(CPIC) agreed to collaborate on a slew of aluminum and energy projects with a potential investment of about $7.5 billion over the coming years. The Memorandum of Understanding between the two companies was signed in the presence of US Secretary of Energy Steven Chu, Chinese Minister of Science and Technology Wan Gang, during the US visit of the Chinese President Hu Jintao.
