Yintao Yu said Communist Party members accessed data on US users as well as protesters in Hong Kong.
Hong Kong is a semi-autonomous region in China with its own government.
Some American lawmakers have expressed concern that TikTok's ties to ByteDance means the data it holds is subject to Chinese law.
It was also available in Hong Kong until TikTok pulled out of the market in 2020 following the imposition of a sweeping national security law.
Anyone who tries to open TikTok from within Hong Kong will see a message that reads "We regret to inform you that we have discontinued operating TikTok in Hong Kong."
