Authors : Tanuj Samaddar, A R Sangeetha, Md. Rizwan, Ankush Kumar Within the Belt and Road Initiative (BRI) framework, the China-Pakistan Economic Corridor (CPEC) is a flagship undertaking of great significance throughout South Asia as a strategically significant regional, economic, and geopolitical undertaking. Wolf (2019) conceived the corridor between the Xinjiang Uyghur Autonomous Region of China and the Gwadar Port in the Balochistan province of Pakistan via a sprawling network of roads, railways, energy initiatives, and special economic zones (SEZs). New Delhi sees CPEC as a significant security threat that violates India’s sovereignty, escalates border tensions, and redraws regional power disparities, even though Beijing touts it as a forerunner of economic revitalization and regional connectivity. (Pant and Joshi , 2017) Its passage through the disputed Gilgit-Baltistan territory, a region still a crucial part of the former princely state of Jammu and Kashmir and subject to territorial claim by India, is the main argument supporting India’s strategic concerns on CPEC. CPEC’s effects cover a more Chinese military presence in the Indian Ocean Region, the militarization of economic corridors, and regional economic architecture realignment. Through the lenses of sovereignty, economic dependence, military tactics, and geopolitical reconfigurations, this research charts the complex security consequences of CPEC for India. This study seeks to provide a subtle view of the manifold security threats presented by CPEC and the corresponding countermeasures India uses to minimize its negative effects by combining a large amount of academic work. The sovereignty narrative surrounding the CPEC has caused intense unease among Indian policy and strategic circles. Pant and Joshi (2017) among others argue that the corridor’s crossing through Gilgit-Baltistan directly violates India’s territorial integrity, hence supporting Pakistan’s effective administrative authority over the area. Kumar (2019) adds that China’s infrastructure related spending in the area practically acknowledges Pakistan’s territorial claims, thereby worsening the legal and political deadlock over Kashmir. India’s strategic apprehensions are further accentuated by the potential encirclement effect precipitated by China’s economic corridors, collectively known as the ‘String of Pearls’ strategy (Brewster, 2018). The encirclement theory posits that Beijing’s financial statecraft is fundamentally tied to its larger geostrategic aims, where infrastructural investments act as channels for security leverage In addition, India’s positive outreach to regional actors—namely Iran, Afghanistan, and Central Asian Republics—through infrastructural ventures like the Chabahar Port and the International North-South Transport Corridor (INSTC) is indicative of a move to offset Pakistan’s geoeconomic centrality in CPEC. The synergizing of Indo-Pacific alliances, more specifically through the Quadrilateral Security Dialogue (Quad), is an adjunct mechanism to counterbalance Chinese strategic gains (Jacob, 2020). Economic and Military Aspects of CPEC Influencing India’s National Security The China-Pakistan Economic Corridor (CPEC) has fundamentally altered the economic landscape of South Asia, with notable implications for India’s national security. Pakistan’s increasing reliance on Chinese investments has spurred significant infrastructure development along India’s western border, raising fears of strategic encirclement. The corridor linking Gwadar Port to China’s Xinjiang province enhances Pakistan’s logistical capabilities, allowing for more efficient military mobilization (Pant,2018) . Chinese involvement in vital transport and energy projects in Pakistan challenges India’s trade networks, potentially diminishing India’s influence in South Asia (Small, 2020). Furthermore, as Pakistan grapples with a growing debt burden from the China-Pakistan Economic Corridor (CPEC) projects, this economic imbalance has become closer aligned with Chinese policies, thereby complicating India’s geopolitical position (Rana,2021). The military implications of the China-Pakistan Economic Corridor (CPEC) present significant security concerns for India, especially given the increasing Chinese presence at Gwadar Port. Analysts indicate that what was initially intended as a trade hub may now serve dual military functions, potentially allowing China to station naval assets in the Arabian Sea (Singh, 2019). This development raises apprehensions about a possible Chinese-Pakistani naval partnership, which could undermine India’s maritime security. Moreover, CPEC traverses Pakistan-occupied Kashmir (POK), a region that India claims as its own. China’s investments in infrastructure, including highways and railways in POK, bolster Pakistan’s ability to mobilize forces along the Line of Control (LoC), heightening border tensions. Furthermore, reports suggest that Chinese-funded security deployments along the CPEC route have increased militarization in border areas, raising the likelihood of potential conflict scenarios (Sharma, 2022). The expanding military and economic partnership between China and Pakistan has prompted a more assertive Pakistani approach to border disputes, resulting in a rise in ceasefire violations along the Line of Control (LoC) (Malik, 2022). This corridor enhances China’s geo-economic influence, positioning it as a key South Asian player and marginalizing India’s role in the region. The potential for a two-front war scenario—where India could face simultaneous military threats from China to the north and Pakistan to the west—has become a significant concern for India’s defense strategists. Furthermore, China’s debt-trap diplomacy in Pakistan raises alarms about long-term geopolitical realignments, posing an additional threat to India’s strategic interests. The China-Pakistan Economic Corridor (CPEC) has significantly transformed India’s national security landscape, impacting economic sovereignty and military readiness. The corridor’s path through Pakistan-occupied Kashmir (PoK) has exacerbated border conflicts, and Pakistan’s increasing economic dependence on China fortifies the Sino-Pak alliance, thereby challenging India’s position in the region. From a military perspective, the potential dual-use nature of Gwadar Port, alongside infrastructure that enhances Pakistan’s military mobility, heightens the risk of cross-border skirmishes. In response to these developments, India must bolster its border security, strengthen alliances with global partners, and seek to expand alternative trade routes, such as Chabahar Port. Addressing these complex challenges necessitates a comprehensive security strategy integrating diplomatic, economic, and military measures to protect India’s strategic interests. Impact of CPEC in Indo-Pak border In such a scenario, which is likely to be created by India’s concessions to Pakistan, the Indo-Pak border dimensions along with border dynamics would substantially change. Such considerations most certainly include the geographical base of Pakistan and India as an extension of these countries to Afghanistan as it brings the vast areas of Balochistan, Sindh, and the southern provinces of Afghanistan into geographical proximity to the western borders of northern India via scanty highlands and plateaus connecting these desert-based provinces.
