due diligence process, which included the conclusive and positive findings of a cumulative impact study and a subsequent review of the study undertaken by independent experts (the Hatfield report)". Gualeguaychú Assembly's strategy On 20 October the Gualeguaychú Assembly started discussing the possibility of new road blockades and a blockade of the Uruguay River to prevent supplies from reaching Botnia's mill. Assembly member Martín Alazar told Uruguayan newspaper El Observador that "River blockade is likely to happen, we have studied several alternatives and places". Furthermore, the activists are working on challenging the technical reports issued by the International Financial Corporation earlier this week. Other members of the Assembly claimed that "road blockades are, today, the best argument" to stop the construction of the mills, and that they are being forced "to take violent action" faced with the lack of action from the governments. November 2006 Wall blockade On 3 November (Friday), the Gualeguaychú Assembly decided to stage a new blockade for the duration of the weekend, this time erecting a concrete block wall. The 1.8-meter-high wall blocked International Route 136 almost completely, and displayed a sign in English and Finnish against the pulp mills. On the afternoon of 5 November, the Assembly dismantled the wall and lifted the blockade as planned. King Juan Carlos agrees to intercede During the XVI Ibero-American Summit in Montevideo, presidents Kirchner and Vázquez avoided a meeting between them. However, Kirchner asked King Juan Carlos of Spain to facilitate the renewal of negotiations between the two countries. The proposition was accepted by the Uruguayan government. Trinidad Jiménez, Spanish Secretary of State for Ibero-America, explained that the monarch would not be a mediator, yet he would facilitate the easing of tensions within this conflict. The Uruguayan government, in turn, stated again it would not agree to meetings at the presidential level if a road blockade is in place, as it was at the time. José Pouler, a member of the Gualeguaychú Assembly, expressed support for the facilitation, calling it "a good initiative", though he pointed out that, to them, the construction of the mills on the river "is not negotiable".
