SINA Corporation (Nasdaq:SINA), a leading online media company and value-added information service provider for China and for global Chinese communities, announced today that it has formed a strategic alliance with Bandai Networks, a subsidiary of the third largest toy company in the world, Bandai Co. Ltd., to provide digital character content to mobile phones in China. Established as a subsidiary of Bandai Co. Ltd. in September of 2000, Bandai Networks builds on its parent company's strength in character merchandising along with its own expertise in server management and applications to operate a wide variety of mobile phone and Internet content services. Some of the most popular properties and brands of Bandai Groups include the Power Rangers, Gundam, Digimon, Strawberry Shortcake and Hello Kitty product lines. To date, Bandai Networks boasts 4 million fee-based users to its domestic pay mobile phone services in Japan. It has the largest number of subscribers as a Mobile Contents Provider at present.

The first project of the venture will begin on May 30, 2003, providing digital character images and content to mobile phones using the SMS (Short Messaging Service) system. SINA will offer server operation and customer service while Bandai Networks will provide for content planning and development. China's Short Messaging Service (SMS) usage, brought about by the rapid adoption of mobile phones, has experienced rapid growth in the past two years with volume growing from 16 billion messages sent in 2001 to 95 billion messages sent in 2002 and is expected to reach 200 billion in 2003.

"This represent an important strategic alliance for SINA's wireless business," says CEO of SINA, Wang Yan.
