The responsibility of the US government is to its residents, not just its citizens. These includes being an attractive location for foreign visitors with money and labor to spend in US.
And also to be member of the world community.
Finally many Chinese people with friends in China are citizens.
'A member of the world community' in the same way that China is 'a member of the world community'?
Let's be clear: the Chinese government is going to cause its citizens great pain because it performs this information manipulation with its own technology. It is at fault if other countries take steps to protect the world from the CCP's actions, not the nations taking those steps. Don't victim-blame either the other countries or the Chinese people, both of who are harmed by the CCP's actions.
Same way that Iraqi was freed from Saddam, it's all his governments fault for having weapons of mass destruction.
Speaking of information manipulation, just because people have the freedom to access all information, doesn't mean they won't be manipulated, you're seeing this happen in front of your very eyes.
At least in China people know they're not seeing the full story from the media. They know they can't access certain website because of censorship. In the US people just swallow whatever that they happen to see and believe, the results are comical.
In many ways, Chinese people are less manipulated than certain set of people in America. There were genuine anger when Li Wenliang died. But then eventually they realized that shits so much worse elsewhere - meanwhile in the US people still believe that disease China is worse because - manipulation? Or inability to overcome cognitive dissonance.
You do realize that China and the US are held to different standards because of different stated goals.
If we want to uphold freedom and be a part of the world community then yes, we in fact cannot sink to the same tactics and policies as the Chinese government.
Actually this is a well understood principle, and is in fact why our police cannot use criminal tactics to catch criminals (at least on paper).
How much would you recommend importing Chinese censorship before it outweighs the benefits you're suggesting here? I'm not saying there's no valid trade-off there, but catering to the needs you're describing does have a cost.
Apparently, China is having no problem attracting foreign investment while conducting every kind of human rights abuse that exists including genocide. So, not sure, your point stands in practice.
