> why should they bother to change anything until China improves it's own power production either?
That one is easy: because the USA (and Europe) have been the ones who pumped nearly all of the carbon that's screwing us up now for the last 100 years or so. If you take the accumulated amount of carbon emissions, I am sure you'll arrive at the conclusion that China must not be blamed for the current crisis (you can only accuse China of not helping solve the mess caused by others - which is valid but something else altogether).
Not to mention that, on a per-capita basis which is what matters when you want to blame people for using too much carbon, China is still much lower than the USA... in fact the USA is off the charts per-capita compared to even the most modern other economies.
