Brussels, 30/01/2004 (Agence Europe) - European Commissioner Pascal Lamy and his Russian counterpart, German Gref, are to begin, on Friday in Brussels, the decisive phase of talks aimed at a bilateral agreement on conditions for Russia's accession to the World Trade Organisation. This phase is also a very tricky one as the most politically sensitive subjects are emerging, but the aim is to try to reach a comprehensive package in due course, it is said in Brussels. The meeting, the first since the EU/Russia Summit in November last and Duma elections in December, focused on: - trade aspects of commitments for opening up the Russian Energy market to foreign competition (prices, etc.), liberalisation of the services market mainly for telecommunications and discriminatory taxes imposed on European air carriers when flying over Siberia.
