China. To date, Teva has only very limited operations in China. Tevas principal product sold in China during 2007 was Interferon Alpha 2B, used in the treatment of hepatitis and certain types of cancer, which is manufactured by Hualida, a local company controlled by Teva. Over the next few years, Teva plans to register and bring to market in China additional products from Tevas oncology portfolio.
