evidence: The region is divided amongst three countries in a territorial dispute: Pakistan controls the northwest portion (Northern Areas and Kashmir), India controls the central and southern portion (Jammu and Kashmir) and Ladakh, and the People's Republic of China controls the northeastern portion (Aksai Chin and the Trans-Karakoram Tract). India controls the majority of the Siachen Glacier area, including the Saltoro Ridge passes, whilst Pakistan controls the lower territory just southwest of the Saltoro Ridge. India controls 101,338 km2 (39,127 sq mi) of the disputed territory, Pakistan controls 85,846 km2 (33,145 sq mi), and the People's Republic of China controls the remaining 37,555 km2 (14,500 sq mi). [...] Though these regions are in practice administered by their respective claimants, neither India nor Pakistan has formally recognised the accession of the areas claimed by the other. India claims those areas, including the area "ceded" to China by Pakistan in the Trans-Karakoram Tract in 1963, are a part of its territory, while Pakistan claims the entire region excluding Aksai Chin and Trans-Karakoram Tract. The two countries have fought several declared wars over the territory. The Indo-Pakistani War of 1947 established the rough boundaries of today, with Pakistan holding roughly one-third of Kashmir, and India one-half, with a dividing line of control established by the United Nations. The Indo-Pakistani War of 1965 resulted in a stalemate and a UN-negotiated ceasefire.
