Moscow is watching with concern Ukraine resolutely and consistently repudiating its own regions.

The Kremlin says that Ukraine is ruining its own territorial integrity with a blockade of rebel regions in the east.

Russian President Vladimir Putin’s spokesman Dmitry Peskov said Friday that Moscow is watching with concern Ukraine “resolutely and consistently repudiating its own regions, condemning millions to living without social security, banking, medical and legal services.” He wouldn’t say if Moscow could consider incorporating the regions into Russia, like it did with Ukraine’s Crimean Peninsula in March 2014.

Ukrainian President Petro Poroshenko declared the transport blockade of rebel-held areas Wednesday, saying it will be in place until the separatists return the region’s industrial assets to Ukrainian jurisdiction. The move represented a U—turn by Poroshenko, who had previously tried to end a blockade on the rebel east imposed by nationalist groups.
