Turin: The tennis world continues to demand to know the whereabouts and welfare of missing Chinese player Peng Shuai, who disappeared after accusing a former top Chinese official of sexually assaulting her.
On Friday the Women's Tennis Association threatened to pull out of the lucrative Chinese part of its tour unless it is proved that Peng is safe.

WTA chairman Steve Simon told a media outlet: "We cannot stand by compromises. This is a right and wrong issue."
Men's world number one Novak Djokovic backed that stance following his win over Cameron Norrie at the ATP Finals in Turin.
He said: "It's important because this is horrifying. I mean, a person is missing.
"China is a huge country. It's a very important part of the world especially for the WTA. They have many tournaments there. I mean, this is necessary for us to take whatever action.
