Fosun International also owns stakes in U.S.-listed Chindex, a hospital management company focused on China, and Focus Media, an outdoor advertising company.
Fosun, an investment company which owns the other half, has said it had a right to purchase the stake from the two first, in the event they wished to sell.
Shares in Shanghai Fosun Pharmaceutical (Group), a Chinese pharmaceutical manufacturer and distributor controlled by billionaire Guo Guangchang, fell by 1% today after the company said it had received domestic regulatory approval for a secondary stock listing in Hong Kong.
