About a kilometer southeast of the Sia Kangri summit is the tri point where territories controlled by India, Pakistan and China meet.

The land to the northeast is part of the Trans-Karakoram Tract, controlled by China under a 1963 border agreement with Pakistan but is claimed by India.

Indira Col which is 3 km to the east is India's northernmost point.

[3] Sia Kangri was first climbed in 1934 by the International Himalaya Expedition led by the Swiss-German mountaineer Günter Dyhrenfurth.

The summit party included Hettie Dyhrenfurth, who thereby set the women's world altitude record, which stood for 20 years.
