Shield of the Americas
An Anti-Cartel Bloc That Split the Map

← Back to Latin America News

On March 7, President Trump gathered leaders and senior officials from Latin America and the Caribbean at his golf resort in Doral, Florida. There he launched a multilateral anti-cartel alliance named the "Shield of the Americas." Trump put the count at 17 countries, among them Argentina's Milei, El Salvador's Bukele and Paraguay's Peña. The stated aims were dismantling drug cartels and curbing illegal migration. The real aim is geopolitical: to counter China.

Who came, and who did not

What defined this summit was less the guests than the empty chairs. Brazil, Mexico and Colombia, together more than half the region's population, all stayed home. Lula's Brazil is wary of multilateral security frameworks. Sheinbaum's Mexico wants to keep its relationship with Washington in bilateral channels. Colombia's Petro was never going to join, given his politics.

A "pledge against cartel criminal activity," signed by every delegation present, touches on intelligence sharing and coordinated arrests and asset seizures. Written into it is the deliberately vague possibility of "kinetic operations." The actual institutional design has not been published. How far the bloc will work is still unknown.

The real target is China

The meeting kept stressing the need to counter "hostile foreign influence in the Western Hemisphere, especially China." China's trade with Latin America and the Caribbean hit a record 518 billion dollars in 2024, and some estimates put it above 700 billion by 2035. Its rising footprint through infrastructure, undersea cables and port operations looks to Washington like a security threat. In February, under US pressure, Panama revoked a CK Hutchison affiliate's canal port concession. That sits on the same line.

Colombia holds the key

The bloc's structural weakness is the absence of Brazil and Mexico, but another variable is Colombia's June 21 runoff. If the right-wing De la Espriella wins, membership turns realistic. Add the region's third-largest population, and the framework bites differently. If Cepeda wins instead, Petro's line continues and South America leans further from Washington. Research groups including the Stimson Center see it plainly: a bloc missing its biggest members falls short of any real "reordering of the region."

Who signed barely matters. Brazil and Mexico did not come. That one fact shows how far this framework reaches and where it stops.
