Peng Shuai: Tennis Australia criticised for ban on t-shirts supporting Chinese player

Tennis Australia has been criticised by former and current stars for banning t-shirts supporting absent Chinese player Peng Shuai.

Spectators attending the tournament in Melbourne have been blocked from publically displaying their support for Peng.

Viral videos have shown security officials and police requesting one supporter to remove a t-shirt that featured an image of the Chinese player and the words “Where is Peng Shuai?”

Peng has since reappeared, but the Women's Tennis Association (WTA) has refused to play any tournaments in China this year.

Tennis Australia is the latest to face backlash for its stance on the matter, with Martina Navratilova and Nicholas Mahut among the critics.

"I think it's really cowardly," she added in an interview on the Tennis Channel. "This is not a political statement, this is a human rights statement."

Seeded men's doubles player Mahut meanwhile drew attention to Chinese alcohol brand Luzhou Laojiao, one of the sponsors of the tournament venue, Melbourne Park.

"What’s going on!? What lack of courage!," Mahut said on Twitter. "What if you did not have Chinese sponsors? Beyond disappointed."

A GoFundMe page seeking support to distribute Peng Shuai shirts at the Australian Open had raised thousands of dollars within 24 hours over the weekend.

Tennis Australia initially stated that t-shirts featuring the words "Where is Peng Shuai" broke their rules on "political" statements.

The authority later responded to the
