The women’s tennis tour has suspended all tournaments in China over safety concerns of Peng Shuai.

The Chinese Grand Slam doubles champion accused a former high-ranking government official in that country of sexual assault. She dropped out of public view after raising the allegations in an early November social media post that was quickly taken down by Chinese authorities.

WTA Chairman and CEO Steve Simon issues a statement that reads in part: “Unfortunately, the leadership in China has not addressed this very serious issue in any credible way, and while we now know where Peng is, I have serious doubts that she is free, safe, and not subject to censorship, coercion, and intimidation.”
