A decision on filling the Odessa-Brody oil pipeline with Kazakh oil cannot be made without Russia's consent, Kazakh President Nursultan Nazarbayev said. "As regards Odessa-Brody, it is necessary to reach an agreement with Russian oil transportation organizations in order to achieve the necessary volume," Nazarbayev said at a joint press conference with Ukrainian President Viktor Yushchenko in Astana on Thursday.
