Afghanistan's tensions with Pakistan are accelerating engagement between Kabul and other regional states, but the benefits from expanded ties will remain limited by enduring disputes, logistical constraints, security threats to major infrastructure projects and Islamabad's potential absence from future multilateral engagements. Recent deadly militant attacks in northwest Pakistan — including one on May 9 that targeted police personnel and one on May 12 that targeted a local market — exacerbated tensions along the Afghanistan-Pakistan border months after the neighbors' current conflict over alleged cross-border militancy erupted on Feb. 21. Clashes have eased since the conflict's early weeks, when Pakistan's air force struck various Afghan cities for days, but sporadic clashes and periodic flare-ups — like that reported on May 4, when the Afghan Taliban accused Pakistan of striking two schools, two mosques and a health center — have continued. While the most direct consequences of these clashes have been cross-border firefights, shellings and other kinetic strikes, a lower-profile and potentially more enduring consequence has been the effective rupture of ties between Kabul and Islamabad. This rupture followed years of Pakistani support for the Afghan Taliban during the 2001-2021 U.S. war in Afghanistan, as well as continued backing since then, with Islamabad until recently remaining Afghanistan's largest trading partner and a steadfast source of humanitarian aid. In exchange, Pakistan expected to retain influence over the group to ensure its own interests, which include limiting India's influence in Afghanistan, reducing the threat the Afghan Taliban posed to Pakistan and cracking down on Afghanistan-based anti-Pakistan militants. However, since coming to power in 2021, the Afghan Taliban has instead prioritized its independence, Afghan nationalism and ties to long-standing militant partner Tehrik-i-Taliban Pakistan, or TTP. This pattern, alongside Pakistan's late-February characterization of its clashes with Afghanistan as an "open war," underscores the extent to which the neighbors' ties have fractured. In response, Afghanistan has prioritized bolstering its other regional partnerships.

• TTP originated in northwest Pakistan and provided aid to the Afghan Taliban during the latter portion of the U.S. war in Afghanistan. This has rendered more senior and typically hard-line Afghan Taliban officials particularly reluctant to betray TTP, especially to Pakistan, with which the Afghan Taliban retains long-standing disputes, like that over the legitimacy of their shared border.
• Afghanistan and Pakistan's latest rounds of conflict have been their most enduring and severe since the Afghan Taliban retook Afghanistan in August 2021. The second-most recent bout erupted in October 2025, when Pakistan's military struck Kabul in a reported attempt to kill top TTP figures, including the group's leader, Noor Wali Mehsud. The strikes allegedly failed to kill Mehsud and kicked off additional attacks in subsequent days, including Afghan Taliban retaliatory assaults on Pakistani military positions along the countries' border, as well as Pakistani strikes on Afghanistan's Kandahar and Helmand provinces, before ending in a ceasefire. 
• Aside from the unprecedented harsh rhetoric, the ongoing bout of clashes represents a tactical escalation, with Pakistan conducting even more enduring and frequent kinetic strikes on a wider range of Afghan cities. Afghanistan has also launched unmanned aerial vehicles into Pakistan that have reached as far as Islamabad's outskirts. Both rounds of conflict have been far more escalatory than the sporadic border clashes and one-off airstrikes targeting alleged Afghanistan-based anti-Pakistan militants that Pakistan's military had executed in prior years.

The collapse in Afghan-Pakistani ties breaks from a trend in which regional countries have, to varying extents, increasingly engaged with Afghanistan's hard-line rulers. Since the Afghan Taliban returned to power in August 2021, neighboring countries have remained concerned about Afghanistan's hard-line rulers and their willingness to host militants that threaten regional security. Even so, most neighboring governments have pragmatically engaged with Kabul to secure their respective interests, even as the West has been slower to do so. Uzbekistan, Turkmenistan, Kazakhstan, China, Iran and Russia were among the earliest to diplomatically engage with the Afghan Taliban, including through regular diplomatic communications and in-person meetings. These countries were motivated by interests like security and resource sharing, with some, particularly China, even probing prospects early on for their companies to undertake infrastructure projects and resource extraction in Afghanistan. The most striking illustration of regional countries' commitment to working with Afghanistan has been Uzbekistan's, Iran's and Russia's decisions to bolster their ties and security cooperation with the Afghan Taliban following militant attacks attributed to the Afghanistan-based Islamic State Khorasan Province. Iran's and Russia's decisions to do so were particularly notable, given the high-profile and deadly nature of the attacks they sustained, with militants killing more than 100 people and wounding some 284 others at a January 2024 event in Kerman, Iran, and killing 151 people and injuring more than 600 others in March 2024 at a music venue in Moscow, Russia. Eventually, in July 2025, Russia even became the first country to formally recognize the Afghan Taliban diplomatically. 

