Rubio Sanctions GAESA and Moa Nickel Under May 1 Cuba Order
11 articles · Updated · Responsible Statecraft · May 15
GAESA, its director Ania Guilermina Lastres Morera, and Moa Nickel SA were hit with new U.S. sanctions, the first designations under a May 1 order targeting foreign activity in Cuba’s energy, mining, finance, defense and security sectors.
Sherritt International — Moa Nickel’s Canadian-Cuban co-owner and a major Cuban gas and mining investor — said its top leadership resigned and the company and employees would begin leaving Cuba after more than 30 years.
Four weeks is the wind-down period the administration gave foreign firms to end transactions with GAESA-linked entities before U.S. assets can be blocked, putting hotel operators, banks and energy companies on alert.
Rubio said more designations are coming as Washington pairs tighter sanctions with a disputed $100 million aid offer tied to prisoner releases and broader political opening, while Havana denies such a proposal was made.
25 U.S. surveillance flights since February and a stalled 270,000-barrel diesel shipment underscore a broader deadlock: the Trump administration says it still prefers diplomacy, but is escalating pressure on Cuba’s foreign partners.

U.S. Sanctions and Sherritt’s Withdrawal Push Cuba Toward Economic Collapse: Humanitarian and Geopolitical Fallout in 2026
Overview
The report examines how decades of U.S. sanctions, recently intensified, have deepened Cuba’s economic crisis and strained U.S.-Cuba relations. Cuban officials blame these sanctions for the country’s economic and social hardships, while the U.S. maintains pressure to prompt change. The Cuban economy remains tightly controlled by the military-run conglomerate GAESA, limiting reforms and transparency. The withdrawal of major foreign investor Sherritt International, following new sanctions, is expected to worsen energy shortages and reduce export revenues. These developments have heightened humanitarian challenges, fueled mass migration, and increased calls for systemic change both inside Cuba and among the diaspora.
