Both India and Pakistan claim sovereignty over the entire Siachen region.
US and Pakistani maps in the 1970s and 1980s consistently showed a dotted line from NJ9842 (the northernmost demarcated point of the India-Pakistan cease-fire line, also known as the Line of Control) to the Karakoram Pass, which India believed to be a cartographic error and in violation of the Shimla Agreement.
In 1984, India launched Operation Meghdoot, a military operation that gave India control over all of the Siachen Glacier, including its tributaries.
Between 1984 and 1999, frequent skirmishes took place between India and Pakistan.
Indian troops under Operation Meghdoot pre-empted Pakistan's Operation Ababeel by just one day to occupy most of the dominating heights on Saltoro Ridge to the west of Siachen Glacier.
However, more soldiers have died from the harsh weather conditions in the region than from combat.
Pakistan lost 353 soldiers in various operations recorded between 2003 and 2010 near Siachen, including 140 Pakistani personnel killed in 2012 Gayari Sector avalanche.
Between January 2012 and July 2015, 33 Indian soldiers lost their lives due to adverse weather.
In December 2015, Indian Union Minister of State for Defence Rao Inderjit Singh said in a written reply in the Lok Sabha that a total of 869 Army personnel have lost their lives on the Siachen glacier due to climatic conditions and environmental and other factors till date since the Army launched Operation Meghdoot in 1984.
Both India and Pakistan continue to deploy thousands of troops in the vicinity of Siachen and attempts to demilitarise the region have been so far unsuccessful.
Prior to 1984, neither country had any military forces in this area.

Aside from the Indian and Pakistani military presence, the glacier region is unpopulated.
The nearest civilian settlement is the village of Warshi, 10 miles downstream from the Indian base camp.
The region is also extremely remote, with limited road connectivity.
On the Indian side, roads go only as far as the military base camp at Dzingrulma at 35.1663°N 77.2162°E, 72 km from the head of the glacier.
The Indian Army has developed various means to reach the Siachen region, including the Manali-Leh-Khardung La-Siachen route.
In 2012, Chief of Army Staff of the Indian Army General Bikram Singh said that the Indian Army should stay in the region for strategic advantages, and because a "lot of blood has been shed" by Indian armed personnel for Siachen.
According to the present ground positions, relatively stable for over a decade, India maintains control over all of the 76 kilometres (47 mi) long Siachen Glacier and all of its tributary glaciers, as well as all the main passes and heights of the Saltoro Ridge immediately west of the glacier, including Sia La, Bilafond La, Gyong La, Yarma La (6,100m), and Chulung La (5,800m).
Pakistan controls the glacial valleys immediately west of the Saltoro Ridge.
According to TIME magazine, India gained over 1,000 square miles (3,000 km²) in territory because of its 1980s military operations in Siachen.
In February 2016, Indian Defence Minister Manohar Parrikar stated in Parliament that India will not vacate Siachen as there is trust deficit with Pakistan and also said that 915 people have lost their lives in Siachen since Operation Meghdoot in 1984.
As per official records, only 220  Indian soldiers have been killed by enemy bullets since 1984 in Siachen area.
India has categorically stated that India will not pull its army from Siachen until the 110-km long AGPL is first authenticated, delineated and then demarcated.

The 1949 Karachi agreement only carefully delineated the line of separation to point NJ9842, after which, the agreement states that the line of separation would continue “thence north to the glaciers.”
According to the Indian stance, the line of separation should continue roughly northwards along the Saltoro Range, to the west of the Siachen glacier beyond NJ9842; international boundary lines that follow mountain ranges often do so by following the watershed drainage divide  such as t
