The Afghanistan–Pakistan Transit Trade Agreement (APTTA) allows Afghan and Pakistani cargo trucks to transit goods within both nations. This revised US-sponsored APTTA agreement also allows Afghan trucks to transport exports to India via Pakistan up to the Wagah crossing point. There are at least nine main land ports around Afghanistan. They include Abu Nasar Farahi in Farah Province, Aqina in Faryab Province, Hairatan in Balkh Province, Islam Qala in Herat Province, Sher Khan Bandar in Kunduz Province, Torghundi in Herat Province, Torkham in Nangarhar Province, Spin Boldak in Kandahar Province, and Zaranj in Nimruz Province. Some of these ports are mismanaged due to political corruption, which sometimes result in huge financial losses to the traders and transport companies.
