Djokovic supports WTA China suspension

Unconvinced by Peng's public appearances since a scandal broke a month ago over her sexual assault accusations against Chinese former Vice-Premier Zhang Gaoli, the WTA said it wanted assurances of her well-being and has sought an investigation.

Djokovic, who recently co-founded a players' union aiming to represent both male and female professionals, said: "I support fully WTA's stance because we don't have enough information about Shuai Peng and her well-being," the Serbian said after a Davis Cup tie in Madrid.

The WTA drew criticism from China for its decision which comes as Beijing prepares to host the Winter Olympics in February. Global rights groups and others have called for a boycott of the Beijing Olympics over China's human rights record.
