Sanctions Overview
On early May 2026, U.S. Secretary of State Marco Rubio announced sanctions that placed the military-controlled Grupo de Administración Empresarial S.A. (GAESA) and its president Brigadier General Ania Guillermina Lastres Morera on the Treasury’s Specially Designated Nationals list. It also targeted Moa Nickel S.A., the joint venture of Sherritt International and Cuba’s General Nickel Company. The sanctions follow a January 2026 oil embargo on Cuba’s main supplier Venezuela and a May 1 2026 executive order expanding sanctions over Cuba’s energy, defense, metals, mining, finance and transport sectors.
Key Figures & Stakes
GAESA, controlling at least 40 % of Cuba’s economy, is led by Ania Guillermina Lastres Morera. Moa Nickel S.A., a 50 % Sherritt, 50 % Cuban venture, supplies about 10 % of the island’s electricity through Energas. Sherritt International announced immediate suspension of its Cuban activities and the resignation of three directors.
Data & Impact
GAESA holds $18–$20 billion in assets, with revenues over three times the state budget. Sherritt’s shares fell 42 % to $0.145 after the sanctions. Moa’s feedstock is expected to last until mid-June, and the loss could deepen the power-grid collapse that left 11 million Cubans without electricity in March. The measures also target a nickel-cobalt supply chain used in China-linked batteries.
Official Statements
The State Department said the sanctions are “designed to disrupt financial flows benefiting Cuba’s leadership rather than its population” and aim “to bring about a positive change in behavior.” The White House called the order a tool to “counter Cuba’s malign influence” and protect U.S. security. Cuban Ambassador Ernesto Soberón Guzmán called them “collective punishment,” and Foreign Minister Bruno Rodríguez called them “genocidal.”
Criticism & Opposition
Cuban officials argue the sanctions punish ordinary citizens while targeting “military-linked companies” that the regime uses to preserve political control, and they claim the U.S. approach ignores the humanitarian crisis worsened by the embargo and oil blockade.
Conflicting Reports
GAESA asset estimates range from $18 billion (Miami Herald investigation) to $20 billion (U.S. State Department). Sherritt has not been formally designated under the executive order, but warned that designation could occur at any time.
