A shadow of the Monroe Doctrine is lengthening across the Americas, but this time it’s called the “Donroe Doctrine.” President Trump is enacting a bold strategy to reclaim U.S. influence, driven by a growing concern over China’s expanding reach in what has long been considered America’s sphere of influence.
The core of this shift lies in the 2026 National Defense Strategy, which prioritizes securing the Western Hemisphere. This isn’t simply about combating drug trafficking or terrorism; it’s a direct response to Beijing’s increasing economic and political power in Latin America, now viewed as a critical national security issue.
This strategy isn’t merely a revival of old ideas. It’s a modernization, a “Trump Corollary” to the Monroe Doctrine, explicitly stating the U.S. will act unilaterally to prevent nations like China, Russia, and Iran from establishing strategic footholds in the region. The entire hemisphere, from the Arctic to the southern tip of South America, is now considered a vital defensive perimeter for the U.S. mainland.
The historical context is crucial. The original Monroe Doctrine of 1823 warned European powers to stay out of the Americas. Later, the Roosevelt Corollary asserted the U.S. right to intervene as a regional police force. Now, President Trump is reviving this assertive posture, fueled by China’s growing presence.
This isn’t just about military might. The strategy reclassifies drug cartels as “narco-terrorists,” allowing for the deployment of military assets previously reserved for conventional warfare. Drone strikes and expanded operations are already underway, targeting cartel networks and actors in countries like Venezuela.
China’s economic investments – port ownership, control of logistics hubs near the Panama Canal – are no longer seen as neutral commerce. They are viewed as potential military and strategic threats. The administration aims to counter this through “transactional diplomacy” and “denial defense,” preventing any adversary from gaining decisive leverage in the region.
Beijing, however, has its own ambitions. A recent Chinese policy paper outlines a plan to build a “China–LAC community with a shared future,” revealing a primary objective that is decidedly political, not merely economic. This signals a comprehensive, security-oriented push into the Western Hemisphere.
China’s goals extend beyond trade and infrastructure. They include securing support for Beijing’s claims on Taiwan and reshaping the regional order to marginalize U.S. influence. Economic pressure and diplomatic retaliation are already being used to enforce compliance from Latin American nations.
The scope of China’s investment is vast, encompassing infrastructure, energy, ports, telecommunications, space cooperation, and high-tech sectors like AI and semiconductors. Much of this infrastructure has dual-use capabilities, blurring the lines between civilian and military applications.
Security cooperation is also escalating. China is expanding military, law enforcement, and intelligence collaboration with Latin American governments, exporting its internal security model and embedding its influence within regional systems. This is presented as benign cooperation, but it’s a clear attempt to position China as an alternative security partner to the United States.
The U.S. is responding with concrete steps: blocking Chinese control of strategic assets, applying tariffs and sanctions, and working to remove regimes seen as aligned with Beijing. Increased naval and troop activity signals a firm commitment to maintaining U.S. security dominance in the region.
While China doesn’t operate under a formal doctrine, its Belt and Road Initiative has made it a dominant economic force, becoming the top trading partner for much of South America. It offers an alternative to U.S. conditions, appealing to leaders frustrated with traditional American policies.
Many Latin American countries are attempting a delicate balancing act, seeking economic benefits from China while maintaining security ties with the U.S. This has intensified the geopolitical clash between the two superpowers.
Despite remaining the largest foreign investor, U.S. private firms often struggle to compete with China’s state-backed enterprises on large-scale projects. The U.S. is attempting to expand development financing, but matching China’s scale and speed remains a challenge.
China is actively reassuring regional partners, portraying itself as a cooperative, development-focused actor, signaling flexibility while reaffirming its commitment to the region. This carefully crafted image aims to counter U.S. pressure.
A significant ideological shift is also underway in Latin America, with right-leaning leaders gaining power in several countries. This trend raises the possibility of increased support for U.S. efforts to limit Chinese influence, potentially reshaping the geopolitical landscape.
