As it was informed by "Market Leader (US)"
Europe is afraid of Russian investments: what are the reasons?
The world media report that the  European Commission didn’t let Gazprom buy 50% share of Central European  Gas Hub (GmbH) - CEGH.  This is one of Europe’s most important natural  gas hubs. 80% of it belongs to Gas&Power GmbH OMV (Austria), the  remaining 20% belongs to Wiener Borse AG.  In terms of trading volume,  CEGH buys/sells about 2Bcf of gas a month, 80% of which is of Russian  origin. The mentioned marketplace satisfies the demand of Australia and  other European countries.
