"On the part of the (government) panel, we have imposed a timeline of nine to 12 months," Silvestre Bello, the government delegation's head of negotiations, told reporters.
The government and the rebels hope to breathe new life into the peace process by discussing simultaneously -- contrary to previous attempts -- the outstanding issues of social and economic reforms, political and constitutional reforms, and an end to hostilities.
"With this new approach we are quite confident that we will be able to achieve our timetable," Bello said.
The head of the rebels' delegation, Luis Jalandoni, confirmed the timetable but was more cautious in his optimism about reaching a political settlement after 30 years of failed talks.
"I think we will try to do it in one year but it might take a little more time because the negotiations on social and economic reforms could take more time," he told AFP.
"It's more complicated than some may think," he said.
