Even IOC calls the Peng Shuai situation ‘humanitarian matters’ that they would proceed with “quiet diplomacy” [1]. Short of calling this a hostage situation, this is definitely not normal.

IOC is the only entity outside China which contacted Peng Shuai, whose external communication is under heavy control by China, so it may be harder for others to see what is going on.

Also, WTA is calling for an investigation into a #MeToo, which arguably falls under human rights.
