Is anyone in this field able to recommend their own or others' research into the topic of how Brazil's economic dependence on other countries (including the United States, China, and Russia) affects its current/previous foreign policy? So far I've learnt that Brazil is highly dependant on commodities, that the U.S. remains its largest contributor of FDI, trade and imports to China and US largely revolve around agriculture, and that imports of Russian gas into Brazil have soared recently. I've managed to research Brazil's foreign policy more generally, under Lula.
For context, I'm an IR student at the University of Exeter, currently producing a case study into topic for a module titled 'international politics of the global south'. I'd therefore much appreciate recommendations to sources that approach this issue in some way, from a political lens, or any other advice you may have to offer.
Thank you very much!
