Argentines protest Uruguayan paper mills, 2005-2008
Argentina and Uruguay have a history of friendly diplomatic relations, with their countries sharing similar heritages, mutual alliances and significant cultural and political ties. However, following the 2005 announcement of the construction of two paper mills on the Uruguayan side of the Uruguay River (which serves as a boundary between the two countries), Argentina and Uruguay experienced their first significant diplomatic tensions since the 1970s.
