Fair enough if we're going just on pledges on total emissions change by 2030 than China and many other countries like India, Sweden, Denmark and Morocco are in line for the pledges taken. This is just a component of the Paris Accords the main pledge was to take action to limit warming well under 2 degrees. No countries action or policies are in line to meet that pledge. That can be seen in the article you linked showing how far off all four emitters are to 1.5.

Climate action tracker and the CCPI they put out are the best sources for accurately tracking countries actions. China and pretty much all other countries fall down on their net zero targets rooted in fiction and missing NDC targets.
