I mean, the Do Nothing Win meme might be popular, but I suspect China is doing a bit more than nothing right now, that or all those Chinese companies producing Shahed clones are just selling them to consumers to fly as RC planes.
China has always been doing shitloads just not making a fuss about it.
Them high speed rail lines don't magically appear out of nowhere
Them rare earth extraction/refinement technology don't magically appear out of nowhere.
Them 055, electromagnetic catapults and J-36/50s don't magically appear out of nowhere.
etc, etc you get the idea.
Saying China do nothing and win is misinterpretation at best and outright hubris at worst. China do shit loads but if by do nothing you mean they work to get themselves in a position where they don't have to roll with pigs in da mud to look busy, then yes I guess China is doing nothing.
