BEIJING -- Tennis star Naomi Osaka is among those expressing concern about a fellow player who has gone quiet since making a sexual assault allegation against a former top government official in China.
The former No. 1-ranked, four-time major winner from Japan posted on social media on Wednesday to join those asking: Where is Peng Shuai?
Osaka wrote on Twitter that she hoped Peng and her family "are safe and ok."
"I'm in shock of the current situation," she wrote, "and I'm sending love and light her way."
Other leading players, including men's No. 1 Novak Djokovic, and the organizers of the women's and men's professional tennis tours have been calling for a full investigation into the allegations made by the two-time Grand Slam doubles champion.
Peng wrote in a lengthy social media post earlier this month that a former vice premier had forced her to have sex despite repeated refusals. The post was removed from her verified account on Weibo, a leading Chinese social media platform, and China's entirely state-controlled media has suppressed all reporting on the case.
Reports of the allegations circulated overseas for more than a week before WTA chairman and CEO Steve Simon issued a statement Sunday saying, "Peng Shuai, and all women, deserve to be heard, not censored."
"Her accusation about the conduct of a former Chinese leader involving a sexual assault must be treated with the utmost seriousness."
The WTA also said it had received confirmation that Peng is "safe and not under any physical threat," but it has not been able to directly reach her.
The men's tour followed Monday, with ATP chairman Andrea Gaudenzi saying tennis authorities were "deeply concerned by the uncertainty surrounding the immediate safety and whereabouts of WTA player Peng Shuai."
"We are encouraged by the recent assurances received by WTA that she is safe and accounted for and will continue to monitor the situation closely," Gaudenzi said. "Separately, we stand in full support of WTA's call for a full, fair and transparent investigation into allegations of sexual assault against Peng Shuai."
Peng, 35, wrote that Zhang Gaoli, a former vice premier and member of the ruling Communist Party's all-powerful Politburo Standing Committee, had forced her to have sex despite repeated refusals following a round of tennis three years ago. She said Zhang's wife guarded the door during the assault.
Her post also said they had sex once seven years ago and she had feelings for him after that.
As is usual for retired Chinese officials, the 75-year-old Zhang dropped from public sight after his retirement in 2018 and is not known to have any intimate professional or political connections to current leaders.
Peng won 23 tour-level doubles titles, including at Wimbledon in 2013 and the French Open in 2014. She was a semifinalist in singles at the US Open in 2014. Peng hasn't played at the top tier since the Qatar Open in February 2020, before restrictions imposed for the COVID-19 pandemic.
Peng also played in three Olympics -- 2008, 2012 and 2016 -- but the International Olympic Committee has remained silent about her allegations. The IOC and China are organizing the Beijing Winter Olympics starting Feb. 4.
Her accusation was the first against a prominent government official since the #MeToo movement took hold in China in 2018 before being largely tamped down by authorities the same year.
When asked during a daily briefing earlier this week about Peng's allegation, Chinese Foreign Ministry spokesperson Zhao Lijian said: "I have not heard of the matter, and it is not a diplomatic question."
