Closer Look: Uncertainty Clouds China-Russia Natural Gas Deal

(Beijing) -- Chinese President Hu Jintao ended his visit to Russia on June 21, but he failed to put the finishing touches on a deal to pump natural gas from Siberia to China over the next 30 years.

The two countries remain divided on natural gas prices.

According to a 2009 framework agreement between China National Petroleum Corp., the country's largest oil and gas supplier, and its Russian counterpart OAO Gazprom, two pipelines will transport a combined 68 billion cubic meters a year over a 30-year period.
