Canadian Prime Minister Stephen Harper is preparing for a crucial state visit this week to China where, among other things, he is expected to discuss selling Canadian oil products to the Asian giant. Harper is anxious to construct a Pacific oil pipeline after President Barack Obama rejected the building of a route from Alberta to Texas by TransCanada's Keystone XL, largely on environmental and safety concerns. A spokesman for Harper told the Associated Press that it is "absolutely in Canada's interests" to build a new pipeline to transport oil to China.
