Regionalisation of the Pakistan-Afghanistan Conflict

The conflict between Pakistan and Afghanistan, historically rooted in disputes over the Durand Line, cross-border militancy and mutual mistrust, is increasingly acquiring a wider geopolitical dimension. China's growing diplomatic, military and economic engagement with Pakistan, alongside India's renewed ties with Afghanistan, has brought the longstanding tensions between Islamabad and Kabul into the broader strategic rivalry between Beijing and New Delhi. Although neither China nor India created the conflict, both have significant interests in its outcome. Their involvement is reshaping regional calculations, complicating diplomatic efforts and raising the stakes of an already volatile relationship. China's Strategic and Economic Interests China's involvement is closely tied to its longstanding strategic partnership with Pakistan. As Pakistan's largest trading partner and a major defence supplier, Beijing has invested heavily in the country's economic development, particularly through the China-Pakistan Economic Corridor (CPEC), a flagship component of its Belt and Road Initiative. According to the Council on Foreign Relations, the corridor's highway and energy projects represent investments estimated at approximately $65 billion. Protecting these investments from militant attacks and regional instability remains a central Chinese concern. Afghanistan presents both a security challenge and an economic opportunity for Beijing. Militant organisations operating in the region threaten Chinese interests, while improved relations with Kabul could open new trade routes connecting South and Central Asia. China is particularly concerned about the Turkistan Islamic Party, which Beijing associates with separatist militancy in Xinjiang. Afghanistan's narrow Wakhan Corridor borders China's western region, reinforcing Beijing's concerns that militant groups could exploit Afghan territory to threaten Chinese security. Consequently, China has repeatedly sought assurances from the Taliban authorities that Afghanistan will not provide sanctuary to organisations threatening its interests. Economic considerations are equally important. In May 2025, China, Pakistan and Afghanistan agreed to cooperate on extending CPEC into Afghanistan, potentially improving regional trade and infrastructure connectivity. The three countries also discussed closer counterterrorism coordination. China's diplomatic involvement became particularly visible in April 2026, when representatives from Pakistan and Afghanistan attended talks in Urumqi from April 1 to 7 amid escalating tensions. The discussions brought together senior foreign affairs, defence and security officials. Afghanistan described the consultations as useful, while China indicated that both sides had agreed to explore comprehensive solutions and avoid further escalation. Pakistan used the talks to reiterate its security demands, including action against the Tehreek-e-Taliban Pakistan (TTP) and the dismantling of militant infrastructure allegedly operating from Afghan territory. Beijing's role demonstrated its emergence as more than an economic and military partner of Islamabad. It has also become an important diplomatic intermediary between Pakistan and Afghanistan. For China, continued hostilities threaten investments, regional connectivity, the security of Chinese nationals and prospects for expanding trade. Its interests therefore extend beyond Pakistan's immediate concerns about cross-border terrorism. India's Renewed Engagement with Afghanistan India, meanwhile, has gradually rebuilt its relationship with Afghanistan following the Taliban's return to power in August 2021. New Delhi initially closed its embassy in Kabul but subsequently adopted a cautious policy of engagement, establishing a technical mission in 2022 to coordinate humanitarian assistance and maintain diplomatic contacts. In January 2025, Taliban officials described India as a significant regional and economic partner. Relations advanced further in October 2025, when Afghan Foreign Minister Amir Khan Muttaqi visited New Delhi and India announced plans to restore its full diplomatic presence in Kabul. Despite this engagement, India has not formally recognised the Taliban government. India's interests in Afghanistan are both economic and strategic. New Delhi has invested more than $3 billion in Afghan development projects over the years, including healthcare, infrastructure and water management. It has also maintained humanitarian assistance while exploring trade opportunities through Iran's Chabahar Port, which provides access to Afghanistan without relying on Pakistani transit routes. For Islamabad, however, India's expanding engagement with Kabul raises longstanding security concerns. Analysts Feryaz Ocakli and Yelena Biberman, writing for the Lowy Institute, have highlighted Pakistan's apprehension that India could exploit deteriorating relations between Islamabad and Kabul to strengthen its influence along Pakistan's western frontier. India, for its part, sees engagement with Afghanistan as an opportunity to preserve its regional influence, protect economic interests and address potential security threats, including those involving militant organisations. Pakistan has accused India of supporting the TTP and has portrayed the Taliban administration as increasingly aligned with New Delhi. These allegations reflect Islamabad's longstanding concerns about strategic encirclement and the possibility of facing hostile pressures along both its eastern and western borders. However, India's growing diplomatic relationship with Kabul does not, in itself, establish Indian involvement in TTP attacks or military operations against Pakistan. Distinguishing between legitimate security concerns, political allegations and verifiable evidence remains essential. A Wider Regional Challenge The evolving regional alignments should not be mistaken for two equivalent alliances. China's relationship with Pakistan is longstanding, institutionalised and supported by extensive military, diplomatic and economic cooperation. India's relationship with Taliban-ruled Afghanistan, by contrast, remains relatively recent, cautious and largely pragmatic. Nevertheless, the growing involvement of both powers has introduced additional strategic considerations into the Pakistan-Afghanistan dispute. China seeks stability to protect its investments, contain militancy and expand regional connectivity. India wants to preserve its influence in Afghanistan, maintain access to Central Asia and prevent Pakistan from dominating Kabul's foreign relations. Pakistan remains primarily concerned about cross-border militancy, particularly attacks attributed to the TTP, while Afghanistan's Taliban authorities face their own political, economic and security pressures. The result is a conflict that can no longer be understood exclusively through the historical grievances between Islamabad and Kabul. Yet describing Afghanistan as merely another arena for China-India competition would oversimplify the situation. The fundamental disputes remain bilateral, even as wider geopolitical rivalries increasingly influence diplomatic choices. Ultimately, reducing tensions will require sustained engagement between Pakistan and Afghanistan, credible counterterrorism commitments and regional cooperation. China's mediation and India's diplomatic engagement could contribute to stability, provided their competing interests do not deepen existing divisions. The consequences of continued confrontation would extend well beyond the two neighbouring countries, affecting security, trade and economic connectivity across South and Central Asia.
