The important oasis of Yarkand (Shache) was once the seat of an ancient Buddhist Kingdom and an important caravanserai on the Southern Silk Road. Today it is a predominantly Uighur city with a population of 375,000 producing cotton, wheat, corn and fruit (notably pomegranates, pears and grapes) as well as oil and natural gas. In times past Yarkand was of particular importance as the northern terminus for the strategically significant trade route to Leh, capital of Ladakh in Indian-administered Kashmir, across the Karakoram Pass (5,575m., 18,286 ft).
