Uruguay is a member of the Rio Group, an association of Latin American states that deals with multilateral security issues (under the Inter-American Treaty of Reciprocal Assistance). Uruguay's location between Argentina and Brazil makes close relations with these two larger neighbors and MERCOSUR associate members Chile and Bolivia particularly important. Usually considered a neutral country and blessed with a professional diplomatic corps, Uruguay is often called on to preside over international bodies. Uruguay is a member of the Latin American Integration Association (ALADI), a trade association based in Montevideo that includes 10 South American countries plus Mexico and Cuba.
