A Fragile Relationship Defined by Geography and History
The Pakistan-Afghanistan relationship has always been influenced by deep-rooted historical, cultural, and ethnic linkages. Sharing a 2,640-kilometre border known as the Durand Line, both countries are bound by geography and intertwined tribal dynamics. However, this very border has become a flashpoint for conflict, largely due to its porous nature and the lack of effective governance on either side. For decades, Afghanistan has accused Pakistan of harbouring militants, while Pakistan blames Afghanistan for allowing its soil to be used for attacks across the border. These accusations have created a vicious cycle of distrust that continues to weaken cooperation and regional peace efforts.
The Legacy of Conflict and the Rise of Militancys
The Afghan conflict, beginning with the Soviet invasion in 1979 and continuing through the US-led war on terror, has left a power vacuum that multiple militant groups have exploited. The Tehrik-i-Taliban Pakistan (TTP), Islamic State Khorasan Province (ISKP), and other non-state actors have used Afghan territory to regroup and launch attacks into Pakistan. Simultaneously, the Afghan Taliban has often found sanctuary within certain pockets of Pakistan’s tribal areas. This reciprocal militancy has caused tremendous civilian and military casualties, undermined border security, and led to accusations of proxy warfare. As a result, both governments have grown increasingly suspicious of each other’s intentions, further eroding trust.
The Refugee Burden and Its Political Implications
One of the most enduring legacies of the Afghan conflict has been the large-scale displacement of people. At the peak of the Afghan wars, over three million Afghan refugees crossed into Pakistan, making it one of the largest refugee-hosting nations in the world. Even today, more than a million Afghan refugees remain in Pakistan, some registered but many undocumented. While these refugees have found shelter, their prolonged stay has created serious socio-economic and security concerns for Pakistan. Allegations of militants blending in with refugee populations have intensified calls for stricter border controls and repatriation drives. However, such moves often strain bilateral relations, especially when carried out unilaterally or without diplomatic consultation.
Militancy’s Impact on Border Management and Trade
In recent years, Pakistan has intensified efforts to fence the entire Durand Line in response to cross-border attacks. While Pakistan considers this a legitimate security measure, Afghanistan has protested the fencing, refusing to recognize the Durand Line as an official border. The militarization of the border has significantly hampered legal cross-border trade, disrupted traditional tribal linkages, and increased tensions between the two countries. Furthermore, frequent border closures due to militant threats have crippled the livelihoods of traders and locals who depend on the movement of goods and people. Consequently, what was once a soft border rooted in shared tribal heritage has become an arena of military posturing.
Diplomatic Fallout and Regional Isolation
Cross-border militancy and refugee movements have also affected Pakistan and Afghanistan’s regional standing. Both nations have faced criticism from international partners for not doing enough to curb terrorism. The failure to coordinate on counterterrorism has cost both countries foreign aid, investment, and strategic alliances. For instance, peace talks involving the Taliban and the United States often sidelined the Afghan government, undermining its legitimacy. Similarly, Pakistan’s perceived support for certain militant factions has drawn condemnation from global watchdogs. The bilateral inability to present a united front against militancy has made both states vulnerable to international pressure and regional isolation.
Enhancing Border Security Cooperation
One of the most viable solutions is the institutionalization of joint border security mechanisms. Both nations must move beyond unilateral measures and engage in coordinated intelligence sharing, joint patrols, and border management strategies. Establishing a bilateral security commission under the supervision of neutral international observers could help reduce suspicion and ensure accountability. Moreover, transparent communication can address false flag operations or misinterpretation of militant activities as state-sponsored aggression. A secure and well-managed border would diminish the operating space for militant groups and reduce illegal crossings.
Developing a Humane Refugee Policy
Addressing the refugee issue requires balancing security concerns with humanitarian obligations. Pakistan and Afghanistan, with the assistance of international organizations such as UNHCR, should work together on a phased and dignified repatriation plan. Simultaneously, registered refugees must be provided access to education, employment, and healthcare to reduce their marginalization. It is also essential to crack down on criminal networks that exploit refugee settlements for illicit purposes. Creating refugee townships closer to the Afghan side of the border, jointly administered by both governments, may serve as a transitional solution.
Promoting Cross-Border Economic Zones
Economic interdependence can play a crucial role in reducing tensions. The establishment of cross-border economic zones can revitalize trade and create employment opportunities for border communities. Projects such as roads, rail links, and marketplaces should be jointly funded and managed. When economic incentives are tied to peace and stability, communities become less susceptible to militant recruitment. Furthermore, economic cooperation would foster intergovernmental dialogue and help rebuild trust. Trade diplomacy, if pursued sincerely, can pave the way for political reconciliation.
Fostering Regional Dialogues and Mediation
Multilateral platforms such as the Shanghai Cooperation Organization (SCO), SAARC, or even trilateral dialogues involving China, Pakistan, and Afghanistan can be used to mediate tensions. A neutral third-party mediator can help both sides move past historical grievances and focus on practical solutions. Peace in the region requires not just bilateral understanding but regional coordination. As both countries are strategically important to China’s Belt and Road Initiative, leveraging mutual interests through regional frameworks can offer a diplomatic way forward.
Investing in Counter-Narratives and Community Engagement
Both governments need to invest in countering extremist ideologies that fuel cross-border militancy. This requires coordinated efforts in community outreach, religious education reforms, and the promotion of inclusive national identities. Joint cultural programs, media exchanges, and civil society collaborations can also help bridge divides. Counterterrorism cannot be limited to military responses; it must also address the ideological roots of extremism. Empowering local leaders and tribal elders through peace-building initiatives can bring grassroots stability and discourage militant sanctuaries.

Although both Pakistan and Afghanistan have legitimate grievances, their policies often reflect reactionary postures rather than strategic vision. Pakistan's security-centric approach and Afghanistan's political instability hinder long-term collaboration. Moreover, the mistrust is amplified by non-state actors and geopolitical players who benefit from the continued tension. Without a shift in mindset from blame to cooperation, even the most viable solutions may fail to gain traction. Nevertheless, mutual dependence for peace and prosperity necessitates that both nations prioritize dialogue, compromise, and coordinated action over unilateral assertions and rhetorical hostility.
In conclusion, cross-border militancy and refugee movements have significantly strained Pakistan-Afghanistan relations, fueling mistrust, economic setbacks, and diplomatic isolation. However, these challenges are not insurmountable. Through coordinated border management, humane refugee policies, economic collaboration, regional diplomacy, and ideological reform, both nations can pave the path toward a more stable and cooperative future. The key lies in recognizing shared vulnerabilities and converting them into opportunities for peacebuilding and regional integration. Only sustained engagement and mutual accountability can ensure that these issues do not continue to define their bilateral relationship.
