A video claiming to show Chinese player Peng Shuai out with friends is "insufficient" evidence of her safety, says Women's Tennis Association chief Steve Simon.
On Saturday, Chinese state-affiliated media posted two clips on Twitter of Peng purportedly having dinner with her coach and friends in a restaurant.
"While it is positive to see her, it remains unclear if she is free and able to make decisions and take actions on her own, without coercion or external interference," said Simon.
Peng, 35, has not been in direct contact with the WTA since making sexual assault allegations against a former China vice-premier two weeks ago.
