Foreign relations of Peru

is an important first-tier state in South America,[1] Peru has been a member of the United Nations since 1945,[2] and Peruvian Javier Pérez de Cuéllar served as UN Secretary General from 1981 to 1991.

[160] Both countries established diplomatic relations on 11 July 1990[163] In November 1999, Peru and Chile signed three agreements which put to rest the remaining obstacles holding up implementation of the 1929 Treaty of Lima, which officially ended the 1879 War of the Pacific.

Peru's position was that the border has never been fully demarcated, but Chile disagreed reminding on treaties in 1952 and 1954 between the countries, which supposedly defined seaborder.

However, Chile's Michelle Bachelet and Peru's Alan García have established a positive diplomatic relationship, and it is very unlikely any hostilities will break out because of the dispute.

Nevertheless, in early April 2007, Peruvian nationalistic sectors, mainly represented by left wing ex-presidential candidate Ollanta Humala decided to congregate at 'hito uno' right at the border with Chile, in a symbolic attempt to claim sovereignty over a maritime area known in Peru as Mar de Grau (Grau's Sea) just west of the Chilean city of Arica.

Peru's President Alan García and Mexico's Felipe Calderón signed a joint declaration in April 2011 aimed at deepening the two countries' friendship, cooperation, integration, trade, investments and the permanent fight against poverty and organized crime.
