Women's tennis stars have called for more information on Chinese player Peng Shuai's wellbeing.
There has been concern over Peng's safety since November, when she posted allegations online of sexual assault against a former senior politician. She subsequently denied making the claim.
Victoria Azarenka says there has not been "much development" in the case.
"Hopefully we will get to hear from her personally at some point," said the Belarusian.
Speaking after winning her second-round match at the Australian Open, Azarenka - who is on the Women's Tennis Association (WTA) Player Council - said players are making "all efforts to make sure she is safe".
