International boundaries are often blurred by the processes of globalization, but in South America some maritime borders remain contested. For instance, Chile and Peru, neighbors that have enjoyed sustained economic development over the past few years, remain at odds over approximately 38,000 square kilometers of sea located along their maritime border.

Bilateral negotiations between the two countries were first held in 1980 but no agreement was reached. In 2008, Peru took the case to the International Court of Justice (ICJ) which, in turn, considered the issue at a public hearing in December 2012. The ICJ is expected to make a ruling on the dispute in mid-2013.

In the meantime, Peru continues to argue that the maritime border has not yet been defined by any agreement, with documents signed in the 1950s only relating to access to fishing grounds.  Lima also claims that maritime limits should run diagonally south-west from the land border. » More
