Lula and Sheinbaum Forge United Front on Non-Interference and Cuba Embargo

Presidents Luiz Inácio Lula da Silva of Brazil and Claudia Sheinbaum of Mexico used a high-profile videoconference on Wednesday to project a common front against perceived foreign interference, as both nations’ relations with Washington sour under fresh US tariff offensives. In a 40-minute call joined by their foreign ministers, the two leaders “reaffirmed the importance and value they attribute to the strengthening and preservation of multilateralism, international law, democracy and the principle of non-intervention, particularly in the current complex global context,” according to a Brazilian presidency statement. They also issued an unequivocal call for the United States to lift its six-decade-old embargo on Cuba and voiced shared concern over a worsening humanitarian situation on the island.

The demonstration of Latin American leftist solidarity comes at a moment of acute tension. Both Brazil and Mexico have been singled out by the Trump administration’s latest tariff measures, while each has faced accusations—direct or implicit—of foreign meddling in their domestic politics. Lula, speaking separately before the call, drew a pointed parallel between ongoing teacher protests in Mexico and the mass demonstrations that convulsed Brazil in 2013, arguing that those earlier protests were exploited by far-right forces to destabilise then-president Dilma Rousseff and ultimately to impose what he described as a “coup” via impeachment. He suggested “someone’s finger” might be behind the Mexican unrest, “and maybe it’s not even Mexican.” The remark, reported prominently in both Brazilian and Mexican outlets, underscored the conviction in Brasília and Mexico City that external actors are attempting to weaken elected progressive governments.

Beyond the rhetorical alignment, the videoconference yielded concrete steps on the bilateral energy agenda. Lula announced progress toward a formal cooperation instrument between Brazil’s Petrobras and Mexico’s Pemex, covering areas from oil and gas to biofuels. The leaders also agreed to accelerate talks on updating the bilateral legal framework for trade and to deepen collaboration in health, tourism, public governance, science and technology. The energy pact, if finalised, would link the state champions of Latin America’s two largest economies at a time when both are under pressure to reduce dependence on US-dominated supply chains.

From a regional perspective, the joint call to lift the Cuba embargo, while not new, gains diplomatic weight when issued by the region’s two most populous nations in unison. Viewed from Havana, the statement provides a rare moment of high-level backing as the island grapples with severe shortages. Analysts in London note that the Sheinbaum-Lula axis represents a revival of a distinctly Latin American multilateralism that had ebbed during the pandemic and the previous Mexican administration. By coupling the non-interference doctrine with concrete energy integration, they are crafting a defensive posture against Washington’s economic coercion while signalling to their domestic audiences that progressive governments can deliver tangible South-South cooperation. The enduring question is whether the shared rhetoric can withstand the asymmetrical pressures of US power, especially if the Mexican teachers’ movement continues to gather momentum and provide fodder for external critics.
