Pakistan and Afghanistan began a four-day track-II dialogue in Islamabad on Wednesday to explore ways for improvement in relations between the two neighbouring countries. A 13-member Afghan delegation, led by former member of the parliament Khalid Pashtoon, arrived in Islamabad and both sides held informal discussion on Tuesday night at a reception. The delegates will discuss the impact on Pak-Afghan relations of President Ashraf Ghani's visit to Pakistan in June this year.
