Pakistan and India will hold two- day talks on the Siachen issue from Friday.
Indian Defence Secretary Shekhar Dutt, leading a nine-member delegation from India, arrived here on Thursday. Pakistani team would be led by Pakistan's Secretary Defence Kamran Rasool.
The talks are part of the on-going process of composite dialogue between the two countries for resolution of all the outstanding issues.
The Siachen glacier is located in the eastern Karakoram range in the Himalaya mountains. It is one of the five largest glaciers in the Karakoram, ranging from an altitude of 5,753 meter above the sea level at its source to its snout at 3,620 meter.
India insists that "iron-clad" evidence of Pakistani military positions on the Siachen area of the disputed region is needed before demilitarization of the world's highest battlefield can begin.
Pakistan fears that setting out its positions would be tacit acceptance of India's claims to Siachen and the area as a whole.
India and Pakistan fought a fierce skirmish on Siachen in 1987 and held several rounds of discussions on the glacier since the resumption of peace talks between two south Asian rivals in January 2004.
