In the 1970s and early 1980s, in the pretext of climbing the high peaks on this glacier, Pakistan sent expeditions with permits issued by the Government of Pakistan.
The idea was to reinforce claim on the area, as these expeditions arrived with a permit obtained from the Government of Pakistan.
In 1984, when the Pakistan army attempted to move into the region, India launched a successful military operation and has since maintained control over all of the Siachen Glacier and its tributaries.
