The introduction of amendments to the Constitution of Ukraine to grant a special status to certain areas of Donetsk and Luhansk regions, under demand of the Russian envoys in Trilateral Contact Group, is fundamentally unacceptable, Ukrainian Foreign Minister Pavlo Klimkin said.

"They now will endlessly play with the topic of a special status and how it should be assigned. And that thing that a special status should be for a year or more isn't a problem itself – they want to write some things into the Constitution. And as for me in principle it is unacceptable from the point of view of the logic of the process," Klimkin said in his interview with Den newspaper (Day) published on Friday.

"Of course, they will play with this topic. They aren't interested in Donbas, they're interested in shaking of the situation in the country [Ukraine]. And they will further do that," the minister added.

When asked about expectations of Germany's Chairmanship of OSCE, namely, if the German side could succeed with '57-1' formula (denial of access to the peace solution of the conflict of the party involved in Donbas aggression), the minister said that "as a consensus it would be difficult, but we're ready to talk on this topic, in particular as a part of the coordination of some parameters of strengthening of the OSCE mission."

"In reality, adoption of '57-1' formula would be a precedent since it might greatly change OSCE. Of course, it would be on our hand. I have a good attitude towards the capability of German to promote OSCE, but in general I'm skeptical towards the idea to change the principles of this international security organization, which is based on the consensus taking of the decisions," Klimkin stressed.
