evidence: PoK comprises the so-called Azad Jammu and Kashmir (AJK) and Gilgit-Baltistan. Pakistan ceded a part of PoK, called the Trans Karakoram Tract, to China in 1963. AJK has its own constitution, a prime minister and a president, though real power is vested with Pakistan. The administration of Gilgit-Baltistan was handed over to Pakistan by AJK in 1949. It isn’t fully integrated into Pakistan and its constitutional status under that nation remains in a flux. Pakistan has often rejected demands to grant Gilgit-Baltistan the status of a fifth province, fearing it would compromise its demand for resolution of the Kashmir issue. [...] It is a disputed territory between India and China. India claims the border region as part of Ladakh, while China claims the area as part of the Xinjiang Uyghur Autonomous Region.
