The United States stressed the importance of a revised transit agreement between Pakistan and Afghanistan to revitalize the trade route along the ancient Silk Road between South Asia, Central Asia and the Middle East.  Due to the inadequacies of ATTA, a new treaty between Afghanistan and Pakistan was needed, which allowed Afghanistan to access Indian markets and Pakistan to have reciprocal access to Central Asian markets via Afghanistan – much more stable until 2010 than in the last 20 years. Afghan trucks are to enter Pakistan through the Border Crossings of Torkham, Ghulam Khan and Shaman to transport Afghan goods through Pakistani territory and import goods from Pakistani ports of Karachi, Port Qasim and Gwadar.  The signed agreement allows Afghan trucks to access the Wagah border with India, where Afghan goods are unloaded on Indian trucks, but no Indian cargo can be loaded onto trucks transported to Afghanistan.  The Afghanistan-Pakistan Transit Trade Agreement (also known as APTTA) is a bilateral trade agreement signed by Pakistan and Afghanistan in 2010, which calls for greater facilitation of merchandise trade between the two countries. Implementation of the treaty has been inconsistent and both sides have complained about the persistence of trade barriers. The APTTA agreement allows Afghan trucks to transport exports to India to the Wagah crossing point via Pakistan, but does not offer Afghanistan the right to import Indian goods via Pakistani territory, lest Indian goods end up on the Pakistani black market, as was the case in 1965 under the ATTA. Instead, Afghan trucks dumped in Wagah can return to Afghanistan, which are loaded only with Pakistani goods instead of Indian goods to prevent the creation of a black market for Indian goods in Pakistan. While Afghan importers and exporters enjoy unrestricted access to Pakistani seaports under APTTA, Afghanistan has claimed that Pakistani officials often block deliveries and cause unnecessary delays, especially after the NATO attack on Pakistan in 2011. In November 2010, the two states formed a joint chamber of commerce to develop their trade relations and resolve the problems faced by distributors, both in this and other respects.   ATTA has not granted reciprocal rights to Pakistan to export goods through Afghan territory to neighbouring countries. Pakistani attempts to access Central Asian markers have been thwarted by political instability in Afghanistan that has continued since the late 1970s. As Afghanistan became increasingly dangerous as a transit corridor, China, Pakistan, Kazakhstan and Kyrgyzstan developed a separate contract in 1995 called the Quadrilateral Traffic in Transit Agreement (QTTA) and signed the treaty in 2004.
 Despite the signing of the QTTA, the agreements were never used, mainly due to poor infrastructure between the four countries.
