THE HAGUE, Netherlands (AP) — The Peruvian government asked the United Nations' highest court Monday to set a maritime border between Peru and Chile, in a case that could greatly expand the amount of rich seas under Peru's control off the two Andean neighbors' Pacific coasts.
Peru launched the case at the International Court of Justice in 2008, arguing that there has never been a maritime boundary established and that two agreements Chile claims set the border are non-binding and merely denoted some fishing zones. Chile insists the border was clearly set in treaties signed in 1952 and 1954.
Chile and Peru are among the world's top producers of fishmeal, and the waters off their coasts are an important source of income for both countries. If Peru wins, it could gain control over more than 60,000 square kilometers (23,166 square miles) of ocean that Chile has controlled for the last 60 years.
Peru is presenting its arguments Monday and Tuesday. Chile will respond Thursday and Friday.
Peru lawyer Alain Pellet told the court there is "a flagrant lack of any maritime delimitation" between the two countries and that Chile's proposed border "radically cuts off Peru's access to the high seas."
Pellet said Peru wants the 16-judge court to draw a line that will equally divide the sea off the two countries' coasts based on established international law. "Peru asks neither more nor less than the laws of the sea grant to all coastal states," he said.
Peru and Bolivia waged a joint war against Chile from 1879-1884 and lost badly, with Chile seizing a chunk of southern Peru as well as all of Bolivia's coastline. Chile has long held that all border questions were resolved by several 20th century treaties.
Chilean President Sebastian Pinera last week said the long-awaited case in The Hague boils down to defending "a cause that belongs to us all, such as defense of our oceans ... and our sovereignty."
Chilean representative Maria Teresa Infante Caffi told reporters outside the courtroom that her country's standpoint was not changed by Peru's arguments. "The central point for Chile is the existence and validity of the limits that were established through bilateral agreements between the two countries," she said.
Rulings by the world court are final and binding.
