KIEV, Ukraine, Jan. 7 (UPI) -- Ukrainian energy company Naftogaz said it filed an official complaint in Europe, arguing Russian gas pipeline expansion plans would limit competition.
Russian energy company Gazprom in September signed a shareholder agreement on the development of the second phase of the twin Nord Stream pipeline system with his counterparts at German energy companies BASF and E.ON, as well as those from French company ENGIE, Austria's OMV and Royal Dutch Shell.
