# Argentina-US dam safety pact > Live situation record from CLSTR: https://clstr.news/situations/argentina-us-dam-safety-pact > Updated: 2026-08-04T19:30:33.000Z. Sources: 6. Developments: 2. In March 2024 the administration of President Javier Milei signed a confidential Memorandum of Understanding with the United States Army Corps of Engineers. The agreement gave the U.S. agency authority to draft and update safety regulations for Argentine dams and to take part in planning, construction, maintenance and research of hydraulic infrastructure. The pact was kept secret from Congress and the public, with clauses classifying all related data as non‑disclosable. Its existence was later revealed by journalist Sebastián Premici after a public‑information request and confirmed by former U.S. ambassador Marc Stanley. In early August 2026 Milei issued a decree of necessity and urgency authorising the Brazilian Navy to conduct the annual FRATERNO XXXIX joint exercise in Argentine territorial waters. The drills, scheduled for mid‑August, aim to enhance combined naval, air‑naval and amphibious training and signal Argentina’s commitment to regional security. The same announcement reiterated the secret dam‑safety memorandum, underscoring ongoing concerns about Argentine water and energy sovereignty amid deeper security cooperation with Brazil and the United States. ## Timeline ### 2026-08-04: Argentina greenlights Brazilian naval drills and secret US dam pact under President Milei Argentina approved Brazilian naval drills in its waters and a secret US agreement giving the US Army Corps of Engineers authority over Argentine dam regulation. 3 sources. https://clstr.news/cluster/argentina-greenlights-brazilian-naval-drills-and-secret-us-dam-pact-under-president-milei ### 2026-08-02: Argentina secretly signs water resources memorandum with US Army Corps Argentina's government secretly signed a March 2024 memorandum with the US Army Corps of Engineers granting U.S. influence over dam safety regulations and water resources, revealed by a public‑information query 3 sources. https://clstr.news/cluster/argentina-secretly-signs-water-resources-memorandum-with-us-army-corps --- Cite as: Argentina-US dam safety pact.
