Javier Milei's government on Wednesday announced the signing of a letter of intent with the United States for joint patrolling of the South Atlantic over the next five years, in a military cooperation agreement that ratifies Buenos Aires's strategic alignment with the Donald Trump administration and that has triggered alarms over Argentine sovereignty in its maritime spaces. The agreement, signed by the US Southern Command and Argentine Navy authorities, involves the supply of US technology to modernize the South American country's naval equipment and, at the same time, authorizes the participation of US forces in patrolling the Argentine southern sea.

The government of Javier Milei proceeded on Tuesday to open the economic bids submitted by the two international consortia competing for the 25-year concession of the Paraná-Paraguay waterway, Argentina's main fluvial trade artery, despite a warning from the Public Prosecutor's Office about the existence of serious and obvious irregularities that could give rise to criminal and administrative consequences. The Peronist opposition has filed a bill in Congress demanding the immediate suspension of the process.

Bolivian President Rodrigo Paz on Friday thanked his Argentine counterpart, Javier Milei, for sending two C-130 Hercules military aircraft to reinforce the airlift aimed at supplying food and basic goods to the cities of La Paz and El Alto, affected by ten consecutive days of road blockades by peasant unions from the highlands. The regional gesture comes during one of the most critical weeks of the centrist leader's six-month tenure, against a backdrop of shortages and growing political tension with sectors aligned with former president Evo Morales.

Argentina's public universities are staging the fourth Federal University March on Tuesday against the budget adjustment imposed by Javier Milei's government, with the main rally in Plaza de Mayo and simultaneous mobilizations in the country's major cities, while the national administration announced it will meet with rectors after the protest to discuss the allocation of funds for university hospitals. The day combines a strike with suspended classes, a broad opposition turnout, and an official discursive shift aimed at opening a dialogue channel without yielding on the substance of the dispute.

The government of Javier Milei amended Argentina's 2026 budget on Monday with a cut of nearly 2.5 trillion pesos (around 1.79 billion dollars at the parallel exchange rate) —equivalent to approximately 1.6% of the total— in an administrative decision that deepens the adjustment effort to sustain the fiscal surplus target agreed with the International Monetary Fund. The measure, signed by Chief of Staff Manuel Adorni and Economy Minister Luis Caputo, comes one day before the fourth Federal University March, called for Tuesday with its main event in Plaza de Mayo.

The tender to concession Argentina's Paraná-Paraguay waterway for 25 years —the country's main fluvial artery, through which roughly 85% of foreign trade is shipped— has entered its final stretch with two Belgian finalists, Jan de Nul and DEME, and mounting political questions over the tender's design, the local partners involved, and the integrity of the supporting technical documentation.

An Argentine court on Friday lifted the precautionary injunction that had suspended 82 of the 218 articles of the labor reform pushed by President Javier Milei, restoring the full force of one of the most contested laws in the libertarian program.

Argentine senator and former Security Minister Patricia Bullrich said in Santiago on Tuesday that Javier Milei's government maintains the firm determination to locate Chilean former guerrilla Galvarino Sergio Apablaza, on the run since April 1 in Argentine territory, in order to extradite him to Chile. If he is in Argentina, we are going to find him. That is the commitment of the Argentine president, it is the commitment of the government, Bullrich told local media during her visit to the Andean country, where she will meet with Chilean President José Antonio Kast.

Argentine Cabinet Chief Manuel Adorni refused to resign on Wednesday during his first management report before the Chamber of Deputies, in a seven-hour session marked by allegations of alleged illicit enrichment against him and by the unprecedented presence of President Javier Milei in the chamber's gallery, alongside his sister and Secretary General of the Presidency Karina Milei, and the entire cabinet. I committed no crime and I will prove it in court, Adorni told the plenary, on a day the ruling party sought to turn into a political show of support and that the opposition transformed into a parallel trial.

The Falklands sovereignty dispute returned to the centre of the diplomatic agenda this week with two developments of immediate impact: comments by Argentine Vice President Victoria Villarruel demanding that islanders “go back to England” if they “feel English” — despite the fact that in the 2013 referendum islanders voted by a 99.8% majority to remain British — and a disclosure published by The Telegraph that the United States had pressured the British government to tolerate the delivery to Argentina of F-16 fighter jets sourced from allied territory.
