Since 1996, the OAS Mine Action Program has assisted the government of Costa Rica in its efforts of mine clearance, mine risk education (MRE) and victim rehabilitation. On December 10, 2002, the country became the first in the Americas to officially declare itself free of AP mines. Mine contamination within the country had been concentrated primarily along the northern border as a result of the conflict in Nicaragua. Costa Rica itself has never produced, imported, stockpiled or used AP mines.
