Brazil's neighbors in south america are generally well represented in Rio de Janeiro, and all of them with no exception are represented in the capital, Brasília.

Brazil and most other countries of south america are part of the Unasur, which is a multinational block similar to the widely known European Union, with economical and political objectives of union and development for all members - Some of the members of this group have already abolished the need for visas for residents of other member nations, in which case a national ID is enough to cross the border.