• Russia's diplomatic recognition of the Afghan Taliban broke a yearslong taboo, ostensibly easing constraints on other regional countries' willingness to undertake similar efforts, particularly to bolster ties with Afghanistan. However, regional countries have thus far avoided doing so and instead continue to bolster ties with Afghanistan in practice, potentially due to concerns about censure or other costs to their international ties. For instance, China has been among the most active in fostering ties with the Afghan Taliban, but Chinese officials have previously suggested Beijing is in no rush to recognize the group and would be more likely to do so should more of the international community move in that direction.

The effective collapse of Afghanistan and Pakistan's long-standing partnership in 2025, and particularly Pakistan's indefinite suspension of their bilateral trade, has accelerated the expansion of ties between Afghanistan and its non-Pakistani neighbors. During their prior round of cross-border clashes in October 2025, Pakistan indefinitely suspended cross-border trade with Afghanistan, severing Kabul from what had been its largest trading partner. While the cessation of their bilateral trade has undoubtedly challenged Afghanistan's already beleaguered economy, the development also provided Afghanistan and regional countries — even those that had long resisted fostering relations with the Afghan Taliban, like India — an opportunity to expand bilateral engagement. By November 2025, Afghan officials announced they had begun "actively working with [their] northern neighbors to find reliable trade alternatives" to Pakistan, which they accused of using trade as a "tool of political pressure." Months later, in February 2026, diplomats from Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan met to develop a joint diplomatic approach to Afghanistan, underscoring Central Asia's openness to expanding ties with the country; one attendee reportedly characterized expanding trade ties with Afghanistan as "critically important" for Central Asia. These developments culminated in Kabul hosting the inaugural Afghanistan-Central Asia Consultative Dialogue in April 2026, when high-ranking officials from all five Central Asian countries assembled in Afghanistan for the first time since the Afghan Taliban's return to power. Introducing the meeting, Afghanistan's foreign minister referenced data collected by Afghan authorities reportedly indicating Afghan trade with Central Asia had risen from $1.8 billion in 2024 to $2.6 billion in 2025, among the most substantial year-on-year increases in their trade since 2021. Afghanistan's foreign minister added that Kabul would work to further increase trade with Central Asian countries to $10 billion over the next three to four years — figures that are likely aspirational but underscore Afghanistan's intention to diversify its ties beyond Pakistan. 

• India stepped up its engagement with Afghanistan as early as January 2025, when senior Indian and Afghan foreign ministry officials met in Dubai for the two sides' highest-level meeting since the Afghan Taliban returned to power. This engagement accelerated later that year, possibly in response to India's cross-border clashes with Pakistan in May, as well as to undermine the influence of another regional rival, China, in Afghanistan. Against this backdrop, New Delhi hosted the Afghan Taliban's top diplomat for the first time in October 2025, and it was one of the first regional governments to send humanitarian aid to Afghanistan in November 2025 following a deadly earthquake in the country's north — a move Indian officials subsequently touted as demonstrating India's role as a "first responder."
• Tajikistan's participation in the April 2026 talks in Kabul was especially notable, as its opposition to the Afghan Taliban had been particularly strong, leading it to hold out longer than its other Central Asian neighbors against meaningful engagement with the group. In the 1990s and early 2000s, Tajikistan actively supported anti-Taliban resistance forces, and it reportedly hosted anti-Taliban figures after the group retook Afghanistan in August 2021. However, its stance toward Afghanistan began to ease in 2025, especially in the second half of the year, when Tajik and Afghan officials undertook several reciprocal visits to discuss issues ranging from security to potential joint economic projects.

