Peng Shuai: China says tennis star case maliciously hyped up
China has said the controversy surrounding tennis star Peng Shuai has been "maliciously hyped up", in its most direct response to the issue yet.
Ms Peng disappeared from the public eye for almost three weeks after making sexual assault allegations against China's former vice premier, triggering widespread international concern.
She has since re-appeared, but questions remain over her wellbeing.
On Tuesday, China's foreign ministry said it was "not a diplomatic matter".
"I believe you have all seen that she recently attended some public events and had a video call [with the president of the International Olympic Committee]," spokesman Zhao Lijian told reporters.
"I think some people should stop deliberately and maliciously hyping [the issue] up, let alone politicise this issue," he said.
Ms Peng, 35, is one of China's top tennis players. In a 1,600-word post on Chinese social media platform Weibo earlier this month, she said former Vice Premier Zhang Gaoli - who is 75 - had "forced" her to have sexual relations with him.
"Even if it's just striking a stone with a pebble, or a moth attacking a flame and courting self destruction, I will tell the truth about you," she wrote.
It was the first time such an allegation had been made against one of China's senior political leaders. Mr Zhang has not responded to the allegations.
After sharing her post on Weibo, the tennis player was not heard or seen publicly for several weeks. Her safety became a matter of international concern, with prominent players including Serena Williams and Naomi Osaka joining calls from governments and tennis officials demanding to know she was safe.
The outcry prompted Chinese state media to release a series of photographs and videos that appeared to show all was well.
But concerns over Ms Peng's safety and wellbeing remain.
The Women's Tennis Association (WTA) has said the recent videos "don't alleviate or address... concern about her wellbeing and ability to communicate without censorship or coercion".
Human Rights Watch criticised the IOC over the video call, saying its "collaboration" with Chinese authorities on Ms Peng's reappearance "undermines its expressed commitment to human rights, including the rights and safety of athletes".
