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.
