Germany's RWE might become the sixth partner in the Nabucco natural gas pipeline, which aims to transport Caspian basin gas to Central Europe, Turkish Energy Minister Hilmi Guler said. «We are considering having RWE as the sixth partner in Nabucco,» the minister told CNN Turk TV in an interview. Guler also said Iraq's natural gas could be transported to European markets via Turkey. The 5 billion euro ($7.4 billion) Nabucco project - designed to pass via Turkey and the Balkans to Austria - has been delayed but is a key plank of the European Union's plans to reduce its dependence on Russian gas imports.
