Why the Durand Line Matters: Towards a De-Escalation Between Afghanistan and Pakistan?

Diplomacy of the Durand Line between Afghanistan and Pakistan_SpecialEurasia

Executive Summary

On 7 March 2026, the Taliban Defence Minister, during a Pashto-language engagement with ToloNews, identified the Durand Line as a primary friction point in Afghan-Pakistani relations.

The Minister acknowledged a formal Pakistani proposal for the definitive recognition of the Line as an international border.

Given the protracted territorial dispute and escalating frontier skirmishes, this report evaluates whether a diplomatic resolution would mitigate regional volatility or inadvertently catalyse local insurgencies by further fragmenting the Pashtun ethnic core.

Key Points

  1. The Durand Line remains one of South Asia’s most enduring territorial disputes; its legal ambiguity serves as a significant strategic lever for Kabul against Islamabad.
  2. The creation of an official border between Pakistan and Afghanistan may successfully represent a milestone in a de-escalation policy for both countries.
  3. Pashtun populations risk another fragmentation of their tribal customs and the end of their ‘Pashtunistan’ nationalist project.

Background Information

On 7 March 2026, Mawlawi Mohammad Yaqoob, the Minister of Defence of the Islamic Emirate of Afghanistan, accentuated how the Durand Line still represents a major element of tension between Afghanistan and Pakistan. He further emphasised Pakistan’s worries about this matter and admitted that Islamabad had proposed to officially recognise the Durand Line as the international boundary between the two nations.

The de facto border that separates Afghanistan and Pakistan is the heritage of British colonialism in South Asia. More specifically, it marks the moment when the Afghan sovereign Amir Rahman Khan granted Afghan foreign policy to the British government. With the aim of isolating and weakening Pashtun tribes between Afghanistan and British India, the boundary was established following earlier defeats of the British army by these communities. The establishment of this border served to protect Britain’s security.

The creation of Pakistan and Afghanistan further intensified the issue, since both countries could never acknowledge the line as their official border. As a result, both nations have used the legal uncertainty to exert influence over one another. No Pakistani or Afghan administration has reached a lasting resolution to the issue, generating persistent underlying tensions that have periodically escalated into open hostilities, like the clashes that occurred in September 2022.

Additionally, the boundary’s establishment diminished Pashtun national aspirations for ‘Pashtunistan,’ a nation founded on ‘Pashtunwali,’ the Pashtun code of honour that shapes the daily lives of their tribes.

Previously, Afghanistan leveraged nationalistic sentiments to exert pressure on its neighbour, Pakistan. Conversely, Pakistan started supporting radical Islamic Pashtun individuals to further its geopolitical objectives concerning Afghanistan and India. In the 1990s, following the Soviet-Afghan War (1979-1989), this situation led to the emergence of the Taliban and other significant regional jihadist organisations, making the area a key hub of instability in South Asia.

Analysis

The Path to Stabilisation

Formal border recognition would represent a definitive shift toward regional stabilisation, provided robust intelligence-sharing and mutual trust underpin it. A settled border would enhance frontier security protocols and regularise diplomatic channels. Furthermore, a stabilised ‘Western Front’ could incentivise expanded Chinese strategic investment, building upon the diplomatic initiatives of August 2025. This ‘securitisation’ could pivot China from a purely economic actor to a regional security guarantor.

Taliban Strategic Dilemma

The de facto Taliban administration faces a complex ‘security-legitimacy’ trade-off. Engaging in formal border negotiations allows the movement to project the image of a responsible sovereign actor to the international community. However, if the central authority manages the transition poorly, it may disrupt the fragile internal equilibrium with affiliated militant groups. A perceived ‘sell-out’ on the Durand Line could trigger defections to the Islamic State Wilayat Khorasan (ISKP), which is already aggressively expanding its Pashto-language propaganda.

Pakistan’s Strategic Calculus

For Islamabad, border recognition provides a potential ‘off-ramp’ from its domestic security crisis. Amidst high internal volatility, securing the western frontier would allow the Pakistan Armed Forces to reallocate resources. This objective aligns with Pakistan’s broader desire to improve its international standing, following its recent participation in the Trump-led ‘Board of Peace’ for Gazan reconstruction.

Operational Risks: The Pashtun Factor

Eliminating border porosity risks a backlash that results in a ‘hard border’. The disruption of cross-border tribal lineages may reinvigorate Pashtun ethno-nationalism, creating a fertile recruitment ground for anti-state actors. For the Taliban, endorsing a colonial-era border threatens their ideological purity and could deepen factional rifts between ‘pragmatists’ and ‘hardliners.’

Conclusion

The fighting that occurred on the frontier from October to November 2025, followed by open hostilities in February 2026, has brought the Durand Line dispute back to prominence. Far from being isolated episodes, these incidents reflect a persistent source of instability for both Pakistan and Afghanistan.

For this reason, advancing diplomatic initiatives aimed at rebuilding a basic level of mutual trust and addressing this shared vulnerability appear essential. For both Kabul and Islamabad, therefore, the question of the Durand Line remains not only a territorial dispute but also a delicate political and security dilemma.

Another important and common element is the cultural importance of this frontier region. Thus, any sustainable solution will require a careful balance between state interests, regional security considerations, and the complex social dynamics of the Pashtun borderlands.
