IOC President Thomas Bach

Chinese tennis star tells Olympic officials she is safe

In a statement, the IOC said its President Thomas Bach had spoken to Ms Peng for 30 minutes.

"[She] was doing fine, which was our main concern," the statement read.

Ms Peng, 35, disappeared from the public eye for almost three weeks after she made sexual assault allegations against a senior Chinese minister.

Her absence triggered widespread concern, with international sports stars and governments calling on China to provide proof that she was safe.
