SINA Announces Issuance Of New Rules On Microblogging By The Beijing Municipal Government

SHANGHAI, Dec. 16, 2011 /PRNewswire-Asia/ -- SINA Corporation (NASDAQ GS: SINA), a leading online media company and mobile value-added service ("MVAS") provider serving China and the global Chinese communities, today announced that the Beijing Municipal Government issued new rules on microblogging.

On December 16, 2011, the Beijing Municipal Government issued the Rules on the Administration of Microblog Development, or the Rules, which became effective on the same date.  The Rules, among other things, require users of microblogging services to register their identities with microblogging service providers.  Microblogging service providers are required to verify the identities of their users.  These procedures will be carried out at the backend, which would not affect the account name of microblogging users, and will not apply to "read-only" users.  The Rules identify eleven categories of content that are restricted from being disseminated.  Microblogging service providers are required to implement systems and procedures to ensure the security of user information and that the information disseminated by microblogging users is in compliance with the content restriction policy.  The Rules are applicable to microblogging service providers within the Beijing Municipality and their users.  Existing service providers must within three months of the issuance of the Rules report on the procedures taken to comply with the Rules.

SINA's management is currently closely monitoring this new regulatory development and evaluating the impact the Rules may have on its Weibo.com microblogging operations.
