The Chengdu Institute of Biological Products (CDIBP), part of the China National Biotec Corporation, was established in 1958 and is one of the largest research and manufacturing bases for biological products in China. The institute’s facilities are located in a garden-like setting in the city of Chengdu and occupy over 480,000 square meters. There are over 1,400 employees in the institute, 54% of which are scientific and technical personnel. In 2001, the concerned central government departments granted approval for CDIBP to effectively buy shares of the Chengdu Rongsheng Pharmaceuticals Co., Ltd. with its blood product production line to become the principal shareholder of Rongsheng.
