The election of that party's nominee, Miguel Juárez Celman, to the presidency in 1886 resulted in his appointment as Foreign Minister, during which he pursued regional international law agreements and negotiated a treaty with Chile to help settle the Puna de Atacama dispute, in which Argentine claims over Tarija, Bolivia were dropped for a greater share of the Puna de Atacama region (prized for its copper deposits).
In 1898 it was ceded to Argentina in exchange for recognition of Tarija as part of Bolivia.
Between 1816-1898, the region was part of Argentina, and was ceded to Bolivia in exchange for Puna de Atacama.
