Peru and Chile's maritime dispute at the Hague

The International Court of Justice in the Hague has begun hearing arguments from Peru and Chile in a dispute over major areas of sea off their respective coasts.

Peru lodged the case laying claim to a large maritime tract currently controlled by Chile, and another area considered by Chile to be international waters.

Disputes between the South American neighbours go back a long way and historians believe this could be a final chapter of the War of the Pacific of the late 19th century.
