President Santos of Colombia says the Nobel Peace Prize, which he is due to receive in Oslo on Saturday, helped him seal an agreement with leftist rebels.
The award provided the impetus for new talks leading to a revised deal, signed last month between the government and the FARC.
A previous peace plan put forward by Santos was narrowly defeated in a referendum in October.
Juan Manuel Santos spoke in Norway on the eve of receiving his prize, saying the end of the conflict could have widespread economic and environmental benefits.
“The Nobel prize award was announced and it came like a gift from heaven, because it gave us a tremendous push. People in Colombia interpreted it as a mandate from the international community to persevere, to continue striving to achieve a new peace agreement, so it helped very very much,” he said.
