This chapter analyses Brazil’s role as a regional geopolitical actor, highlighting the characteristics and significance of its governance in foreign relations. Brazil’s relationship with African states in the South Atlantic holds strategic importance. This relationship is facilitated through regional organisations such as the Union of South American Nations (UNASUR) and the South Atlantic Peace and Cooperation Zone (ZOPACAS), and is further enhanced by Brazil’s membership in the Community of Portuguese Language Countries (CPLP) and BRICS (Brazil, Russia, India, China, and South Africa). These affiliations position Brazil as a key contributor to security, stability, and multilateral cooperation in the region. We argue that Brazil is poised to become a significant power capable of ensuring a safe and secure environment in the South Atlantic, particularly in the Gulf of Guinea, thereby contributing to the region’s security and stability while safeguarding its national interests.
