Uruguayan government to reciprocate (suspending the construction of the mills in order to discuss). Uruguayan Chancellor Gargano had previously stated that freeing the roads was a sine qua non condition to start negotiations. The Environmental Assembly of Colón, on the other hand, decided to continue blocking Route 135 and the international pass over the General Artigas Bridge, 80 km north of Gualeguaychú. Suspension of works On 26 March, one of the companies building the pulp mills, Botnia, announced that it would suspend the installation works for 90 days "in order to contribute to the opening of dialogue and answering to the request of Presidents Tabaré Vázquez and Néstor Kirchner." Botnia is so far the largest private investment in the history of Uruguay, and it had completed 45% of the project, but not started the mills themselves. The news caused concern among European stockholders. ENCE, whose construction had not yet started at all, also informally agreed to suspend the works. Soon afterwards, the ombudsman of the World Bank, Meg Taylor, concluded that the review carried out by the IFC about the pulp mills had been "incomplete" and its procedures not rigorous enough. These conclusions were delivered to the government of Entre Ríos, which in turn passed them on to President Kirchner to be analyzed in the upcoming presidential meeting in Colonia, Uruguay. On 30 March, Botnia sent the construction workers union (SUNCA) a communique which stated that the suspension had been revised and work should continue normally. The company would halt the works for only ten days. When this was confirmed, the Colonia meeting, which had been postponed once already, was cancelled. On 5 April, after deliberations, the Gualeguaychú Assembly resumed the blockade of Route 136. April 2006 The relationship between the political actors of both countries became tense after the resumption of the blockade. Catholic Church leaders in both vowed to facilitate the dialogue (though specifically not to act as mediators). The governments of Finland and Spain denied the possibility of intervening in the affairs involving Botnia and ENCE. The Finnish Minister of Foreign Trade and Cooperation for Development, Paula Lehtomäki, cancelled a visit to Argentina citing a concern that she might not be welcome, and stated that the conflict was to be solved among Argentina, Uruguay and the two private companies. Uruguay threatened to resort to the World Trade Organization, since the blockades "violate basic principles of international commerce"
