Softbank, Japan's leading search engine company, has a 34% stake in Alibaba. It also persuaded Alibaba's founder Jack Ma to start e-commerce site Taobao. Softbank will start a service in 2010 which connects Taobao to its Tahoo portal in Japan. Softbank owns a 35% stake in Oak Pacific Interactive which owns the popular social networking and game playing sites RenRen and Kaixin.com. Softbank's strategy in China is to concentrate on e-commerce, local social networking sites and online games. This avoids hitting a wall of government censorship which has hampered progres in China for Google and a number of other sites. Other steps taken by Softbank's founder are to work with respected local partners. Jack Ma sits on Softbank's board and Son sits on Alibaba's board. Softbank sees its mobile business connected to internet growth because mobile users are increasingly using the internet, and Softbank is a mobile carrier.
