Well, TikTok might have tried to export the censorship policies of China to other countries. Reportedly, documents show the company guidelines which instruct their moderators to censor content that mentions topics such as the 1989 massacre in 'Tiananmen Square' event.
TikTok's Censorship
Tiktok lists that massacre together with other political "incidents" in the past, such as the horrible Cambodian genocide and the 1998 Indonesia riots. They will not allow those topics to broach on the platform. Here is an example; there are the guidelines on the list of world leaders which the users cannot mention.
