Russia is betting big on China just like it did on Europe. Last year (2017)l, Gazprom supplied close to 200bn cubic metres of gas to Europe, equivalent to almost 40 per cent of the continent’s needs, and the source of the vast majority of the company’s profit. Oil and gas production accounts for 40 per cent of the country’s fiscal budget.
The Chinese demand will probably float the Russia economy and restore the Russian Ruble. There is not Ruble ETF to play that trade. This will probably deminish China need to import any middle-east oil and drastically impact the dollar game.
