Chile and Peru Disagreements

Peru-Chile border row escalates (BBC News); "President Alejandro Toledo of Peru has signed a law that redraws the sea border with Chile, deepening a row between the two Latin American nations. The bill, approved by Congress unanimously on Thursday, grants Peru 37,900 sq km (14,600 sq miles) of fishing waters in the Pacific Ocean. Chile currently controls the area, and says the law violates treaties signed in the 1950s."

Peru and Chile have a history of border disputes dating back to the 19th century. Chile fought the War of the Pacific against Peru and Bolivia from 1879 to 1883, winning Bolivia's outlet to the sea and extensive areas from Peru.
In more recent years, the two countries have disagreed over the appellation rights to Pisco, the brandy or aguardiente distilled from the white muscat grapes grown in the area around Pisco and the Valle del río Elqui in central Chile. Furthermore, Peru suspended free-trade talks and confidence-building measures with Chile and refused to support Chile to lead the Organisation of American States. Chile refuted Peruvian claims that Chile supplied arms to Ecuador during a 1995 war with Peru.
