Chinese state-owned energy companies have been unfairly targeted in Canada by regulations on investment from foreign government-controlled companies, according to China’s top diplomat in the Canadian oil patch.  The critique comes amid a steep drop in new investment in Canadian energy assets by Chinese state-owned enterprises. That has raised questions about China’s commitment to increasing its presence in Canada’s oil and gas industry, which requires foreign capital to fund development.  “Discriminating against SOEs from China is not very wise. For commercial deals, the companies are making their own decisions” instead of taking orders from Beijing, Chinese Consul General Wang Xinping told The Wall Street Journal in an interview.
