> China consistently weights 25-30-% worse than #2 in each table
I agree with your larger point, but I'm not sure this is entirely accurate. If you look at table 4 on p. 32 (i.e. printed page number; PDF page number is 21, and the complete data can be found at the end of the PDF, starting on (printed page number) p. 110), you'll see that the scores are derived from three indicators: (i) the prevalence of IUU (Illegal, unreported, and unregulated) fishing, (ii) each country's vulnerability to IUU fishing, and (iii) their response to it. Only in the Prevalence table for 2021 does China "weight 25-30% worse" than #2 (South Korea). In the Vulnerability table, China's score is only marginally worse (3.3-5%) than Japan, the second-worst in both 2019 and 2021. In the Response table, China (3.31) is not even among the top 10 worst countries, scoring comparably to Israel (3.29) and better than Singapore (3.87) and UAE (3.82).
Also worth noting: the Prevalence score is calculated based on the number of vessels recorded on IUU lists (see p.12), so we'd expect countries with a larger number of fishing vessells to score higher (i.e. worse) in respect of Prevalence, which is why even the US made it to #8 worst in the Prevalence table for 2021.
