Russia is not ready to assume obligations regarding control over Ukrainian-Russian border and ensure the presence of OSCE observers, Ukrainian Foreign Minister Pavlo Klimkin announced.

I understand that Russia is not ready to assume the full level of obligations on the presence of OSCE observers and the effective control of the Ukrainian-Russian border. It is not ready to acknowledge the facts of permanent border crossing by machinery and mercenaries and the intervention of the armed forces from Russian territory. These were the main moments of our conversation," he said at a briefing in Kyiv on Monday.

He also said that members of quadrilateral talks in Berlin had refused to make declarations and promised to focus on negotiations.

"We agreed that we would not work on a declaration or any statements. Rather, we will focus on the essence of the matter immediately in the course of our talks," Klimkin said.

Foreign ministers of Ukraine, Russia, Germany and France met in Berlin August 17 to discuss the settlement of the situation in Ukraine.
