Removing barriers to trade in electricity has been a feature of the work of the Energy Charter, and the Energy Charter Secretariat organised on 16 May 2006 a roundtable meeting on cooperation, which aimed to analyse the costs and benefits of greater interconnection and discussed the instruments that could be needed to foster increased cross-border trade. The discussion was based on a series of regional examples from Southeast Europe, the Caucasus and from Central Asia, and served as guidance for the Energy Charter's further work in this area. The draft Programme of Work for 2007 foresees a concentration for the future on encouraging regional trade in the Caspian region, based on approaches that have proved successful in other areas.
