The big difference between the American attitude and the Chinese attitude towards ecology is this :

The Americans loudly refuse to do anything, loudly deny that there's a problem, and loudly proclaim their hatred of ecology.

The Chinese say yes to everything but they have absolutely no intention of actually doing anything, they just lie.

According to Climate Action Tracker, https://climateactiontracker.org/countries/china/current-pol...

> This means that according to our assessment, China will meet its 2020 pledge and its NDC targets, but still be above current emissions levels. China’s chief climate negotiator, Xie Zhenhua, has expressed the opinion that China could meet its 2030 peaking targets early, reflecting the conclusions of other studies (Green and Stern, 2017; Xu, Stanway and Daly, 2018; Gallagher et al., 2019b; Wang et al., 2019). CAT analysis confirms that, based on current GDP projections, China is indeed likely to meet the carbon intensity target of its 2030 pledge early.

So the TL;DR is China is likely to meet its pledges but the pledges themselves are pretty weak — rated “highly insufficient” and only consistent with a 4 degrees warming limit.

That’s inconsistent with your “say yes to everything but ... just lie” assessment. It appears they don’t say yes to everything (hence the weak pledge) but will hit the promised target.

Your links don’t support your point either. The first link doesn’t pinpoint the cause (could be a lapse in enforcement) and the second link is about a revision in official figures; Guardian’s reporting is based on a NYT article with a more neutral tone, but even the Guardian article with its loaded title (surprise surprise) didn’t call it lying.

The leaders of america do that, at least half the people in the country want to do something. And the leader of the us will eventually change and we'll get a new goal. Then we'll be like china though because the republicans/oil industry will sue to block changes.

From result standpoint, it's small difference, not a big one.

The Paris Agreement is just a piece of paper. If we go by the "initiative" measure of GGP, the leadership of most countries doesn't display a sufficient amount of it.
