The WTA had received widespread praise for suspending its tournaments in the country after Peng said in a now deleted 2021 social media post that a senior former Chinese government official had sexually assaulted her.
Peng then briefly disappeared from public view and later denied making the accusation, sparking fears for her safety.
“After 16 months of suspended tennis competition in China and sustained efforts at achieving our original requests, the situation has shown no sign of changing,” WTA said in a statement.
