Border disputes [ edit ]
With Bolivia [ edit ]
With Uruguay [ edit ]
A triangular region, named
Rincão de Artigas in Portuguese, is claimed by both Uruguay and Brazil. The dispute is due to a disagreement as to which stream should be called Arroyo de la Invernada and form the official border between the two countries.
Brazilian Island, a river island at the junction of the Quaraí River and the Uruguay River on the border between Argentina, Brazil, and Uruguay is claimed by both Uruguay and Brazil.
