The purpose of BRI is to industrialize countries and build up new customers for the products China makes. They are doing it for their own benefit, sure, but it isn't done in a manner that's exploitative. Compare that to Western Countries, where brutal IMF loans come with requirements to sell off and privatize nationalized industries and resources (commonly oil or rare Earth), and claims of exploitation from China are merely there to protect the validity of the Western IMF loans. After all, why would anyone take a Western loan if the Chinese loans and programs are usually on much better terms? You'll find that the Global South is quite aware of this and is thus turning from the West and towards China.
