Chinese biotechnology company 3SBio Inc. said Wednesday that Liping Xu, one of the company's founders, is retiring from its board of directors for health reasons.
3SBio said Xu has been a director of 3SBio and its predecessor, Shenyang Sunshine, since 1993. She is also stepping down as a company vice presdient. Her retirement is effective Wednesday.
She is being replaced by Peiguo Cong, a managing partner of a Beijing law firm since 1994.
Cong will serve as an independent, non-executive director.
