A simple question has gripped the sports world and drawn the attention of the White House, United Nations and others:
Where is Peng Shuai?
The Chinese tennis star disappeared from public view for weeks in November after she accused a top Chinese leader of sexual assault, prompting a global chorus of concern for her safety. Then, the editor of a Communist Party-controlled newspaper posted video clips that appear to show Ms. Peng eating at a restaurant and attending a tennis event in Beijing. Days later, the International Olympic Committee said its president had spoken with her in a video call.
