KIEV, Nov. 27 - Ukraine's Energy and Coal Industry Ministry has again requested of the Energy Community Secretariat the immediate initiation of consultations over the South Stream gas pipeline project, which runs counter to Ukraine's national interests, an informed source in the government told Interfax-Ukraine.

"In our view, the situation that has developed puts in doubt the effectiveness of the realization of the Energy Community's main tasks involved in the creation of a unified energy market," the Interfax source quoted part of a ministry letter as saying.
