The conflict between Pakistan and Afghanistan is one of the most complex geopolitical challenges in modern South Asia, rooted in historical border disputes and present-day security fears. When Taliban 2.0 took over Kabul in 2021, it was expected that Pak-Afghan relations would strengthen; instead, their political relationship has reached a dangerous boiling point in early 2026. What is at stake is not just the safety of the people living along the Durand Line, but also the economic future of an entire region desperate to connect landlocked Central Asian countries to Pakistani ports and South Asian markets.
The early months of 2026 saw a dramatic shift from traditional border skirmishes to deep, devastating military strikes. On February 22, Pakistani air strikes inside Afghanistan resulted in the deaths of 20 civilians. This set off a rapid chain of retaliation. Afghan forces attacked Pakistani military bases on February 26, which Islamabad answered with another round of strikes the following day.
The violence peaked on March 17, when an attack on a drug rehabilitation center in Kabul resulted in over 400 reported deaths. While Pakistan argues these actions are necessary to dismantle terrorist hideouts, Kabul maintains these are direct attacks on its citizens and sovereign land. The human cost is staggering, with over 100,000 Afghans and thousands of Pakistanis displaced from their homes in a matter of weeks.
Currently, a fragile truce is in place to observe Eid al-Fitr. Mediated by Turkey, Qatar, and Saudi Arabia, this pause has offered families a brief moment of peace. However, this calm is temporary; it provides ‘breathing room’ but does not resolve the core grievances that fuel the fire.
How will it impact the Regional Connectivity?
Central Asian countries are landlocked (Uzbekistan is doubly landlocked) and have been exploring the possibility of connecting to warm waters via both Iran and Afghanistan. These countries were very interested in India-led connectivity projects such as the International North-South Transport Corridor (INSTC) and the Chabahar port. However, due to sanctions on Iran and many other issues, these projects have been delayed or have not reached to their full potential. In this scenario, the Central Asian countries looked towards Pakistan to reach their ports via Afghanistan. It's not just the physical connectivity; projects related to natural gas and hydroelectricity between South and Central Asia are also underway.
Beyond the immediate tragedy of war, this conflict threatens to derail the abovementioned ambitious infrastructure projects that could transform the regional economy. Afghanistan sits at the center of a natural corridor for trade and energy for Central Asia, but that corridor is currently blocked. The recent conflict between Pakistan and Afghanistan has raised serious doubts about the future of these initiatives, which are still in the inception phase.
The Trans-Afghan Railway
One of the most ambitious projects is the Trans-Afghan Railway, designed to link the landlocked states of Central Asia, specifically Uzbekistan, to the warm-water ports of Pakistan, like Karachi and Gwadar. This idea was proposed by Uzbek president Shawkat Mirziyoyev in December 2018 to expand the already operational Termez-Mazar-i-Sharif railway line further to Kabul and down to the Pakistani rail network. In early 2026, Uzbekistan, Afghanistan, and Pakistan signed agreements for technical cooperation and a feasibility study. Uzbekistan also approved an intergovernmental agreement to advance feasibility studies, specifically focusing on segments such as Naibabad to Kharlachi.
However, there have been many structural issues with this project. Funding is the main issue. The estimated cost is around USD 7 billion, which none of the parties can afford. Interestingly, Kazakhstan came forward and offered to bear the cost of the projects, a move that remains doubtful. Despite some technical progress and discussions on track gauges (1520 mm), actual construction remains stuck. Insecurity at the Torkham border crossing has shattered investor confidence and disrupted the logistics needed to move from planning to real-time construction.
The TAPI Gas Pipeline
The Turkmenistan-Afghanistan-Pakistan-India (TAPI) pipeline is a multi-billion-dollar project intended to transport natural gas from Turkmenistan's Galkynysh field. Conceived in the 1990s, a pipeline stretching 816 km across Afghanistan, providing the country with much-needed transit fees and a steady gas supply while fueling the industrial needs of Pakistan and India. Due to tensions between India and Pakistan, this project has been in the pipeline for decades.Though the Turkmenistan government has claimed that it has completed construction of the pipeline, it remains suspicious about its progress. According to Afghan sources, surveying is mostly complete for the route to Herat, and about 91 km of the route has been prepared for installation. The ongoing border conflict has made the project a high-risk gamble. Insurance costs have skyrocketed, and the physical delivery of pipes and machinery is frequently delayed by border closures.
CASA-1000: Powering the Future
The Central Asia-South Asia (CASA-1000) project is perhaps the closest to completion, aimed at bringing surplus hydropower from Kyrgyzstan and Tajikistan to Pakistan. It involves 1,200 km of high-voltage lines and converter stations. While work in the northern nations is nearly finished, the 575 km stretch through Afghanistan has been a major bottleneck. Work restarted in late 2024 with international support. By early 2026, new towers were being erected and foundations laid. If completed by the 2027 target, it would provide Pakistan with affordable, clean energy. However, the current violence makes it incredibly difficult for contractors to work safely on the ground, and if the issue persists in the long term, Kabul might not allow the energy to pass through its territory to Pakistan.
The Economic Toll of a Closed Border
When the political temperature rises, the borders often close. For the people living in these regions, this is an economic catastrophe. During periods of high tension, bilateral trade volumes through crossings like Torkham and Spin Boldak often drop by 30-40%. Every day a truck sits idling at a closed border, the cost of trucking, insurance, and security goes up. This eventually leads to higher prices for consumers on both sides. Beyond commercial goods, border restrictions slow down the delivery of life-saving aid to displaced populations. This does not necessarily limit to those countries that are fighting, but also to other regional countries that are not directly involved but have strategic or economic interests.
The reason these projects remain in limbo is the fundamental disagreement between the two governments. Islamabad demands firm action against the Pakistani Taliban (TTP), which it claims uses Afghan soil as a safe haven to launch attacks inside Pakistan. The government in Kabul emphasises its national sovereignty and refuses to recognise the Durand Line as a legitimate international border, viewing it instead as a colonial imposition. However, the reasons for the justification may differ. Pakistan has serious issues with India’s increasing presence in Afghanistan. There have been many visits by Taliban ministers to New Delhi, which might have caused concern for Islamabad. To sabotage this, they reportedly started the conflict. External players like China, Turkey, and Qatar continue to push for dialogue, recognising that a stable Afghanistan is the only way the Belt and Road Initiative and other regional visions can succeed.
Conclusion
For the truck drivers at the border, the farmers in Tajikistan, and the traders in Uzbekistan, the benefits of cooperation are not abstract concepts; they are a matter of survival. When border’s function, prices stabilise, and jobs are created. When they fail, everyone pays. The ‘Eid pause’ of 2026 proves that a ceasefire is possible. However, turning that pause into lasting peace requires more than a holiday agreement. It requires a mutual commitment to prioritise shared economic survival over historical grievances. If the region can find a way to manage its borders together, these connectivity projects could finally move from the drawing board to reality, benefiting millions of lives. If not, the region will remain divided, missing out on the immense opportunities that a connected Asia could provide.
