Brazil finishes its war with Cono Sur and fully occupied Chile and Argentina. As Brazil becomes hegemon in South America, the Brazilian government hosted the Treaty of São Paulo which ends South American War between victories nations of Brazil and Bolivia, and defeated nations of Chile and Argentina, held in São Paulo, Brazil.
Under the treaty,
Brazil annexes Peru (admitted into Hispanican Region),
some of northern parts of Chile (admitted into Hispanican Region),
Uruguay and northeastern part of Argentina (admitted into Brazilian Region),
while Bolivia annexes northern part of Argentina.
Brazil also allows Brazilian soldiers and tanks to station these in newly annexed areas of Brazil.
