The visit comes amid accusations from senior Afghan intelligence officials Islamabad still supports the Taliban and warnings from Kabul's Western allies that the rebels are being bolstered by the ability to shelter in Pakistan.
The two countries have agreed on tribal councils, or jirgas, of community leaders from each country to find a solution to the violence.
However, commentators say there are differences on who should sit on these councils.
Afghanistan wants all tribes to take part in the councils, not just the Pashtuns from the main Pakistani border areas.
Some Afghan and Pakistani leaders say elements of the Taliban must be included if there is to be any peace.
Kabul wants Afghan President Hamid Karzai and Pakistan's President Pervez Musharraf to lead the first jirga, but no time or place has been set.
