Disputes between Moscow and Kiev reemerged last week amid Gazprom’s disruption of gas supplies to Ukraine, Kiev’s ban on Russian planes flyovers, and a recent explosion of power lines on Russian-annexed Crimea, Reuters reported.

The energy conflict over gas pricing in Ukraine has launched an EU wide debate invoked by a statement issued by Gazprom’s Chief Executive, Alexei Miller warning against possible gas disruptions to Europe, if Kiev pursues its intentions to join a free trade alliance with the EU on January 1, 2016.

Gazprom is seeking a meeting with the EU’s antitrust chief to settle the issues on 15 December, Bloomberg informed.
