The Wesh–Chaman border crossing is one of the major international border crossings between Afghanistan and Pakistan. Located on the Pak-Afghan border, it leads north from the town of Chaman, Balochistan into Wesh in Spin Boldak, Kandahar province. More generally, it links the two provincial capitals: Quetta and Kandahar.
A brick, double-arched Friendship Gate, rising three stories tall, was erected in 2003. The gate facing towards Balochistan bears the words "Proud Pakistani" and "Pakistan First". Its official hours run from morning to sunset, though smuggling may continue at night.
The Wesh-Chaman border crossing has been used by international forces (ISAF) in Afghanistan as part of a major supply route stretching from the Port of Karachi to Kandahar, with roughly 60 to 100 trucks traversing Chaman daily. On January 18, 2010, ISAF commander General Stanley A. McChrystal visited the site after discussing the crossing's efficiency with Pakistani authorities. A US-run Forward operating base (FOB) is located in Spin Boldak, which monitors the border crossing along with the Afghan Border Police and the Afghan National Army.
