The U.S. government announced Thursday new sanctions on companies linked to maritime oil transport, electronics and technology services, in its twelfth round of coercive measures against Cuba in 2026. The measures add to at least two executive orders and an oil blockade in place since January.

The Treasury Department’s Office of Foreign Assets Control targeted Cyprus-based Caroil Transport Marine and Panama-based Tentacool Commercial, along with Cuban firms Internacional Marítima and Petróleos Marítimos del Caribe (Petromarca), which the Trump administration links to the transport of crude oil and derivatives to or from Cuba.

OFAC also listed Cuban state companies Cubaelectrónica, an importer of electronic supplies and equipment, and Tecnosime, a marketer of technical and technological services, together with Chinese corporations CEIEC and Beijing H&C Technologies.

Five vessels were listed as “blocked property” for carrying crude oil or derivatives to the Caribbean country, tied to Caroil and Petromarca.

Sanctioned sectors have included energy, oil, mining, construction, maritime and port, international medical services, exports and imports, remittances and finance.
