The Treaty, adopted in 1969, aims to promote the harmonious development and physical integration of the Plata River Basin and its areas of influence.
The Contracting Parties undertake to promote the identification of areas of common interest, to conduct studies, programs and works and to formulate legal instruments to, inter alia, facilitate navigation, promote the rational use of water resources and preserve animal and plant life (art.1).
