Chinese e-commerce firm Alibaba Group acquired an 18 percent stake in Web portal Sina Corp's micro-blogging service Weibo in its first big move into selling advertising on China's social networks. The $586 million deal, which values Weibo at more than $3 billion, will provide more advertising revenue to Weibo as Sina tries to monetize the service and increase its lead over rival Tencent Holdings' social messaging product, WeChat.

JuzishuijingChenzhong: For Alibaba, the move could benefit its ecological system building, the layout of social e-commerce and its publicity. For Sina, the $3.2 billion valuation is a recognition of its value and boosted its investors' confidence, both at home and abroad.
