Yes I read the parent comment, do you mean the two questions

  > Is it proposing to ban US citizens from reading research papers written by Chinese citizens?

  > Or from publishing research in places that might be read by them? 
  

Clearly, both are impossible to implement, wouldn't you agree? The bill talks about "AI products," as per the article, and that would be what a consumer uses, not what a researcher uses. Can legislators ban the reading of papers in America? There are 1st amendment issues there. But for protection against external states messing with our population, there's a different set of rules.
