‘Must reflect’: India on China’s support to Pakistan in Operation Sindoor
China's state broadcaster CCTV aired an interview confirming that a Chinese engineer from AVIC's Chengdu Aircraft Design and Research Institute provided on-site technical support to Pakistan during Operation Sindoor — a public acknowledgement by Beijing of its direct military-technical assistance to Pakistan during the four-day armed confrontation.
India issued a pointed diplomatic response, stating through official channels: "It is for nations who consider themselves responsible to reflect whether supporting attempts to protect terrorist infrastructure affects their reputation and standing."
India characterised Operation Sindoor as "a precise, targeted, and calibrated response to the terrorist attacks in Pahalgam, aimed at destroying state-sponsored terrorist infrastructure operating out of Pakistan and at its behest."
Operation Sindoor was launched on the night of May 6–7, 2025, targeting nine terrorist infrastructure sites in Pakistan and Pakistan-occupied Kashmir (PoK), including locations linked to Jaish-e-Mohammed (JeM) and Lashkar-e-Taiba (LeT) at Bahawalpur, Muridke, Muzaffarabad, and Kotli.
The operation was triggered by the April 22, 2025 Pahalgam terror attack in which 26 civilians — mostly tourists — were killed.
India–China Relations: Historical Framework and the Border Dispute
India and China share a 3,488 km disputed boundary, divided into three sectors: the western sector (Ladakh — where China controls Aksai Chin), the middle sector (Himachal Pradesh/Uttarakhand), and the eastern sector (Arunachal Pradesh — which China claims as "South Tibet"). The Line of Actual Control (LAC) — not a formally demarcated boundary — serves as the de facto border. The term "LAC" was first used by Chinese Premier Zhou Enlai in a 1959 letter to Indian Prime Minister Jawaharlal Nehru, and the current LAC took shape after the 1962 Sino-Indian War. The two countries have no settled boundary and maintain the Special Representatives Mechanism (SRM), established in 2003, for border negotiations.
Key Details
- 1962 Sino-Indian War: led to current LAC configuration; India lost Aksai Chin
- Five Principles of Peaceful Coexistence (Panchsheel): signed 1954, India-China; provides diplomatic framework
- 1993 Agreement on LAC maintenance: bilateral agreement to maintain peace along LAC
- SRM (Special Representatives Mechanism): established 2003 under "Declaration on Principles for Relations and Comprehensive Cooperation"
- 2020 Galwan Valley clash: 20 Indian soldiers killed; triggered four-year disengagement process
- October 2024 patrolling agreement: India and China reached an agreement on LAC patrolling resumption, resolving the 2020 standoff
- China's "salami-slicing" strategy: incremental territorial occupation along disputed borders
China's acknowledged support for Pakistan during Operation Sindoor introduces a new and explicit dimension to the India-China-Pakistan triangular dynamic. India's diplomatic response — framed around "responsible nations" — signals that Beijing's actions during the conflict will factor into the broader bilateral relationship.
India–Pakistan: Cross-Border Terrorism and India's Doctrine
Cross-border terrorism from Pakistan has been a persistent challenge to India's internal security since the late 1980s. State-sponsored non-state actors — particularly Jaish-e-Mohammed (JeM), founded in 2000 by Masood Azhar, and Lashkar-e-Taiba (LeT), founded in 1986–87 — have been designated as terrorist organisations by the UN Security Council (UNSC), the United States, the European Union, and India. India's articulated doctrine — particularly after the 2016 Uri surgical strikes and the 2019 Balakot air strikes — distinguishes between the "new normal" of responding to terrorism on Pakistani soil and traditional escalatory concerns. Operation Sindoor represents a continuation and escalation of this doctrine, with strikes on a wider set of targets including locations in Pakistan's Punjab province (not just PoK).
Key Details
- Jaish-e-Mohammed (JeM): founded 2000 by Masood Azhar; UN-designated terrorist organisation; responsible for 2001 Parliament attack, 2016 Pathankot and Uri attacks, 2019 Pulwama attack
- Lashkar-e-Taiba (LeT): founded 1986–87 by Hafiz Saeed; UN-designated; responsible for 2008 Mumbai attacks
- 2016 Surgical Strikes: across LoC in PoK targeting launch pads (first publicly acknowledged cross-LoC action)
- 2019 Balakot air strike: first Indian air strike inside undisputed Pakistani territory since 1971
- Operation Sindoor (May 7, 2025): nine sites targeted in Pakistan and PoK; escalatory step — included strikes in Punjab province (Bahawalpur, Muridke)
- India's position: cross-border terrorism constitutes an act of aggression, justifying the right of self-defence under Article 51 of the UN Charter
China's acknowledgement of direct military-technical support to Pakistan during Operation Sindoor — including to systems that may have been deployed against Indian forces or used to protect the targeted infrastructure — places Beijing in the position of having actively supported a state that India is engaged with in an active anti-terror operation.
China–Pakistan Strategic Partnership and Military-Technical Cooperation
China and Pakistan describe their relationship as an "All-Weather Strategic Cooperative Partnership." China is Pakistan's largest arms supplier, accounting for approximately 82% of Pakistan's arms imports over the 2019–2023 period (SIPRI data). Key Chinese defence transfers to Pakistan include the JF-17 Thunder (jointly produced combat aircraft by AVIC's Chengdu Aircraft Corporation and Pakistan Aeronautical Complex), the HQ-9 air defence system, and various naval platforms including Type 054A frigates. China is also the primary financier of the China-Pakistan Economic Corridor (CPEC) — a flagship Belt and Road Initiative (BRI) project involving approximately $62 billion in investment through roads, railways, energy infrastructure, and the development of Gwadar Port on the Arabian Sea.

- China-Pakistan "All-Weather Strategic Cooperative Partnership": phrase used since 2015
- China's share of Pakistan's arms imports (2019–2023): ~82% (SIPRI)

China's on-site technical support during Operation Sindoor, admitted publicly by Beijing, demonstrates that the China-Pakistan military-technical partnership extends to active support during armed confrontations with India — moving beyond arms transfers to real-time operational assistance, a qualitative escalation in India's threat calculus.
