Lima, Treaty of (1929)

Treaty of (1929) Lima, a diplomatic agreement between Chile and Peru, signed on 16 April 1929, that finally resolved the Tacna-Arica Dispute. Under the Treaty of Ancón, signed in 1883, Chile retained temporary possession of the two provinces Arica and Tacna. It refused, however, to carry out the remaining terms of the treaty, which called for a plebiscite to determine the ownership of this territory. After years of haggling, Peru and Chile signed the Treaty of Lima. According to this arrangement, Chile retained Arica but Tacna was awarded to Peru along with 6 million pesos. While it settled the long-simmering boundary dispute between Chile and Peru, the Treaty of Lima unfortunately did not deal with Bolivia's loss of its seacoast, an issue (dating from the War of the Pacific) which continues to complicate the relationship between Santiago and La Paz to this day.
