Cuba: Key Industries

Cuba's economy is directed largely by the state, which owns and manages most major industries, though a private sector has grown modestly since reforms began in the early 2000s. As of 2026, tourism remains the country's leading source of foreign exchange, employing roughly two-fifths of the workforce and drawing visitors to Havana's colonial architecture, white-sand beaches, and UNESCO World Heritage sites such as Trinidad and Santiago de Cuba.

Sugar, once the dominant pillar of the Cuban economy and a defining export since the colonial period, has declined sharply in output but remains part of the island's agricultural base alongside tobacco, citrus, coffee, and livestock. Mining contributes nickel and cobalt, among the country's most valuable mineral exports, while the energy sector depends heavily on imported and domestically refined petroleum to meet electricity demand.

Cuba has also built a state-owned biotechnology and pharmaceutical sector, developing vaccines and treatments such as Heberprot-P for diabetic foot ulcers, and exporting medical products alongside nickel, sugar, and tobacco. As of 2026, China ranks among Cuba's leading trading partners, together with Spain and other European and Latin American markets, following the decline of the Soviet-era trade relationship and the more recent contraction of Venezuelan oil shipments that once anchored the island's energy supply.
