Illegal trade across the Haiti/Dominican Republic border has serious financial and security implications. Contraband undermines legitimate business on both sides of the border and deprives the public sector—especially the cash-strapped government of Haiti—of much-needed revenues. It also undermines rule of law and public security by fueling corruption and strengthening criminal organizations.  After two research trips to both Haiti and the Dominican Republic, CSIS Americas has produced a summary report of the issue of illicit border trade between Haiti and the Dominican Republic, incorporating several case studies and policy recommendations for preventing further cross-border illicit trade and revenue loss.
