"This law, which is still a bill, to be more precise, as far as we understand and according to the information we have, is of a very declarative nature. There is an article where the Russian Federation is called an aggressor, and there is no mention of Minsk agreements there. From the legal perspective, of course, such a wording can neither de jure nor de facto be acceptable for us," Peskov said.

According to him, calling Russia an aggressor state contradicts the letter and spirit of Minsk accords as there is "no such definition in the Minsk agreements, while the Russian side is a signee, namely, the guarantor of these Minsk agreements."

"There is a legal contradiction taking place, and we are stating this," he said.

At the same time, Peskov said that the extension of the "special status" of the occupied areas of Donbas "is important", since the expiry of the previous law was "a matter of concern" to all.

Peskov has reiterated Russia's commitment to Minsk-2, saying that Moscow continues to regard these agreements as a non-alternative foundation based on which it is possible to try to move toward "the terms of the settlement."
