> They're saying no to a Chinese puppet org (the UN)
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.
More coal generation too. All this means without context is that they're big. Their commitment to green initiatives has been extremely toothless to date
And they also have the most lax environmental standards. Green energy is nice but allowing business to dump whatever they want into the environment isn't.
I would imagine China will demand a clean environment be a human right and then turn around and say they have no duty to help with it because they have been and always will be a “developing nation”.
