"A dangerous situation has developed around the Joint Control and Coordination Centre (JCCC). Ukraine, in particular, President Poroshenko, who spearheaded the creation of such a centre in 2014, is now doing everything to create an unbearable environment for the Russian officers and making unacceptable requirements on them with an eye towards shutting down the centre. The responsibility for this will, of course, lie with the Ukrainian authorities," Lavrov said.

The primary task of the JCCC is to monitor compliance with the Minsk agreements. It consists of representatives of the Ukrainian and Russian sides, as well as the so-called "DPR" and "LPR" (self-proclaimed Donetsk and Luhansk People's Republics).
