For the first time, a thorough review of official records allows for the mapping of Cuba's military expansion in Angola, especially in Healthcare, Education, Oil, Construction and Mining. Although the provision of services represents its main source of income, the Cuban government also manages public limited companies, including private clinics, and exports medicines and blood products to the African nation, which generate multimillion-dollar profits.

For decades, claims of modern slavery have tainted Cuba's international mission in Angola without a single official document to prove it…until now. Based on more than 7 300 payrolls and account statements issued by the Cuban Military — among other official documents, testimonies, and reports — this two-part investigation reveals Cuba's multimillion-dollar business network that profits from its workers abroad in the name of solidarity.
