An interesting side note to the battle over the Keystone pipeline is that China is a major partner in the Canadian oil project, the same Chinese off-shore (outside China) oil company owns one third of Chesapeake Energy, the company that the Sierra Club is partnering with.
So, the Sierra Club made themselves partners with the Chinese that are pushing for the Keystone pipeline.
China is a major partner in the Canadian oil project
There are a lot of Canadian Oil Sand projects. Many developments spread of many, many miles. China is a very minor player overall in the oil sands.

I have no doubt Chinese companies own some shares, but not a third or even a tenth.
