India–China Relations: Border, Trade and Strategic Competition
GS2 · India and its Neighbourhood
Historical arc
India was among the first non-communist countries to recognise the People's Republic of China, in 1950. The two signed the Panchsheel Agreement (1954, on trade with Tibet). Its five principles of peaceful coexistence were:
- mutual respect for territorial integrity and sovereignty;
- mutual non-aggression;
- non-interference in internal affairs;
- equality and mutual benefit;
- peaceful coexistence.
The "Hindi–Chini bhai bhai" phase ended with China's occupation of Tibet (1950), the Dalai Lama's flight to India (1959), and the 1962 war, in which China occupied Aksai Chin. The Sumdorong Chu standoff (1986–87) was followed by Rajiv Gandhi's visit in 1988, which started normalisation.
Border management agreements
| Year | Agreement |
|---|---|
| 1993 | Maintenance of Peace and Tranquillity along the LAC |
| 1996 | Confidence-building measures in the military field (no firearms use near LAC) |
| 2003 | Special Representatives mechanism for boundary question |
| 2005 | Political Parameters and Guiding Principles for a boundary settlement |
| 2012 | Working Mechanism for Consultation and Coordination (WMCC) |
| 2013 | Border Defence Cooperation Agreement |

The boundary is about 3,488 km long (India's figure). It has three sectors:
- Western sector (Ladakh): China holds Aksai Chin, which India claims.
- Middle sector: Himachal Pradesh and Uttarakhand; the least contentious.
- Eastern sector: Sikkim and Arunachal Pradesh. China claims Arunachal as "South Tibet" and has issued "standardised names" for places in it, which India rejects. India's position is that the McMahon Line (Simla Convention, 1914) is the boundary.
Crises: Doklam and Galwan
Doklam (2017). A 73-day standoff took place at the India–Bhutan–China trijunction when China attempted to extend a road on the Doklam plateau, which Bhutan claims. Indian troops intervened in support of Bhutan, and the standoff ended with disengagement.

Eastern Ladakh (2020). Chinese troops amassed at several friction points: Galwan, Pangong Tso, Gogra–Hot Springs and Depsang. On 15 June 2020 a clash in the Galwan Valley killed 20 Indian soldiers, the first deadly clash since 1975. Disengagement followed after many rounds of Corps Commander talks: Pangong (2021), Gogra (2021), and Hot Springs PP-15 (2022). In October 2024 an agreement on patrolling arrangements covered Depsang and Demchok. The leaders then met at the BRICS summit in Kazan, and the Special Representatives resumed talks in December 2024. In 2025, steps to normalise relations included the resumption of the Kailash Mansarovar Yatra and of direct flights, and Prime Minister Modi attended the SCO summit in Tianjin (Aug–Sept 2025). The underlying boundary dispute and the de-escalation of the large troop build-up remain unresolved.
India's responses:
- Infrastructure: border roads, the Atal Tunnel (Rohtang, 2020), the Sela Tunnel (2024) and the Vibrant Villages Programme (2023) for northern border villages.
- Economic measures: a ban on many Chinese apps (2020) and Press Note 3 (2020), which requires government approval for FDI from countries sharing a land border.
- Diplomatic: closer ties with the Quad.
Economic relations: interdependence and imbalance
China is one of India's largest trading partners. India runs a large and widening trade deficit with China, of the order of US$85–100 billion in recent years. India imports electronics, machinery, active pharmaceutical ingredients (APIs), solar cells and chemicals, and exports mainly raw materials such as ores, cotton and organic chemicals. Dependence on China for critical inputs is a strategic vulnerability, as shown when supply chains were disrupted in 2020. India responded with:
- Production Linked Incentive (PLI) schemes.
- Anti-dumping duties.
- Quality control orders.
- Staying out of the RCEP (India withdrew in November 2019, citing concerns about Chinese imports).
Strategic competition beyond the border
- China–Pakistan axis: the China–Pakistan Economic Corridor (CPEC) under the Belt and Road Initiative (BRI) passes through Gilgit-Baltistan in PoK, which India says violates its sovereignty. India has refused to join the BRI.
- Indian Ocean: Chinese naval presence, its base in Djibouti (2017), research and survey vessels, and port projects (Hambantota in Sri Lanka, Gwadar in Pakistan, Kyaukphyu in Myanmar). These are sometimes called the "String of Pearls".
- Water: China is building dams on the Yarlung Tsangpo (Brahmaputra), including a very large project in the lower reaches approved in 2024. India and China share hydrological data under MoUs, and an Expert Level Mechanism (2006) exists.
- Multilateral: China has blocked India's NSG membership and earlier blocked the UN listing of terrorists, such as Masood Azhar until 2019. Yet both cooperate in BRICS, SCO and on climate issues as developing countries.
- Tibet and the Dalai Lama: the succession question is a sensitive issue.
Way forward
India's approach is often summarised as "compete where necessary, cooperate where possible, avoid conflict". This means:
- Maintain military deterrence and build border infrastructure.
- Reduce import dependence through manufacturing and diversification ("China+1").
- Deepen partnerships (Quad, Japan, France, ASEAN).
- Keep channels open for de-escalation.
- Insist that peace on the border is the basis for normal relations, as India stated after 2020.

Understanding the LAC: why clashes happen
The Line of Actual Control has never been jointly demarcated on the ground or on maps. An exchange of maps took place only for the middle sector, in 2002. Each side patrols up to the line it perceives, so the two claim lines overlap in several "grey zones". During patrols the two sides meet face to face, and the 1996 and 2005 protocols laid down rules to avoid violence, including the no-firearms understanding. The 2020 crisis broke these norms through large troop deployments. Since then "buffer zones" have been created at some friction points where neither side patrols. Critics say these zones restrict India's access to traditional patrolling points. The 2024 agreement restored patrolling in Depsang and Demchok.
Analysis: asymmetry and interdependence
China's economy is roughly five times India's, and its defence budget is several times larger. This asymmetry shapes India's strategy. India's internal balancing includes building military capabilities, infrastructure and manufacturing. Its external balancing works through partnerships such as the Quad (India, US, Japan, Australia), the I2U2, and ties with France and ASEAN. India's tradition of strategic autonomy means it avoids formal alliances. At the same time, Indian industry relies on Chinese inputs. The Economic Survey 2024 suggested that greater Chinese FDI in some sectors could help India integrate into global value chains and reduce the trade deficit. This illustrates the dilemma of trying to reduce dependence while staying competitive.
Cooperation areas
India and China share interests in reform of global financial institutions, climate negotiations (both resist binding obligations that ignore differentiated responsibility), WTO issues such as food security, and the BRICS New Development Bank. India is also a founding member of the Asian Infrastructure Investment Bank (AIIB, 2016), headquartered in Beijing. India is the second-largest shareholder and one of its largest borrowers.
Common prelims traps
- Aksai Chin is administered by China but claimed by India as part of Ladakh.
- Shaksgam Valley was ceded by Pakistan to China in 1963; India does not recognise the transfer.
- Pangong Tso is a lake roughly 60% in Chinese-controlled territory, with "fingers" on its north bank.
- The Nathu La and Shipki La passes have been used for border trade; the Lipulekh and Nathu La routes are used for the Kailash Mansarovar Yatra.
