Personally I agree with this map, which shows the isolation of the South American countries due to geography. As a Uruguayan, I consider Argentina and Brazil to be my immediate neighbors (with Argentina having an intense socio-cultural relationship, with Brazil, a relationship less due to the cultural and idiomatic difference). Farthest neighbors are Paraguay and Chile, and very distant relations with Bolivia, Peru, Ecuador,Colombia and Venezuela (with the latter country, relations have increased in recent years due to the ideological closeness of our left-wing governments in recent years and the Chavista regime, and by the intense Venezuelan immigration that we have received). Mexico, Central America, the Caribbean? ... almost another planet ....and the Guianas do not exist for us ...
