evidence: What is the Wakhan Corridor and why is China worried about it? [...] The Wakhan region is known for being inaccessible for most of the year due to its high altitude, extreme weather and lack of roads. It is located in the remote Afghan province of Badakhshan, where three of the world’s major mountain ranges – the Hindu Kush, the Karakoram and the Pamirs – meet to form what is known as the Pamir Knot. The only access point at the border is at the southeastern end of the corridor, known as the Wakhjir Pass, which sits at nearly 5,000 metres (16,400 feet) above sea level. There is no road on the Afghan side of the pass.
