The Trump administration on 24 June broadened its sanctions campaign against Cuba, designating five entities tied to key sectors of the island's economy along with a member of the Castro family, as part of what Washington described as a sustained effort to cut off revenue streams flowing to the Cuban government.

What the New Sanctions Cover

Secretary of State Marco Rubio announced the measures, stating they targeted entities and individuals that 'fund, facilitate, or benefit from the regime's malign activities, both in Cuba and across our hemisphere.' Three of the five designated entities are linked to Grupo de Administración Empresarial S.A. (GAESA), the military-run conglomerate that Washington describes as the financial backbone of the Cuban state.

'GAESA continues to operate as the financial muscle behind the Cuban regime's repressive security apparatus,' Rubio said.

The Five Designated Entities

ALMACENES UNIVERSALES S.A. (AUSA), a GAESA subsidiary, was sanctioned for its role in storage, transport, and port-related services. According to the State Department, AUSA controls container traffic at Cuba's Mariel Special Development Zone, a major logistics hub that has drawn significant foreign investment.

Also designated were RAFIN S.A., described as a key financial management arm of GAESA, and BANCO FINANCIERO INTERNACIONAL S.A. (BFI), which reportedly handles much of the banking activity involving foreign entities doing business with Cuba. Both operate within Cuba's financial services sector.

Washington additionally targeted GEOMINERA, S.A., a state-owned enterprise managing Cuba's non-nickel mineral assets — including partnerships with foreign investors such as Australian-based Antilles Gold — and EMPRESA SIDERURGICA JOSE MARTI, known as Antillana de Acero, Cuba's largest raw steel producer.

Castro Family Member Designated

In a notable escalation, the administration designated Annalie Lilliam Rueda Cardero, citing her status as an adult family member of Alejandro Castro Espín — the former head of Cuban intelligence services and son of former Cuban leader Raúl Castro. Alejandro Castro Espín himself was sanctioned earlier in June, making this designation part of a widening net around the Castro-linked network.

Warning to Foreign Businesses

The State Department issued a broader warning to foreign companies and financial institutions, cautioning that dealings with sanctioned entities or operations in Cuba's financial, mining, security, defence, or energy sectors could expose them to sanctions risk. This signals Washington's intent to use secondary pressure to isolate Havana from global capital flows.

This is the latest in a series of escalatory measures under the Trump administration's Cuba policy, which has consistently sought to tighten the economic vice on Havana. With GAESA subsidiaries, financial institutions, mining firms, and a Castro family member all now in the crosshairs, the sanctions architecture around Cuba is becoming markedly more comprehensive.
