Background and Names:
The Afghanistan–Pakistan Transit Trade Agreement (also known as APTTA) is a bilateral trade agreement signed in 2010 by Pakistan and Afghanistan that calls for greater facilitation in the movement of goods amongst the two countries. In October 2010, the landmark APTTA agreement was signed by Pakistani Commerce Minister Makhdoom Amin Fahim and Anwar ul-Haq Ahady, Afghan Ministry of Commerce. The ceremony was attended by Richard Holbrooke, US Special Representative for Afghanistan and Pakistan, and a number of foreign ambassadors, Afghan parliamentarians and senior officials. On 23 October 2017, the President of Afghanistan Ashraf Ghani announced that "The Afghanistan and Pakistan Trade Agreement (APTA) has expired"and issued a decree banning Pakistani trucks from entering the country via the Torkham and Spin Boldak border crossings. 
The bilateral agreements between Pakistan and Afghanistan, but so far, have failed to make exporting more reliable and efficient. These include the Afghanistan-Pakistan Transit Trade Agreement (APTTA) which aims to “facilitate the uninterrupted flow of transit trade between the two countries” as well as bilateral accords reached in the Pakistan-Afghanistan Trade and Investment Forum which was held during the two-day visit of Pakistan’s Prime Minister, Imran Khan to Kabul in January 2021.
 

In Kandahar, many were hopeful that the takeover of the Taleban, a close ally of Pakistan, would herald a new era of genial relations between Kabul and Islamabad and bring unremitting closures at Spin Boldak to an end. Those who had managed to bring in a harvest, despite the fighting and drought, were optimistic that they would be able to get their produce to market in Pakistan and beyond. Their hopes soon faded and optimism gave way to frustration as the gate remained largely closed for several months. When it finally did open on 2 November 2021, it was too late to save most of the harvest. The extended closure also led to clashes, as the thousands of Afghans trapped behind closed gates began to protest, demanding Pakistan and the Taleban re-open the gate.
 

Pakistan closed the Spin Boldak gate again on 24 February 2022 after clashes erupted between the Pakistani and Taleban forces at the border, following Pakistani attempts to repair a damaged fence along the Durand Line. Both sides blamed each other for starting the clashes that later spread to several nearby villages. Two civilians were killed and 22 wounded on [the] Afghan side, a local Taleban spokesman Mohammad Asif Hakimi said. Five Taleban soldiers were also wounded…. Pakistani officials said several wounded includ[ing] four security officials. According to reports from Kandahar, the crossing was reopened after the Nawruz holiday (21 March 2022) to trade traffic, with the two countries agreeing on temporary licences for lorry drivers to facilitate the transit of goods.
