They're saying no to a Chinese puppet org (the UN) using clean environment as an attack on them while China does nothing to address their environmental impact.
That's a strong and outright ludicrous statement. The UN's highest body, the Security Council, has 5 permanent security members with veto powers, which includes the UK and US ( alongside China, Russia, France). So China doesn't have any more power over the UN compared to the US.
> using clean environment as an attack on them while China does nothing to address their environmental impact.
China is adressing their environmental impact - most notably in electricity generation where they're replacing coal power plants.
They probably have more coal plants than anyone else in the world too.
Citing raw numbers is pointless when China is involved since everything is so numerous there.
At least it proves that this statement is untrue.
The whole point of this article is that two not China counties are flexing that veto authority and won't hesitate to use it to stop this measure.
