evidence: Between China, Afghanistan, Tajikistan and Pakistan, inside the Pamir Knot, lies the Wakhan corridor. This strip of land sandwiched between the four countries was created as a buffer between the territories of British India and Tsarist Russia in the 19th century, which was then formally demarcated between the Kingdom of Afghanistan and the Chinese People’s Republic in November 1963. The Wakhan corridor has historically been an important transit path of the ancient Silk Road route. According to Alexander Farhad, in the fourth and fifth centuries, the passes across the Pamir led Chinese pilgrims to the Buddhist centers in today’s Afghanistan and India and were used by Persian merchants to sell their goods in the Chinese market. Nazif Shahrani, in his The Kirghiz and Wakhi of Afghanistan: Adaptation to Closed Frontiers and War, maintains that until the collapse of Mughal Empire in India, Wakhan was one of the main routes for traders and merchants between India, China and major cities like Bactria and Bukhara in modern-day Afghanistan and Central Asia. It was due to the rapidly developing use of sea routes by Westerners to reach India and China in the late 15th century that the importance of the ancient Silk Road from Rome to China went into decline. [...] If built, the Wakhan corridor would be the least costly trade route between China, Afghanistan, Tajikistan and Pakistan compared to the current alternatives. This should compel the four countries to transform this land buffer into a bridge between them.
