This case covers TikTok's purchase of Musical.ly and the reaction of the United States government, including the review of the purchase by the Committee on Foreign Investment in the United States (CFIUS) and the reaction of the presidential administration of Donald Trump. The case delves into the mechanics of CFIUS' legal mandate and its review process, in order to shed light on how the United States views data security in the context of rising geopolitical tensions, particularly with China and Russia. The case also looks at how China and Russia, among others, are seeking to establish their own versions of "internet sovereignty" in order to expand their domestic control and international influence. The case asks how these countervailing forces impact a company such as TikTok that seeks to become a global platform and how it can respond.
