Latin Americans don't associate Guyana and Belize as Latin America, beyond the proximity. Latin Americans are associated with Spanish and Portuguese mainly (romance languages). Also, the colonization by Spain and Portugal. Guyana and Belize are associated specifically with the Caribbean area.
That's why the original says "Latin" in quotes, but geographically they're in Central/South America and, as this discussion has illustrated, that means "Latin" as far as most Americans are concerned.
