Chinese chase Canadian oil

CHINA’S state oil companies are creating a political furore in the Canadian province of Alberta as they seek to buy their way into the Athabasca oil sands, the world’s largest petroleum resource.
The prospect of Chinese oil companies diverting the bitumen reserves to refineries in the People’s Republic is creating anxiety in Washington and concern in the Alberta government. The high price of crude oil has stimulated billions of dollars of new investment in Alberta’s tar sands which contain more than 1 trillion barrels of oil.
