Venezuelan President Hugo Chávez congratulated his Bolivian counterpart Evo Morales for the Bolivians' decision to ratify his mandate in a recall vote last Sunday, Venezuelan President's Office reported.

During a telephone conversation with Morales on Sunday night, Chávez assured Morales of the Venezuelan government support in his search of a "peaceful transformation" of Bolivia, through a "democratic and cultural" revolution, DPA reported.

"Once again, the truth triumphs over the campaigns of the empire (the United States) with this glorious election day, which is the most vivid historic demonstration of the Bolivian people's desire to control its destiny," Chávez told Morales.

For its part, the Organization of American States (OAS) said that Bolivian political leaders are obliged to sit down to reach an accord after the recall vote. The OAS chief recommended to set clear rules of negotiation, EFE reported.
