For example, we withdrew our observers from the Joint Centre for Control and Coordination (JCCC) in the 'LPR' and 'DPR' [the acronyms for the 'Luhansk People's Republic' and 'Donetsk People's Republic'], but if you want us to return them, let's agree on the distribution of observers along the contact line only.' This is a kind of blackmail. The West sees and understands this very well, and it knows that Putin's resources are very limited. The West and Ukraine have already faced such actions by Putin many times to understand what they imply. One shouldn't pay too much attention to that," Oreshkin said.
