South America

BLUF

South America is a theater of intensifying geopolitical competition among the Estados Unidos, China, and, to a lesser degree, Rússia, with regional actors — Brazil, Argentina, and Venezuela — operating as pivots or points of friction. The region simultaneously confronts a governance crisis driven by transnational organized crime, deepening economic dependence on China through the BRI, and a cycle of democratic instability that serves as a vector for external influence. It is not a theater of conventional conflict, but it is an active space for hybrid warfare, cognitive operations, and competition over critical infrastructure.


Regional Strategic Dynamics

China–U.S. Competition

China has become the largest trading partner for most South American countries, surpassing the United States across most of the region’s economies. Infrastructure investment through the BRI (ports, railways, energy, Huawei 5G) creates structural dependencies that translate economic power into political influence. Critical examples:

  • Ports: Chancay (Peru, COSCO Shipping) — the largest deep-water port on the South Pacific, with potential military and intelligence uses
  • 5G: Deployment of Huawei infrastructure in Brazil, Argentina, and Chile — creating potential access to sovereign communications data
  • Energy: Lithium-mining contracts (Argentina, Chile, Bolivia — the “Lithium Triangle”) and renewable-energy investments

Transnational Organized Crime as a Hybrid Threat

Brazilian criminal organizations (PCC, CV) and Colombian/Mexican cartels operate as proto-states in territories of weak governance, monopolizing violence, informal taxation, and social services. Their cognitive capacity — narrative control within communities and systemic corruption of institutions — makes them relevant actors in any analysis of regional hybrid threats.

Democratic Instability

The 2019–2026 cycle saw coup attempts or constitutional ruptures in Bolivia, Peru, Brazil, and Venezuela. These events serve as vectors for intervention by external actors and as tests of the institutional resilience of the region’s democracies.

Active Hybrid Threats

  • Algorithmic disinformation: Russian and Venezuelan influence networks amplifying anti-democratic and anti-U.S. narratives
  • Money laundering and cryptocurrency: Venezuela and PCC networks used to circumvent Iranian and Russian sanctions
  • Huawei infrastructure: Potential Chinese intelligence access to sovereign communications across multiple countries
  • Tri-Border Area (Brazil-Argentina-Paraguay): Documented hub for Hezbollah financial operations and organized crime