Despite Afghanistan's expanding ties with its neighbors, these relationships are poised to remain pragmatic and constrained by periodic tensions and logistical challenges, limiting potential benefits. While Afghanistan's neighbors are showing a new willingness to engage with the Taliban, these relationships will likely remain strictly pragmatic and constrained by enduring mistrust of the group's hard-line stance and militant links. These ties will thus remain vulnerable to shocks, ranging from diplomatic tensions and punitive measures to border clashes, which may lead more anxious governments to temporarily withdraw engagement. China, for example, remains highly apprehensive of the reported presence of the Uyghur militant Turkistan Islamic Party in Afghanistan, and of Afghanistan-based militants attacking Chinese nationals and investment projects in Pakistan. India has similar reasons to remain cautious, given the Afghan Taliban's enduring ties to al Qaeda and the smuggling of weapons from Afghanistan to militants in Kashmir. Afghanistan-Iran ties will also endure tensions, fueled by long-standing disputes over water resources from the Helmand and Hari rivers, as well as Iran's treatment and deportation of Afghan migrants. Additionally, Tajikistan's historical opposition to the Afghan Taliban, combined with recent incidents of criminal and militant violence along the Tajik-Afghan border, suggests bilateral relations will remain especially limited. More broadly, Afghanistan's regional integration through rail and energy infrastructure will also be hindered by its limited financial resources, challenging geography and the difficulty of securing projects in rural areas, which will likely further limit bilateral trade volumes and the overall expansion of regional ties.

Afghan-Pakistani tensions over cross-border militancy are unlikely to ease anytime soon, which will further limit the extent to which regional countries and Afghanistan benefit from expanded ties, such as through major transnational infrastructure projects. Afghanistan and Pakistan's relationship has in recent years endured repeated bouts of tension and prolonged periods of non-contact. However, the duration and severity of their current conflict — combined with Afghanistan's ongoing efforts to diversify away from Pakistan — suggest that, at a minimum, mending bilateral relations will take longer this time around. This would especially be the case if the recent border clashes unify the Afghan Taliban around the group's hard-line leadership, support for TTP and opposition to Pakistan, as some local reports suggest. Even if the Afghan Taliban did crack down on TTP in Afghanistan, it may not significantly reduce militant attacks in Pakistan, as TTP has for years rebuilt its presence in the country's northwest. Additionally, Baloch separatists, Islamic State fighters and other capable militants will also continue their own attacks. Given the myriad unresolved disputes between Afghanistan and Pakistan, including over the legitimacy of their shared border, the two neighbors are highly likely to again butt heads in the future. This will further limit the potential benefits of Afghanistan's expanding regional ties, particularly regarding ambitious infrastructure projects like the Turkmenistan-Afghanistan-Pakistan-India Pipeline, as getting these countries (especially the last three) to cooperate on such a massive project currently appears impossible. Additionally, each country would need to secure the massive associated infrastructure, posing yet another Sisyphean task, especially for countries like Afghanistan and Pakistan, which face perennial insurgency and terrorism challenges. Similar challenges will also threaten the proposed Uzbekistan-Afghanistan-Pakistan Railway Project, which, in its current form, would connect Uzbekistan's Tashkent to Afghanistan's Kabul and ultimately to Pakistan's Peshawar. 

• Years-long delays, largely fueled by regional conflict and militancy, have stalled progress on the Turkmenistan-Afghanistan-Pakistan-India Pipeline, the Uzbekistan-Afghanistan-Pakistan Railway Project, and other similar projects. While this has not directly worsened living conditions in host countries, it has put an upper limit on their energy supplies and power reliability, trade and broader economic growth. The perceived importance of these transnational infrastructure projects has almost certainly grown alongside various regional crises over the years, and particularly since the outbreak of the 2026 Iran conflict, as these crises have worsened inflation and risks of energy shortages and food insecurity.
