evidence: Today, China occupies 20% of the original state of J&K, including the areas it surreptitiously encroached upon in the 1950s or seized during its 1962 invasion of India as well as the trans-Karakoram tract (comprising mainly the Shaksgam Valley) that Pakistan ceded to it under the 1963 Sino-Pakistani Frontier Agreement. That transfer of territory was a unique case in modern history of one nation gifting another with a sizable slice of the land that it had gained control of earlier in a war with a third country (India).
