The head of the Ukrainian President's Office Andriy Yermak said that Kiev continues to consult with its partners on a security guarantee framework, local online media outlet LB.ua reported Monday.

"We continue permanent consultations... As of today, many countries from different continents have expressed their desire to be future guarantors," Yermak was quoted by the media outlet as saying.

Speaking on the possible format of the security guarantee, the official said it should include a single multilateral framework deal between all the guarantor states and a separate bilateral agreement between Ukraine and each guarantor.

The guarantor countries must ratify the framework agreement before taking effect, Yermak said.

At the peace talks with Russia held in the Turkish city of Istanbul in late March, Kiev proposed signing a new international security guarantee treaty, which enshrines obligations for the guarantor countries to provide Ukraine with military assistance in the event of an attack.
