An official with Russia’s Natural Gas Export Company said on April 4 in Moscow that his country will sign a governmental agreement late this year to kick off exports of natural gas to China, after a momerandum of understanding signed off by President Putin during his visit to China earlier this year.
Russia will export 60-80 billion cubic meters of natural gas a year to China through two pipelines, the company official said. According to the MOU signed by Putin, the first pipeline will be put in use by 2011 and cost $10 billion to build.
