If it doesn't care then why does it send its climate envoy like every month to speak with China then.As if US care about "CN sincerity".
For someone who says it doesn't care, it sure seems like it cares a lot.
Anyway, China is the one which doesn't really care. If the US wants cooperation then drop the confrontational rhetoric otherwise the US can go pound sand.
China has a responsibility towards its citizens' well-being. That means that energy supply must increase a lot and the best and most stable source of such energy is coal.
If the West truly wants China to move its net-zero emissions goal from 2060 to 2050 then it should get ready to send money to China.
$200 Billion per year should be enough for China to move its goal to 2050
