Tennis stars Billie Jean King, Naomi Osaka, and Chris Evert have spoken out about the disappearance of Peng Shuai, one of China’s biggest stars. Peng has not appeared in public since early this month. On November 2, in a post on the Chinese platform Weibo, she accused ex-Vice Premier Zhang Gaoli of sexual assault. Despite having over half a million followers, her Weibo account has been blocked. After China’s state-owned television broadcaster CGTN released an email on November 17 supposedly from Peng, the concerns over her safety have only grown. Watch the video here.
