evidence: - Brazil – Uruguay: El Rincón de Artigas is a territory in the shape of a triangle located in the south of Brazil and which Uruguay argues forms part of the northern department of Artigas. The extension of the land is 237 km2. The Uruguayans maintain that due to an error of delimitation in the 19th century, the territory remained in the hands of Brazil; however, the claim does not have a legal process, so Brazil does not recognize Uruguay’s claims.
