What specific sectors does the Trump administration's new sanctions on Cuba target, and how do they aim to affect foreign companies operating there?

The new sanctions target defense, mining, finance, and security sectors, and authorize Washington to penalize almost any non-U.S. citizen or entity doing business in Cuba. According to the article, the measures are designed to 'terrify' international companies—such as Turkey’s Karpowership (energy) and Canada’s Sherritt International (nickel and cobalt mining)—into withdrawing from the island, while also threatening financial institutions that process transactions with certain Cuban individuals or entities with exclusion from the U.S. banking system.

How did Cuban President Miguel Díaz-Canel respond to Trump’s military threats against Cuba, and what broader appeal did he make?

President Díaz-Canel called Trump’s military threats 'dangerous and unprecedented' and urged the international community—and the U.S. public—to take note and collectively decide whether such 'drastic criminal act' would be allowed, asserting that 'No aggressor, no matter how powerful, will force Cuba to surrender.'
