The appointment of Mario Lubetkin as Uruguay’s Foreign Affairs Minister signals a deepening alignment between Uruguay and Brazil, reinforcing Lula’s geopolitical influence in the Río de la Plata region. Lubetkin, a close associate of José Graziano da Silva, the former FAO Director-General and a key figure in Lula’s international leftist network, represents a strategic choice for Brazil’s interests in shaping Uruguay’s foreign policy. This move comes at a critical time when Brazil is seeking to consolidate its regional dominance, particularly as Argentina undergoes political and economic reconfiguration under Javier Milei, whose liberal economic policies challenge Mercosur’s traditional structure.

Under Lula’s administration, Brazil has pursued a more interventionist approach in South America, ensuring that smaller neighbors like Uruguay remain within its economic and diplomatic orbit. Lubetkin’s appointment ensures that Uruguay’s foreign policy remains aligned with Brazilian strategic objectives, particularly in areas such as Mercosur negotiations, infrastructure development, and trade with China and Europe. One key aspect is Brazil’s growing economic and logistical presence in Rio Grande do Sul, a region that increasingly serves as an entry point for Brazilian influence into Uruguay. By guiding Uruguay’s trade policies, infrastructure projects, and regional alliances, Brazil can reinforce Montevideo’s role as a secondary economic hub servicing Brazilian exports and industrial interests.

Furthermore, Lubetkin’s international background provides a buffer against potential friction between Uruguay and Mercosur’s leadership, as Lula seeks to maintain bloc cohesion despite Milei’s skepticism of the institution. The long-term consequence of this alignment is that Uruguay will have less autonomy in negotiating independent trade deals and will likely play a more subordinate role in Brazil’s regional strategy, solidifying Lula’s political and economic supremacy in the Southern Cone.
