The “Shield of the Americas” summit, organized in Florida in March 2026 by United States (U.S.) President Donald Trump and bringing together leaders from Latin America, carries geopolitical implications that extend far beyond a meeting focused solely on regional security issues. The summit took place immediately after the U.S. military strikes against Iran and emerged as an important diplomatic move demonstrating that the Washington administration is simultaneously projecting power across different strategic arenas on a global scale. Although the official agenda of the meeting was announced as combating drug cartels operating in Latin America and strengthening regional security cooperation, it is evident that a clear objective behind the summit was to limit China’s growing economic and political influence in Latin America.[i]
The initiative known as the “Shield of the Americas” was designed as a security cooperation platform bringing together leaders or representatives from approximately a dozen countries in Latin America and the Caribbean. The main objective of this initiative has been articulated as conducting a coordinated struggle against transnational criminal organizations, particularly drug cartels. Statements made during the summit emphasized the need to adopt stricter security strategies based on intelligence sharing, joint operations, and, when necessary, the use of military force among participating countries. The U.S. administration evaluates this approach not merely as an issue of combating organized crime, but also within the broader context of national and border security. The Trump administration has argued that cartels constitute a direct security threat to the United States due to their involvement in drug trafficking and human smuggling and has openly stated that military tools may be used in response.[ii]
The discourse expressed at the summit indicates that the United States is increasingly adopting a harsher and more security-oriented approach in its Latin America policy. U.S. Secretary of Defense Pete Hegseth’s call for Latin American countries to employ more aggressive military methods against cartels demonstrates that Washington is moving toward a new strategy in which military instruments take precedence over the traditional law-enforcement approach in the fight against organized crime.[iii] This approach points to a line reminiscent of the security-oriented intervention policies that the United States pursued in Latin America during the Cold War period.
Another significant dimension of the summit is that it coincides with a period in which ideological and political transformations in Latin America intersect with U.S. foreign policy. Among the leaders attending the summit were right-leaning figures such as Argentine President Javier Milei, Chile’s newly elected President José Antonio Kast, and Salvadoran President Nayib Bukele. This situation indicates that the recent rightward shift observed in certain parts of Latin America overlaps with Washington’s efforts to reshape its political partnerships in the region.
The absence of countries such as Brazil, Mexico, and Colombia—among the largest economies in Latin America—from the summit reveals the fragmented nature of regional politics. This situation demonstrates that Latin America does not act as a single geopolitical bloc and that different states pursue different foreign policy orientations. In particular, the economic relations developed by some countries with China have emerged as a significant factor limiting Washington’s influence in the region.
China’s growing economic presence in Latin America is considered one of the main motivations behind the United States’ new diplomatic and security initiatives toward the region. In recent years, China’s trade volume with Latin America has increased rapidly, and for many countries China has become one of their most important trading partners. China has also expanded its economic presence in the region through infrastructure investments, port projects, and credit programs. These developments are perceived by the Washington administration as a strategic challenge.[iv]
For this reason, the U.S. administration aims to limit China’s influence in the region by strengthening its security and diplomatic relations with Latin America. The rhetoric articulated by the Trump administration reflects an updated version of the traditional U.S. strategic thinking that advocates protecting the Western Hemisphere from the influence of external powers. Some analysts suggest that this approach can be interpreted as a modern version of the Monroe Doctrine.
From the perspective of Latin American countries, great power competition presents both opportunities and risks. Many countries continue to cooperate with the United States in the field of security while simultaneously expanding their economic relations with China. This situation indicates that the countries of the region have adopted a pragmatic foreign policy approach aimed at balancing between major powers. While China’s infrastructure investments and financing opportunities create significant economic opportunities for many Latin American countries, security and trade relations with the United States remain critically important for regional stability.
In conclusion, the summit of Latin American leaders held in Florida was not merely a security initiative aimed at combating organized crime; it also emerged as a reflection of global power competition in the Western Hemisphere. The competition between the United States’ efforts to establish a security-centered alliance network in Latin America and China’s strategy to expand its economic influence has become one of the fundamental dynamics shaping the geopolitical future of the region. These developments demonstrate that an increasingly visible period of multilayered competition is emerging in global politics, in which military power, economic influence, and diplomatic alliances are used as complementary instruments.
