It may seem difficult to find an upshot to the massive natural disaster that hit Haiti last month. Yet the earthquake did lead to mended fences with the Dominican Republic. “The Dominicans were the first to arrive with help, with doctors, food, and aid,” says Alice Blanchet, a special advisor to Haitian Prime Minister Jean-Max Bellerive. “They were stellar.” Despite long-running tensions between Port-au-Prince and Santo Domingo, the disaster has drawn the neighbors closer together. As The Economist put it, the result is “[a] break in a history of mistrust.” But how long that break will last could be tested, particularly given recent changes in Dominican immigration policy.
