Ukraine gas dispute with Russia raises supply fear

Even through the break-up of the Soviet Union and crises that followed, Russia’s gas exports to Europe, 80 per cent of which transit Ukraine, have always been reliable.

But unless Ukraine agrees to pay much more for the gas it takes from the pipeline for its own use – Moscow first asked for roughly a four-fold increase, but now suggests it should be more than five-fold – Russia has said it will cut out Ukraine’s portion from the gas going into the pipe.
