Would it work that way? A non-trivial portion of the emissions of those countries are caused by manufacturing products that are exported to the US and Europe
I think we overestimate how much is proxy emissions even now. Those are whole modern growing societies not just factories for us. Our view of climate change and carbon emission tends to be, like other things, very Euro-and-US centric and provincial.
What I’m saying is that if you turned us off you’d only delay the oncoming train, not stop it.
