Accompanied by his wife and children, as well as several members of his cabinet, the winner of this year's Nobel Peace Prize for his efforts to broker a peace deal with the Revolutionary Armed Forces of Colombia (FARC) said the funds would go toward "projects, foundations or programs that deal with victims and reconciliation."
"We're going to persevere, we will persist, persist, persist and persist until we implement the agreement that was signed" with the FARC guerrillas, Santos said adding: "if we have to make adjustments to what we have already agreed, we will make those adjustments."
Colombia's five-decade conflict has killed more than 260,000 people, left 45,000 missing and forced nearly seven million to flee their homes.
Under the peace deal, the FARC was to relaunch as a political party. But rightwing hardliners led a campaign against the accord, arguing it offered the rebels impunity for massacres, kidnappings and other crimes committed during the conflict.
The Nobel Peace Prize is a gold medal, a diploma and a check for eight million Swedish kronor (around USD 925,000), which will be presented at a ceremony in Oslo on December 10.
