China-Pakistan Military Collusion

In July 2025, India formally acknowledged China’s direct military and technological support to Pakistan during Operation Sindoor (May 7–10), marking a significant escalation in the China-Pakistan nexus. This unprecedented battlefield collusion represents a strategic shift in regional security dynamics and challenges India’s conventional deterrence framework.

Geostrategic and Diplomatic Collusion

• Direct Military Enabling by China: Unlike earlier India–Pakistan conflicts (1965, 1971, and 1999), China’s role evolved from passive diplomatic support to active military enablement. This included real-time ISR assistance, battlefield technology integration, and coordinated strategic inputs that directly enhanced Pakistan’s combat readiness and operational decision-making.
• Diplomatic Positioning Aligned with Pakistan: China refrained from immediately condemning the Pahalgam terror attack (April 22, 2025), delaying its official response. Its subsequent statements echoed Pakistan’s narrative, referring to India’s retaliatory strikes as “regrettable” and acknowledging Islamabad’s “security concerns”, thereby undermining the legitimacy of India’s counter-terror operations.
• Propaganda and Perception Management: Chinese state-affiliated media and digital platforms engaged in active psychological warfare, reinforcing Pakistan's claims of operational success. They downplayed the severity of the initial terror attack, exaggerated Indian losses, and portrayed India’s response as escalatory, indicating synchronised information warfare strategies.

Operational Integration and Technological Interoperability

• Deployment of Chinese-Origin Military Platforms: Pakistan deployed Chinese-origin J-10C fighter aircraft equipped with PL-15 beyond-visual-range missiles, along with HQ-9 air defence systems, during Operation Sindoor. This was the first-ever real combat use of these platforms, which had been refined through extensive bilateral exercises over the years.
• ISR and Satellite-Based Coordination: Real-time data and targeting assistance were provided through Chinese ISR systems and the BeiDou satellite navigation network, enhancing Pakistan’s missile accuracy and battlefield awareness. Reports suggest even civilian maritime assets were leveraged to monitor Indian naval activities, demonstrating non-traditional surveillance support.
• Multi-Origin Platform Integration via Chinese Systems: Pakistan successfully fused its Swedish-origin airborne early warning and control systems with Chinese surveillance infrastructure. This seamless interoperability across diverse platforms, enabled largely by Chinese protocols, reflects a matured level of tactical and systems integration.

Strategic Implications and Policy Recommendations

• One-Front Reinforced War as the Emerging Paradigm: The conventional doctrine of a “two-front war” has now transformed into a more immediate challenge of a “one-front reinforced war”, where Pakistan remains the principal aggressor with direct but non-overt Chinese military reinforcement. The collapse of the 2021 ceasefire understanding along the western front, along with continued military deployments in the north, has necessitated dual-front strategic readiness.
• Urgency for Doctrinal and Capability Enhancement: Pakistan’s ongoing procurement of cutting-edge Chinese military assets—including fifth-generation stealth aircraft, airborne surveillance systems, and missile defence platforms—indicates deepening defence ties. India must accelerate investments in ISR capabilities, drone warfare, electronic warfare, and network-centric operations to retain strategic parity.
• Strategic Signalling and Policy Realignment: India’s diplomatic strategy must now reflect the strategic reality of China’s operational complicity in Pakistan’s military adventurism. Strategic levers such as review of water-sharing treaties or non-kinetic punitive mechanisms can serve as calibrated responses. Moreover, greater unpredictability in India’s retaliatory posture will help deter adversarial collusion and avoid falling into operational traps set by a coordinated adversary.
