Pakistan's Prime Minister Shahid Khaqan Abbasi arrived in the Afghan capital Kabul on Friday on a one-day visit aimed at improving relations between the countries.
Abbasi will meet President Ashraf Ghani and the country's Chief Executive Abdullah Abdullah, said a spokesman for the Afghan presidential palace, Dawa Khan Minapaal.
Establishing a peace process between the Afghan government and the Taliban was top of the agenda, he added.
It is the first visit by a Pakistani prime minister to Afghanistan in nearly three years.
Afghanistan and the US accuse Islamabad of providing support to Taliban militants fighting the Afghan government and international forces in the country. Pakistan rejects this accusation.
The Afghan Taliban have been expanding their military offensives since the end of the Nato combat mission in December 2014. 
They are now estimated to control or influence at least 14% of the country, while another 30% is being fought over.
The US has in recent months increased pressure on Pakistan by, for example, cutting more than $1bn in military aid.
Friday's visit was also overshadowed by accusations from Kabul that Pakistan conducted an airstrike on alleged Pakistani extremists hiding out in the Afghan border province of Kunar on Wednesday.
A Pakistani military source on Thursday denied the charge, saying the military operated only on its own soil.
