Afghanistan’s conflict with Pakistan on China’s doorstep challenges the premise behind one of the world’s largest geopolitical projects.
The outbreak of open hostilities between Pakistan and Afghanistan marks the most intense confrontation between the two neighbors since the Taliban returned to power in 2021. After weeks of cross-border clashes and retaliatory attacks, Islamabad declared a state of emergency. “Open War” and the Taliban government following airstrikes in areas targeting Afghan cities and border regions.
The violence shattered a ceasefire established in October 2025 and quickly became the worst situation along the 2,600km Durand Line in years. Tens of thousands of citizens have fled their homes, and the risk of a major regional crisis is increasing.
The immediate trigger lies in disputes over cross-border militancy. Pakistan accuses Kabul of harboring militants from the Tehreek-e-Taliban Pakistan (TTP), a claim the Taliban denies. Yet the geographic implications of this conflict extend beyond borders. For China, the war represents not only a security crisis but a direct challenge to its broader strategic vision of regional cooperation.
Among external stakeholders, China stands to lose the most from the long-standing rift between Islamabad and Kabul.
Over the years, Beijing has tried to position Pakistan and Afghanistan as key points in the regional economic architecture linking Central Asia, South Asia, and western China. At the center of this vision is the China-Pakistan Economic Corridor (CPEC), one of the flagship projects of the Belt and Road Initiative (BRI). Built around transport infrastructure, energy investments, and industrial zones stretching from China’s Xinjiang province to Pakistan’s Arabian Sea port of Gwadar, CPEC was conceived not only as a bilateral economic partnership but as the backbone of broader regional connectivity.
In Chinese strategic thinking, Afghanistan was intended to be a peripheral extension of this network. Beijing has explored connecting Afghanistan’s transportation routes, mineral resources, and transit routes to the broader CPEC infrastructure system. Such a partnership would give landlocked Afghanistan access to maritime trade while connecting Central Asian markets more closely with China’s western regions.
So the war between Pakistan and Afghanistan strikes directly at the geographical base of this economic compass.
China’s relationship with both countries underscores why the engagement is so important. Pakistan has long been China “all-weather strategic partnership partner.” The relationship covers defense cooperation, transfer of military technology and deep economic ties. China is Pakistan’s largest trading partner and the main investor behind CPEC projects, from highways and railways to power plants and special economic zones. Chinese companies have given tens of billions of dollars to Pakistan’s infrastructure, while Beijing sees the country as an important gateway connecting western China to the Indian Ocean.
China’s cooperation with Afghanistan, although more cautious, has also expanded since the Taliban returned to power. Beijing maintained diplomatic ties with the Taliban even before the US pulled out in 2021 and has since expanded economic ties. Chinese companies have shown interest in Afghanistan’s largely untapped mineral wealth, including copper and rare earth deposits. At the same time, Beijing has encouraged cross-border trade and limited infrastructure cooperation, hoping to gradually integrate Afghanistan into regional economic networks.
To manage the political emotions surrounding this relationship, China established a tripartite diplomatic system – the China-Pakistan-Afghanistan dialogue mechanism – aimed at promoting economic cooperation and security coordination between the three countries. The plan reflects Beijing’s belief that development and integration can gradually reduce instability in one of the world’s most volatile regions.
The outbreak of war between the two participants in the system now exposes the weakness of this approach.
At the heart of China’s dilemma is a fundamental mismatch between the tools it has and the forces driving the conflict. Beijing’s primary instruments in the region are economic: infrastructure investment, business incentives, and development financing. The dynamics shaping the Pakistan-Afghanistan conflict, however, are militant networks, contested borders, ideological rivalry, and domestic political pressure.
Economic cooperation can encourage cooperation in the long run, but it cannot easily solve insurgencies or deeply entrenched security problems.
China’s public message reflects the balance it must maintain between its two allies. Beijing has urged Islamabad and Kabul to resolve their differences through dialogue and negotiation while signaling its readiness to facilitate the lifting of the situation. Behind the scenes, Chinese diplomats have continued to communicate with both governments through established channels, including the trilateral coordination system linking the three countries.
Yet diplomacy alone cannot address the deep structural tensions fueling the conflict. The Durand Line – the colonial-era border dividing Afghanistan and Pakistan – is still disputed by Kabul and has long been a source of friction. Cross-border militant networks are becoming increasingly complex in terms of security, allowing armed groups to exploit borders and political competition.
In that sense, the current war is not just a bilateral conflict but the culmination of unresolved historical tensions.
The conflict also continues against the wider international situation where the threshold of confrontation between nuclear-armed states seems to be changing. Over the past decade, major powers have increasingly engaged in dangerous espionage involving nuclear-armed actors — from proxy attacks against Russia to frequent conflicts between nuclear rivals. South Asia itself has experienced similar events, including the 2025 India-Pakistan clash.
Pakistan is a nuclear-armed country, and although the current war does not directly involve another nuclear power, it takes place within a regional framework created by nuclear deterrence. This reality raises the stakes and highlights the increasing normality of dangerous confrontations in the international system.
For Beijing, the war raises uncomfortable questions about the central premise underlying its regional strategy: that economic integration can pave the way for political stability. The Roads Initiative has long been built on the idea that infrastructure – roads, railways, pipelines and ports – can gradually transform conflict zones into areas of economic prosperity.
But events along the Durand Line suggest the limits of that model.
Infrastructure can facilitate trade, but by itself it cannot overcome ideological insurgency, contested borders, or intense geopolitical competition. Economic means can encourage stability over time, but they cannot replace political consensus or good governance.
So the war between Pakistan and Afghanistan represents more than just another regional conflict. It is a serious test for China’s westward strategy and for the broader notion that progress alone can reshape Eurasia’s political landscape.
Whether Beijing can deal with this crisis without undermining its cooperation – or its strategic vision – remains unclear.
What is clear, however, is that the ongoing conflict on China’s western periphery threatens to redraw not only regional alliances but also the concepts governing one of the most ambitious geopolitical projects of the twenty-first century.
