In order to reduce the target asset-liability ratio efficiently and enhance the company's overall competitiveness, many factories (Alumina, electrolytic aluminum and bauxite) introduce the third-party investors to support them. On one hand, it is predicted that China Aluminum Industry still has more than one million tons of output growth in the next two years. On the other hand, 200%alumina and 50%bauxite self-sufficiency will also make the company’s cost lower than the industry average.
