Someone else will hopefully have more specific details on the situation.

In general the economic situation isn’t great due to the blockade since as an island nation they have to Import anything (like oil) that isn’t a natural resource on the island. Blackouts and other energy issues have been a problem due to that.

Trump recently increased the blockade and I know due to COVID their tourism industry was hit pretty hard.

Some silver linings to the situation:

China has provided solar panels that should help strengthen their grid and provide them a source of energy that can’t be blockaded.

They recently became a BRICS partner member which should hopefully give them some ability to trade even with the blockade.

Vietnam recently has raised millions in an ongoing effort to send donations to Cuba.
