Wakil Ahmad Muttawakil told Reuters that an "inter-Afghan dialogue" is needed and that the discussion will "bear fruit."
Muttawakil surrendered to U.S.-led forces after the Taliban was toppled and was released from custody in 2003.
Taliban militants killed four Afghan police officers and seriously wounded three others in an ambush late in the evening of February 9 in southern Afghanistan.
Provincial police chief Afmatullah Alizai said the attack on a truck full of Afghan police took place in Kandahar Province's Panjwayi district.
The area is the site of the largest-ever NATO ground battle: more than 500 militants were killed there in September by NATO forces in an operation to clear the region of militants.
