El papel de la paradiplomacia entre el norte de Chile y el sur del Perú: Antecedentes históricos, limitaciones institucionales y nuevos desafíos "posfallo de la haya"

Tacna and Arica have a mutual irrefutable colonial and republican history; however, after the Treaty of Ancon (1884) and until now, in which La Haya verdict on water borders has been the last law suit, the nation states of Peru and Chile have put pressure on border relationships until the limits of diplomacy. Here the paradiplomatic role is analyzed that actors of the societies of Tacna and Arica have performed, with the purpose of achieving a social harmony to benefit them, taking advantage of the economic complementarity of the valley (Tacna) and the port (Arica). Through the implementation of different cross-border neighboring agreements, to deal with specific local cooperative aspects, paradiplomatic actors from Tacna-Arica have built a cross-border identity, challenging even some nationalist practices.
