Moscow - Russian gas export monopoly Gazprom said Friday that its dispute with Ukraine over payments could cause disruptions in deliveries to Western Europe, a news agency reported.
Gazprom spokesman Sergei Kupriyanov said that Gazprom head Alexei Miller had notified Europe's largest clients that it could not rule out the possibility of a cut off, according to Itar-Tass.
At issue is the lack of progress in reaching agreement with Ukraine's Naftogaz over 2 billion dollars in non-payments for imports by Kiev, with a New Year's deadline looming with threatened cut-offs by Gazprom.
Gazprom supplies about one-quarter of the European Union's gas needs, 80 per cent of which is shipped through Ukraine.
