In July 2012, Afghanistan and Pakistan agreed to extend AptTA to Tajikistan, which will be the first step towards the creation of a North-South trade corridor. The proposed agreement will provide Tajikistan with the opportunity to use Pakistani ports and the Wagah border for imports and exports, while Pakistan would obtain tariffs for the transit of goods via Tajik territories to Kyrgyzstan and Uzbekistan.  The 2010 agreement replaces the 1965 Afghanistan transit agreement, which granted Afghanistan the right to import duty-free goods through Pakistani seaports, particularly Karachi.  The 1965 agreement did not see Pakistan as the right to export goods to the Soviet Union or the Central Asian republics after the fall of the USSR, nor did it see the right to export goods.  Afghanistan also refuses to grant Pakistan the right to import and export goods from Central Asia via Afghan territory. The 2010 APTTA agreement allowed Afghan goods to be exported to India via Pakistani territory, but did not authorize the export of Indian goods to Afghanistan via Pakistani territory.  In October 2010, the pioneering APTTA agreement was signed by Pakistani Trade Minister Makhdoom Amin Fahim and Anwar ul-Haq Ahady, the Afghan Ministry of Commerce. Richard Holbrooke, U.S. Special Representative for Afghanistan and Pakistan, as well as a number of foreign ambassadors, Afghan parliamentarians and senior officials attended the ceremony.  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.
