Happily, today the problems are reversed. Expertise is now required in the field of safe and environment-friendly disposal of chemical weapons and cleaning up of contaminated sites all around the world, but not least in the ex-Soviet-led countries. The participants and speakers to the NATO-Russia advanced research workshop on the "Ecological Risks Associated with the Destruction of nd th Chemical Weapons", hosted by the University of Lüneburg on 22 - 26 October, 2003, therefore, came from many different parts of the world. Of the eight countries represented at the workshop, two were ex-Eastern- Block, and six were Western countries. Yet the West was by no means overrepresented. On the contrary, the Russian expert-speaker contingent, with 33 participants, did justice to the size of their country - and to their chemical-weapons problem - and provided the majority of active participants. In all, there were 57 participants, of which 11 dispatched from the TACIS project "The development of the chemical weapons" facility at the detached plant No 4 of OAO Khimprom, Novocheboksarsk.
