Presidents Néstor Kirchner of Argentina and Tabaré Vázquez of Uruguay reached a sort of truce...in the ongoing conflict over pulp mills that two foreign companies - Botnia from Finland and ENCE from Spain - are building on the Uruguay River, which according to activists and officials in Argentina will cause water and air pollution. The agreement...[provides for] work on the two factories to be suspended for 90 days until their environmental impact could be determined by independent experts. In exchange, the Argentine president promised to take measures to get activists and local residents of towns along the border...to lift the roadblocks that have been stopping traffic across bridges connecting the two countries...Botnia and ENCE say they will use the most advanced technologies in order to minimise the risks of pollution [also refers to Celulosa Arauco y Constitución (Celco)]
