Disputes - international:
Costa Rica and Nicaragua regularly file border dispute cases over the delimitations of the San Juan River and the northern tip of Calero Island to the International Court of Justice (ICJ); in 2009, the ICJ ruled that Costa Rican vessels carrying out police activities could not use the river, but official Costa Rican vessels providing essential services to riverside inhabitants and Costa Rican tourists could travel freely on the river; in 2011, the ICJ provisionally ruled that both countries must remove personnel from the disputed area; in 2013, the ICJ rejected Nicaragua's 2012 suit to halt Costa Rica's construction of a highway paralleling the river on the grounds of irreparable environmental damage; in 2013, the ICJ, regarding the disputed territory, ordered that Nicaragua should refrain from dredging or canal construction and refill and repair damage caused by trenches connecting the river to the Caribbean and upheld its 2010 ruling that Nicaragua must remove all personnel; in early 2014, Costa Rica brought Nicaragua to the ICJ over offshore oil concessions in the disputed region

Trafficking in persons:
current situation: Costa Rica is a source, transit, and destination country for men, women, and children subjected to sex trafficking and forced labor; Costa Rican women and children, as well as those from Nicaragua, the Dominican Republic, and other Latin American countries, are sex trafficked in Costa Rica; child sex tourism is a particular problem with offenders coming from the US and Europe; men and children from Central America, including indigenous Panamanians, and Asia are exploited in agriculture, construction, fishing, and commerce; Nicaraguans transit Costa Rica to reach Panama, where some are subjected to forced labor or sex trafficking
tier rating: Tier 2 Watch List – Costa Rica does not fully comply with the minimum standards for the elimination of trafficking; however, it is making significant efforts to do so; anti-trafficking law enforcement efforts declined in 2014, with fewer prosecutions and no convictions and no actions taken against complicit government personnel; some officials conflated trafficking with smuggling, and authorities reported the diversion of funds to combat smuggling hindered anti-trafficking efforts; the government identified more victims than the previous year but did not make progress in ensuring that victims received adequate protective services; specialized services were limited and mostly provided by NGOs without government support, even from a dedicated fund for anti-trafficking efforts; victims services were virtually non-existent outside of the capital (2015)

Illicit drugs:
transshipment country for cocaine and heroin from South America; illicit production of cannabis in remote areas; domestic cocaine consumption, particularly crack cocaine, is rising; significant consumption of amphetamines; seizures of smuggled cash in Costa Rica and at the main border crossing to enter Costa Rica from Nicaragua have risen in recent years
