Don't Say We Weren't Warned

China is attempting to throw their weight around a little farther from their borders than usual:

China's ambassador to Canada warned in remarks published on Saturday against allowing domestic politics to drive the Canadian government's decision on whether to approve Chinese state-owned oil company CNOOC Ltd's proposed $15.1 billion takeover of Canadian oil producer Nexen Inc.

Canada better look out. Who knows whether Nexen will be China's next "core interest."
