ANKARA: (Reuters)–Turkey has suspended talks with Gaz de France over a pipeline project that would bring Caspian natural gas to Europe in reaction to a French bill on the Armenian Genocide rule, senior Turkish energy officials told Reuters on Thursday. Nabucco is a 4.6-billion euro ($6.14 billion) project to transport natural gas from Turkey to Austria, passing through Bulgaria, Romania and Hungary. The planned pipeline would reduce Europe’s dependency on Russian gas. France angered Ankara last year when its national assembly passed a bill making it a crime to deny that the mass killings of Armenia’s during the fall of the Ottoman Empire amounted to genocide. "We will suspend partnership by Gaz de France until the French presidential elections. We will decide according to policies to be followed after the elections," a senior energy ministry official, who declined to be named, said. Energy Minister Hilmi Guler declined to comment on the issue of Gaz de France. "We attach great importance to the Nabucco project. We realised the first phase of this project. Turkey is in an important position in meeting Europe’s gas need and we are aware of this," Guler told Reuters. Gaz de France had no immediate comment. The four other countries involved in the project, Bulgaria, Romania, Austria and Hungary, have already approved partnership with Gaz de France in the project, which will transmit Caspian and Iranian gas to Western Europe, bypasing Russia. Austrian oil and gas group OMV heads the consortium planning to build the pipeline. Bulgargaz, Transgaz from Romania, MOL of Hungary and and Turkey’s Botas are also partners in the project. "I am not aware of any talk suspension. Anyway, Gaz de France’s offer is valid by the end of the year," said Dimitar Gogov, Bulgargaz executive director. The consortium has been seeking a sixth partner for a while. Finalising a deal to start building the pipeline has already run into trouble after negotiations with France’s Total for a stake collapsed earlier this year. A senior OMV executive said last month a final investment decision had been further delayed well into 2008 as negotiations to win a sixth investor dragged on. The project has also been criticised for taking too long to plan with no reliable timetable existing for gas suppliers. It faces a series of hurdles, including financing, possible steel bottlenecks and pending European Union permits for the pipeline. If construction of the 3,300 km (2,050 mile) pipeline starts in 2008, it could begin operating in 2011. It could transport annually 25.5 to 31 billion cubic metres of Caspian gas to Europe by 2020. The Turkish armed forces froze bilateral ties with its NATO ally France due to the National Assembly bill. The bill still has to be approved by the Senate to become law.
