Presidents of Hungary, Austria, Romania and Bulgaria urged Azerbaijan to support the Nabucco West project in a letter to Azerbaijani President Ilham Aliyev, Austrian President Hans Fischer said.
Slovakia hosted the Central European Summit last week.
The consortium developing Shah Deniz will decide the fate of the project in late June, choosing a route to deliver gas to Europe. The choice is between Nabucco West and TAP.
Fischer prefers Nabucco West because it would provide more energy resources and diversify gas supplies of the Central and Eastern Europe, regions dependent on Russian gas.
Turkey shares the views of the Eastern European presidents in this aspect.
