The Constitution does not guarantee any rights to the Chinese government.
ByteDance is a Chinese company with it's headquarters in China. The so-called TikTok ban is a call for ByteDance to sell off it's controlling position over TikTok, otherwise TikTok can no longer operate in the US.
The fact that China is spinning this issue as a TikTok ban is telling.
Our government gets to decide the terms under which businesses operate in this country. Always has and always will. This is not a constitutional question.
