The communists suspended peace talks in 2004, accusing the government of instigating their inclusion on US and European terror lists.
The government has opened talks and has a cease-fire agreement with the Muslim separatist Moro Islamic Liberation Front.
The president's comments come as the military is stepping up its offensive against the Abu Sayyaf on two southern islands where around 55 troops and dozens of fighters have been killed since July.
