U.S. Sanctions Target Cuba’s Military Conglomerate GAESA and Nickel Joint Venture
5/10/2026, 9:12:00 PM
Background & Context
The Trump administration has intensified economic pressure on Havana since January 2026, halting oil shipments from Venezuela and expanding a fuel blockade that UN experts label “energy starvation.” The blockade has contributed to nationwide blackouts, water shortages and a projected 6.5-7.2 % contraction of Cuba’s GDP in 2026. On May 1, President Donald Trump signed an executive order broadening U.S. authority to sanction foreign firms and banks that support Cuba’s security apparatus or engage in corruption.
Core Event: Sanctions Announced
On Thursday, May 7, 2026, U.S. Secretary of State Marco Rubio announced a new sanctions package targeting three entities: the military-run conglomerate Grupo de Administración Empresarial S.A. (GAESA), its executive president Brigadier General Ania Guillermina Lastres Morera, and Moa Nickel S.A. (MNSA), a joint venture between Canadian miner Sherritt International and Cuba’s state-owned La Compañía General de Níquel. Under the executive order, U.S. persons are prohibited from dealing with the designated entities and any assets they hold in the United States are frozen.
Key Entities
- GAESA – Controls roughly 40 % of Cuba’s economy, spanning tourism, finance, retail, logistics and foreign exchange.
- Ania Guillermina Lastres Morera – Executive president of GAESA, responsible for managing its overseas assets.
- Moa Nickel S.A. – Operates nickel and cobalt mines in Holguín; supplies feed material expected to last until mid-June.
- Sherritt International Corp. – Canadian mining company that announced an immediate suspension of its direct participation in Cuban joint-venture activities and began repatriating expatriate staff.
- Cuban leadership – President Miguel Díaz-Canel and Foreign Minister Bruno Rodríguez Parrilla, who denounced the measures as unlawful aggression.
Data & Statistics
- GAESA’s assets are estimated at $18-20 billion, with revenues “likely more than three times the state’s budget.”
- The conglomerate accounts for ?40 % of Cuba’s GDP.
- Moa Nickel’s operations provide a critical source of hard-currency; its feedstock is projected to sustain production through mid-June.
- Since January, the United States has intercepted at least seven oil tankers, cutting Cuba’s fuel imports by 80-90 %.
Official Statements & Responses
- U.S. State Department (Rubio): Described GAESA as “the heart of Cuba’s kleptocratic communist system” and said the sanctions aim to “deprive the regime of illicit assets.”
- Cuban Foreign Ministry: Called the sanctions “an act of ruthless economic aggression” that violates international law.
- President Díaz-Canel: Characterized the measures as “unilateral aggression” and “pernicious interference from American imperialism.”
- Sherritt International: Stated it had “suspended its direct participation in joint-venture activities in Cuba, effective immediately,” and was repatriating staff.
Criticism & Opposition
UN special experts warned that the fuel blockade amounts to “energy starvation” with grave human-rights implications. Cuban officials argue the sanctions constitute “collective punishment” that harms civilians more than the regime. Independent analysts caution that further isolation could deter foreign investment, deepening the humanitarian crisis.
Conflicting Reports & Gaps
- GAESA’s asset valuation varies between $18 billion (Miami Herald) and $20 billion (U.S. State Department).
- Revenue multiples are described as “three times the state budget” and “likely more than three times,” without independent verification.
- The precise impact on Moa Nickel’s output beyond the mid-June feed-stock estimate remains unconfirmed.

What’s Next
Rubio warned that “additional designations can be expected in the coming days and weeks.” A June 5 deadline has been set for foreign banks and companies to cease dealings with GAESA under secondary sanctions. A State Department delegation visited Cuba in April for talks on humanitarian relief, and further diplomatic negotiations may hinge on Cuba’s response to the economic pressure.
