[2] It links Wakhan in Afghanistan with the Tashkurgan Tajik Autonomous County in Xinjiang, China, at an altitude of 4,923 metres (16,152 ft).

[2] With a difference of 3.5 hours, the Afghanistan–China border has the sharpest official change of clocks of any international frontier (UTC+4:30 in Afghanistan to UTC+8, in China).

[5] Construction of the road from Sarhad-e Wakhan to Bazai Gonbad and then to the Wakhjir Pass in the northeast has started in late 2023.

[12] The terrain is extremely difficult, although Aurel Stein reported that the immediate approaches to the pass were "remarkably easy".

It is believed that the Chinese Buddhist pilgrim Xuanzang traveled via this pass on his return trip to China in approximately 649 AD.

[3][23] It is believed that in more recent times, the pass is sometimes used as a low-intensity drug smuggling route, and is used to transport opium made in Afghanistan to China.

[24] Afghanistan has asked China on several occasions to open the border in the Wakhan Corridor for economic reasons or as an alternative supply route for fighting the Taliban insurgency.

However, China has resisted, largely due to unrest in its far western province of Xinjiang, which borders the corridor.
