US sanctions Raúl Castro's grandson and Cuba's Banco Exterior de Cuba

The United States has imposed sanctions on a grandson of Raúl Castro and Banco Exterior de Cuba, escalating pressure on the Cuban regime. Secretary of State Marco Rubio framed the move as part of President Trump's vision of a free Cuba. This continues the established pattern of US sanctions against Cuban officials and entities, though targeting a family member of the former leader adds a personal dimension.
