VERON, Dominican Republic (AP) — As soaring violence and political turmoil grip neighboring Haiti, the Dominican Republic will hold elections Sunday that have been defined by calls for more crackdowns on migrants and finishing a border wall dividing the countries.

Politics in the two Caribbean nations sharing the island of Hispaniola have long been intertwined. Haiti’s spiral into chaos in recent years has coincided with a harsh crackdown by its Dominican neighbor.

President Luis Abinader, a clear frontrunner race as he seeks reelection in the presidential race, has begun to build a Trump-like border wall along Haiti’s border and carried out mass deportations of 175,000 Haitians just last year. Dominicans also will be choosing members of Congress.

“We will continue to deport everyone who is illegal from any country,” Abinader said in a debate in late April. “A society that doesn’t do that is chaos and anarchy.”
