Trump Admin Slams Sanctions on Cuba Nickel Operation, Disrupting China’s Supply Chains

The Trump administration is turning up the heat on Cuba’s military-controlled economy by targeting a crucial nickel mining operation with new sanctions that could send shockwaves through global supply chains tied to China.

Secretary of State Marco Rubio announced sanctions on Moa Nickel SA on Thursday. This joint venture between Canadian company Sherritt International and Cuba’s state-owned General Nickel Company is a linchpin in the production of nickel, a critical mineral used in electric vehicle batteries and other high-tech applications. By hitting Moa Nickel, the administration aims to choke off revenue streams to Havana’s military apparatus under the guise of national security.

In response, Sherritt International swiftly suspended its direct involvement in joint-venture activities in Cuba and began repatriating expatriate staff from the island. The company also urged its partners in Canada to pull their personnel out. Three Sherritt directors, including chairman Brian Imrie, resigned immediately, underscoring the turmoil sparked by Washington’s clampdown.

Sherritt revealed that sanctions imposed earlier in May had already “materially altered” its ability to operate normally in Cuba. Beyond Moa Nickel, Sherritt holds a one-third stake in Energas, which supplies roughly 10 percent of Cuba’s electricity generation, highlighting the broad reach of U.S. pressure.

These sanctions stem from President Donald Trump’s Executive Order 14404, issued May 1, which authorizes blocking assets of foreign entities operating in sectors deemed vital to Cuba’s economy—energy, mining, finance, and defense—or supporting the Cuban government materially or technologically.

This latest move is more than just a squeeze on Cuba; it’s a strategic strike with global ramifications. Nickel is essential for the lithium-ion batteries powering the electric vehicle revolution, and China dominates much of the battery supply chain. By disrupting Cuban nickel production, the Trump administration is injecting uncertainty into the supply lines crucial to China’s industrial ambitions and the global green energy transition.

The White House’s aggressive use of sanctions to undermine Cuba’s military-linked economy fits a broader pattern of authoritarian overreach. Instead of diplomatic engagement or multilateral pressure, the administration opts for unilateral economic warfare that risks collateral damage to global markets and civilian livelihoods.

As the Trump administration weaponizes sanctions with little regard for broader consequences, the fallout from this move will be felt far beyond Havana’s shores. The nickel mine sanction is a stark reminder that authoritarian tactics in foreign policy come at a cost—one borne not just by targeted regimes but by global industries and democratic accountability alike.
