From his CV, published by the Council of the European Union last week, it can be seen that he has served twice in Moscow, the last time from 1999-2002 as the Head of the Press and Information office, and that from 2007 until now he has been the German ambassador in Beirut/Lebanon.
Javier Solana, the European Union's High Representative for the Common Foreign and Security Policy, is quoted:
"Hansjörg Haber will have a crucial role in putting together and launching the mission as a key part of the EU's efforts to address the crisis in Georgia and enhance stability in the region. His range of skills and experience in diplomacy and crisis management will be assets for the mission. He has my full trust and support and I look forward to working with him."Haber told the media yesterday that most of his team is expected to come during this week.
The final mission will start on 01 October 2008 and will involve between 200 and 350 observers. For more details you can read the fact sheet published by the EU Council.
