Sibur, Russia's largest gas processing and petrochemical company, is also looking to benefit from a push eastwards, having partnered with Gazprom to build a gas chemical complex near the Chinese border along the 'Power of Siberia' pipeline. Dmitry Konov, the chief executive of Sibur, told CNBC on Wednesday that the firm sees opportunities from China, particularly in light of Gazprom's pipeline to the Chinese border. "(In the case of) Gazprom, which signed a long-term gas supply contract with China, they are developing two new fields, building the pipeline and building the gas processing plant, at the Russian side of the Russia-Chinese border which allows some supply of our feedstock, our petro-chemical feedstock."
