A new war is threatening the Eurasian economy, and it’s not Iran

The Afghanistan-Pakistan conflict on China’s doorstep is challenging the assumptions behind one of the most ambitious geopolitical projects

The outbreak of open hostilities between Pakistan and Afghanistan marks the most serious confrontation between the two neighbors since the Taliban returned to power in 2021. After weeks of escalating cross-border clashes and retaliatory strikes, Islamabad declared it was in a state of “open war” with the Taliban government following airstrikes on targets in Afghan cities and border provinces.

The violence shattered a fragile ceasefire brokered in October 2025 and has quickly become the deadliest escalation along the 2,600-kilometer Durand Line in years. Tens of thousands of civilians have been displaced, and the risk of a wider regional crisis is rising.

The immediate trigger lies in disputes over cross-border militancy. Pakistan accuses Kabul of harboring fighters from Tehreek-e-Taliban Pakistan (TTP), allegations the Taliban deny. Yet the geopolitical implications of this confrontation stretch far beyond the frontier. For China, the war represents not merely a security crisis but a direct challenge to its broader strategic vision for regional integration.

Among external stakeholders, China stands to lose the most from a prolonged rupture between Islamabad and Kabul.

For years, Beijing has sought to position Pakistan and Afghanistan as key nodes in a transregional economic architecture linking Central Asia, South Asia, and western China. At the center of this vision lies 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 region 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 meant to become a peripheral extension of this network. Beijing has explored linking Afghan transport routes, mineral resources, and transit corridors to the wider CPEC infrastructure system. Such integration would give landlocked Afghanistan access to maritime trade while tying Central Asian markets more closely to China’s western provinces.

War between Pakistan and Afghanistan therefore strikes directly at the geographic core of this economic vision.

China’s relationships with both countries underscore why the stakes are so high. Pakistan has long been China’s “all-weather strategic cooperative partner.” The relationship spans defense cooperation, military technology transfers, 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 committed tens of billions of dollars to Pakistan’s infrastructure, while Beijing views the country as a crucial gateway linking western China to the Indian Ocean.

China’s engagement with Afghanistan, though more cautious, has also expanded since the Taliban returned to power. Beijing maintained diplomatic channels with the Taliban even before the US withdrawal in 2021 and has since broadened economic contacts. Chinese firms have expressed 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 sensitivities surrounding these relationships, China established a trilateral diplomatic framework – the China-Pakistan-Afghanistan dialogue mechanism – aimed at promoting economic cooperation and security coordination among the three countries. The initiative reflects Beijing’s belief that development and connectivity can gradually reduce instability in one of the world’s most volatile regions.

The outbreak of war between two participants in that framework now exposes the fragility of this approach.

At the heart of China’s dilemma lies a fundamental mismatch between the tools it possesses and the forces driving the conflict. Beijing’s primary instruments in the region are economic: infrastructure investment, trade incentives, and development financing. The dynamics shaping the Pakistan-Afghanistan confrontation, however, are militant networks, contested borders, ideological rivalries, and domestic political pressures.

Economic integration can encourage cooperation over the long term, but it cannot easily resolve active insurgencies or deeply entrenched security dilemmas.

China’s public messaging reflects the delicate balance it must maintain between its two partners. Beijing has urged Islamabad and Kabul to resolve their differences through dialogue and negotiation while signaling its readiness to facilitate de-escalation. Behind the scenes, Chinese diplomats have remained in contact with both governments through established channels, including the trilateral coordination framework linking the three countries.

Yet diplomacy alone may not address the deeper structural tensions fueling the conflict. The Durand Line – the colonial-era border dividing Afghanistan and Pakistan – remains disputed by Kabul and has long been a source of friction. Cross-border militant networks further complicate the security landscape, allowing armed groups to exploit porous frontiers and political rivalries.

In that sense, the current war is not simply a bilateral dispute but the culmination of unresolved historical tensions.

The conflict is also unfolding against a broader global backdrop in which the threshold for confrontation between nuclear-armed states appears to be shifting. Over the past decade, major powers have increasingly engaged in risky brinkmanship involving nuclear-armed actors – from proxy attacks against Russia to recurring crises between rival nuclear states. South Asia itself has experienced such moments, including the India-Pakistan clash of 2025.

Pakistan is a nuclear-armed state, and although the current war does not directly involve another nuclear power, it takes place within a volatile regional ecosystem shaped by nuclear deterrence. This reality raises the stakes of escalation and highlights the growing normalization of high-risk confrontation in the international system.

For Beijing, the war raises uncomfortable questions about a key assumption underlying its regional strategy: that economic connectivity can pave the way for political stability. The Belt and Road Initiative has long been built on the idea that infrastructure – roads, railways, pipelines, and ports – can gradually transform conflict-prone regions into zones of economic prosperity.

But events along the Durand Line suggest the limits of that model.

Infrastructure can facilitate trade, but it cannot by itself overcome ideological insurgencies, contested borders, or deep geopolitical rivalries. Economic corridors may encourage stability over time, but they cannot substitute for political reconciliation or effective governance.

The war between Pakistan and Afghanistan therefore represents more than another regional conflict. It is a serious test for China’s westward strategy and for the broader assumption that development alone can reshape the political landscape of Eurasia.

Whether Beijing can navigate this crisis without undermining its partnerships – or its strategic vision – remains uncertain.

What is clear, however, is that the conflict now unfolding on China’s western periphery threatens to redraw not only regional alliances but also the assumptions underpinning one of the most ambitious geopolitical projects of the twenty-first century.
