The Women's Tennis Association (WTA) says Peng Shuai's latest interview about her sexual assault allegations "does not alleviate" its concerns.
Peng accused a Chinese government leader in November in a social media post but it was swiftly deleted and the player then disappeared for weeks.
But the 36-year-old said on Monday she never alleged sexual assault.
"Her recent in-person interview does not alleviate any of our concerns about her initial post," the WTA said.
The organisation's CEO and chairman Steve Simon added: "To reiterate our view, Peng took a bold step in publicly coming forth with the accusation that she was sexually assaulted by a senior Chinese government leader.
