In December 2007, the Energy Charter Conference reaffirmed its support for the finalisation of negotiations and adoption of the Energy Charter Protocol on Transit to expand the existing provisions of the treaty. This work proceeded until October 2011, when the European Union argued that, given current developments in the international energy situation and the lack of progress in negotiations and consultations, it appeared no longer opportune to continue talks. A review of the issue at the end of 2015 noted the continued demand for a multilateral legally-binding framework for energy transit, and recommended further exploring the basis for negotiations of such an agreement, which could address various aspects of oil, gas and electricity transportation and transit.
