Inflation is pretty fraught. No one seems to have a good grip on what to do with it. There's multiple ways for every country to measure inflation, most them have to do with the prices of specific categories of goods. How does that work when most of the goods used for an index are price controlled? How do you measure such a thing when prices are driven by both market dynamics and public policy?

Harping on inflation is sort of like saying China should be paying attention to yardage gains on the gridiron while they're busy playing baseball. China is playing a fundamentally different game than the North Atlantic. Part of that game is trapping capitalists by incentivizing them to invest without it being in the capitalists' long term interest. Of course there's going to be a difference between Chinese financial reporting and European - China is trying to undermine the European world order using European money freely given by Europeans (and their settler descendants).

That doesn't mean they are fudging numbers and completely incapable of getting accurate information. It just means their focus is different and they'll only put in the effort they have to in order to attract investment. The rest of their efforts are going towards building and executing 5-year plans that actually contribute to their society and preventing the North Atlantic from infiltrating, invading, starving or nuking them.

But yeah, ok. They could report inflation numbers better. Why don't you go talk to people who moved their businesses to China or invest billions in China and see if they think your complaint matches their reality. Until then, you're literally picking at nits.
