(VOVworld) – The Vietnam National Oil and Gas Group and its Russian partner Gazprom signed an oil exploitation pact in the framework of the 19^th St. Petersburg International Economic Forum held in Russia from June 18-20. The two sides agreed on a number of basic conditions to develop the Nagumanovsky and North Purpovsk oil fields in Russia, which their joint venture, Gazpromviet, has been permitted by local authorities to exploit. PetroVietnam President Nguyen Quoc Khanh led a Vietnamese delegation in talks with leaders from Russia’s major oil and gas groups to strengthen bilateral cooperation. Khanh and Gazprom Chairman Alexey Miller also discussed further affiliation between the two groups, including cooperation in the expansion of the Dung Quat Oil Refinery and Vietnam’s liquefied natural gas supply. The PetroVietnam delegation held talks with the state-run Russian oil company Rosneft to foster their current collaboration.
