hurry," Yermak said.

According to him, this will be a "fundamental document" that we are writing together with partners. "We understand that if it appears, it will not be for decades. It must protect Ukraine for centuries," he said.

Answering a question about the rapid entry of Ukraine into the EU, Yermak said: "We are doing everything for this. And I believe in it."
