‘Beijing’s Durand Trial’ reflects an escalating struggle to project domestic security logic beyond its western frontier, specifically the Xinjiang Uyghur Autonomous Region (XUAR). At the core of Beijing’s security doctrine are the ‘Three Evil Forces’—terrorism, religious extremism and separatism—viewed as threats to state stability. This framework underpins the Chinese Communist Party’s (CCP) ‘Strike Hard’ campaigns to suppress the anti-state elements. Consequently, this domestic securitisation strategy has spilt over borders as Beijing seeks to mitigate instability in Afghanistan and Pakistan. Although it has attempted to mediate cross-border militancy between Kabul and Islamabad, these efforts have exposed clear limitations. From Xinjiang to the Durand Line, China’s security model reveals a widening chasm between operational reality and strategic ambition.

The Sword of Damocles

The second phase of the China-Pakistan Economic Corridor (CPEC) faces mounting challenges in Balochistan—the corridor’s gateway to the Arabian Sea. Local opposition has intensified through insurgent violence led by the Baloch Liberation Army-Jeeyand (BLA-J) under the Baloch Raaji Aajohi Sangar alliance. Deploying ‘hit-and-run’ and ‘fidayeen’ (suicide) tactics under Operation Zir Pahazag, these groups target Chinese-linked projects and personnel, accusing Beijing of resource exploitation and demanding an immediate halt and exit.

This insurgency is rooted in underlying grievances over socio-economic exclusion, unequal resource distribution and state repression. In this context, Chinese investments are perceived as an extension of a government-centric model that marginalises locals. Eventually, this persistent insecurity has delayed projects in Gwadar and disrupted timelines. While China remains apprehensive, Islamabad’s reaction is preoccupied with external threats—specifically India, leaving the fundamental drivers of instability unaddressed.

For China, such setbacks are significant. Despite expanding counterterrorism support through intelligence and finance, outcomes remain unchanged. Pakistan appears reluctant to adopt China-style counterinsurgency measures or to permit Chinese ‘boots on the ground.’ The all-weather partnership is constrained by domestic sentiments and strategic limits, including its relationship with the United States. A significant gap persists between China’s security expectations and Pakistan’s capacity to realise them. As BLA actions display signs of regional spillover in Iran and Afghanistan, Beijing’s concerns have intensified. Did the CCP underestimate the complexity of Pakistan’s internal unrest and its broader strategic limitations?

An Albatross around Beijing’s neck

The two major crossings along the 2,640 km Durand Line—Torkham and Chaman-Spin Boldak—remain plagued by militant activity. Since the establishment of the Second Islamic Emirate of Afghanistan, cross-border violence by Tehrik-e-Taliban Pakistan (TTP) has surged, deteriorating Pakistan’s domestic security. Moreover, Balochistan friction provides space for TTP expansion in Pakistan’s ‘Pashtun regions’, particularly the former Federally Administered Tribal Areas (FATA).

Both the TTP and Taliban reject the Durand Line as a legitimate boundary and criticise Pakistan’s border control mechanism of dividing the Pashtun communities along the border. For the Taliban, this rejection reflects continuity with the position of its founding leader, Mullah Omar. Consequently, any move by the Emir to prioritise Pakistan’s interests risks being perceived as national betrayal, particularly given the significant Pashtun population within Afghanistan. Moreover, Taliban support to TTP remains critical for maintaining internal cohesion against threats like the Islamic State’s Khorasan Province (ISKP) and the Al-Qaeda linked East Turkestan Islamic Movement (ETIM), while also providing strategic leverage against Pakistan.

Recently, the expanding operations of the ISKP against Chinese investments and local ventures have further complicated the security landscape. Designated as a Foreign Terrorist Organisation (FTO), ISKP adheres to a takfiri ideology that frames Chinese presence as a symbol of intrusion and condemns the Taliban for engaging with foreign powers. As a result, it justifies its attacks as ideologically motivated retaliation and a warning to foreign actors.

Similarly, concerns over ETIM, headquartered in Afghanistan, intersect with this security environment. China emerges as a shared target, albeit for motivations distinct from the ISKP. Although evidence of sustained coordination remains limited, the potential for ideological convergence shapes Beijing’s cautious posture towards Kabul. Notably, both the TTP and ETIM assisted the Taliban in taking over power in 2021, compelling it to adopt a calibrated strategy shaped by ideological affinity, structural limitations and concerns over potential defections to ISKP.

Mired in these overlapping challenges, it is doubtful the Taliban can guarantee the level of security Beijing expects in exchange for its de jure recognition and economic assistance. Instead, the bleak security architecture may compel China to reassess both its financial commitments and plans to connect Xinjiang to Kabul via the Wakhan corridor.

The Hydra effect

Much like the Lernaean Hydra, China’s approach in Xinjiang has inadvertently decentralised the threats—transforming a localised security issue into a fragmented transnational crisis. Research by the Afghan Studies Centre indicates that the ETIM operates across Central Asia and the Afghanistan-Pakistan border region, often coordinating with the BLA, TTP and the Islamic Movement in Uzbekistan (IMU) to target Chinese ventures. Likewise, ISKP advances a transnational agenda centred on ‘Greater Khorasan’ that overlaps with China’s Belt and Road corridors in the west, turning connectivity routes into vulnerabilities. For Beijing, stability in Xinjiang is tied to securing overland energy routes and overseas assets. This expanding threat landscape intersects with China’s growing economic exposure in Central Asia and Pakistan.

While these corridors enhance regional connectivity, they demand a sustained security that is increasingly difficult to guarantee. The persistence of militant networks and volatility along the Afghanistan-Pakistan border challenges this ‘development-as-security’ model, raising a critical question: Can economic integration stabilise regions defined by entrenched militancy and cross-border insecurity? Yet, this approach assumes that economic development can mitigate ideological extremism.
