Isla Brasilera/Ilha Brasileira is a territory of Brazil
Brazilian Island (Portuguese: Ilha Brasileira; in Standard Spanish: Isla Brasileña; in Portuñol/Portunhol: Isla Brasilera1) is a small uninhabited river island at the confluence of the Uruguay River and the Quaraí (Cuareim) River, between the borders of Argentina, Brazil and Uruguay, which is disputed by the two latter countries. The island is approximately 3.7 km (2.3 mi) long by 0.9 km (0.6 mi) wide, and it is located at 30°10′56″S 57°37′43″W. The island has long been claimed by both Brazil and Uruguay. Brazilian officials claim that the island is within their municipality of Barra do Quaraí, state of Rio Grande do Sul. Uruguayan officials claim that the island is part of their municipality of Bella Unión, in Artigas Department.[1] However, neither country has shown interest in actively enforcing its claims to the island, for example by sending troops there. Like the other territorial dispute between Brazil and Uruguay in the vicinity of Masoller, it has not prevented close and friendly diplomatic and economic ties between the two countries.
