Tennis: Chinese star Peng Shuai says she is 'safe, well' in video call with International Olympic Games boss

Chinese tennis star Peng Shuai has had a video call with the International Olympic Committee president, assuring him she is safe and well.

Photos and videos of Peng at a Beijing tournament had done little to dampen international concerns, after she alleged a former senior Chinese official sexually assaulted her and then went missing for three weeks.

The IOC says Peng thanked president Thomas Bach for his concern about her well-being during a 30-minute call.

"She explained that she is safe and well, living at her home in Beijing, but would like to have her privacy respected at this time," the IOC says.

"That is why she prefers to spend her time with friends and family right now. Nevertheless, she will continue to be involved in tennis, the sport she loves so much."

French foreign minister Jean-Yves Le Drian had called on the Chinese authorities to provide more reassurance, echoing a statement by the Women's Tennis Association that the images were "insufficient" proof.

"I'm expecting only one thing - that she speaks," Le Drian told LCI television, adding that there could be unspecified diplomatic consequences, if China did not clear up the situation.

The United States and Britain had also called for China to provide proof of Peng's whereabouts.

Current and former tennis players, including Naomi Osaka, Serena Williams and Billie Jean King, also called for confirmation she was safe, using the social media hashtag #WhereIsPengShuai?

The concern over Peng came as global rights groups and others have called for a boycott of the Beijing Winter Olympics in February over China's human rights record.

On November 2, Peng posted on Chinese social media that former Vice Premier Zhang Gaoli had sexually assaulted her several years ago.

Neither Zhang nor the Chinese Government have commented on her allegation. Peng's social media post was quickly deleted and the topic has been blocked from discussion on China's heavily censored internet.

Hu Xijin, editor-in-chief of the state-backed Global Times, posted a 25-second video on Twitter that showed her smiling, waving and autographing giant tennis balls for children at the Fila Kids Junior Tennis Challenger Finals tournament.

The Global Times is published by the People's Daily, the official newspaper of China's ruling Communist Party.

The tennis event's official WeChat page shows photos of her at the tournament. Peng, 35, was the world No.1 doubles player in 2014 - the first Chinese player to achieve a top ranking - after winning the doubles titles at Wimbledon in 2013 and the French Open in 2014.

On Sunday, Peng visited a popular restaurant in downtown Beijing, according to a video posted by Hu and confirmed by the restaurant manager to Reuters.

Seven people, including Peng, were at the Sichuanese restaurant, said manager Zhou Hongmei, adding that they ate in a private room and were joined by the restaurant's owner.

"It was crowded at the restaurant as usual," Zhou said, showing a bill that included noodles and bamboo shoots. "They didn't have much, I think they mostly chatted."

The Women's Tennis Association (WTA), which has threatened to pull tournaments out of China, says the photos and video were "insufficient", and did not address the WTA's concerns.

The International Tennis Federation (ITF) says it will continue to seek confirmation from Peng that she is safe.

Chinese state media outlet CGTN released what it claimed Peng had sent to the WTA's chairman denying she was sexually assaulted.

Chairman Steve Simon said he had a hard time believing that Peng herself had written the email.
