USAID was a tool of imperialism, not charity. The food "aid" it gave was specifically to underdevelop food production in the global south to force reliance on the US Empire, which expropriates vast sums of wealth through imperialism. China doesn't participate in imperialism nor unequal exchange, and as such countries that trade with China and join BRI actually develop, rather than remain underdeveloped and overexploited by the west.
