you have some valid points but the path to the end goal you envision is not a single one.This position completely ignores the history of the Third World and how it is the west responsibility the state it is in. This is basically going "poor people are poor because they want to" and completely ignore the multitude of factors that go into poor people being and staying poor.
How do we expect the Third World to achieve any of that if whenever they try to gain control of their resources and move forward, they get couped, invaded or rigged and subservient elites put into place every single time since the dawn of the colonial era?.
How exactly are they supposed to succesfully break away from this cycle without the help of other, bigger countries?. Specially smaller countries that don't have the history, resource and cultural depth that its afforded by China size and long history, before you try to bring it up as an example, and even China didn't do it alone, either.
Would have China be able to break away from this cycle without the help of USSR?. Should have Stalin told Mao "is not our responsibility to bail out countries"?
Its hypocritical and delusional to demand such from the Third World, while also expecting to prioritize deaings with China and not expect them to get subverted by Western interests if you don't provide the mechanism nor the efforts for that not to happen.
China goes the BRI way, it captures some domestic business elite, and then that domestic business elite buys off domestic political elite. Soo, China ain't so unconcerned about the global south as you think it is
That means that China may throw 100 baits but if only 10 catch something, thats 10 more than what it had before. You are complaining "what about the rest 90" which is valid, but China isn't some all powerful, all knowing entity. Don't forget it is still a developing country which has multiple internal issues and external issues that it has to resolve first
So based on all that, it is doing a very good and admirable job. Finally don't forget, you can criticise China all you want, but know this:
If China fails, that's it for the global south. Which other entity would be able to mount a similar challenge? That would be centuries and millennia of further Western domination. So, before you chest-thumb and point fingers, think about this. rather do 1 right and 0 wrong than 1000 right and 1 wrong because when you come at the king, you best not make any mistakes or you are dead.
