On Aug 28, 2020, The Ministry of Commerce and the Ministry of Science and Technology revised the "Catalog of Technologies Prohibited or Restricted from Export".
"Personalized Information Push Service Technology Based on Data Analysis" and "Artificial Intelligence Interactive Interface Technology" were added to the "Restricted Technology" section. This revision may affect the sale of TikTok to any non-Chinese entity, as these two items may involve Tiktok's technology.
