China’s recent actions along the China-India border, including dam construction and territorial claims, pose threats to India's sovereignty and regional stability. China's control over transboundary rivers exacerbates environmental and agricultural risks, impacting countries like India and Bangladesh. To counter these challenges, India must lead regional diplomatic efforts and strengthen multilateral coordination to safeguard its interests.
Recent incidents of Chinese aggression along the China-India border underscore growing vulnerabilities for India’s territorial integrity and sovereignty. Notable actions include:
India has condemned these actions, deeming them illegal and a direct threat to its sovereignty. The proposed hydropower project raises concerns about potential ecological and strategic vulnerabilities, particularly in downstream regions.
China’s unilateral control over transboundary rivers has impacted multiple South Asian countries:
In response, India is investing in hydropower projects, particularly in Arunachal Pradesh, to mitigate strategic vulnerabilities.
China continues its strategy of cartographic aggression, evident in:
Despite these tactics, international law, including rulings by the International Court of Justice (ICJ), does not validate territorial claims based solely on maps. However, China’s physical presence in disputed territories complicates India’s position.
China’s economic engagements coexist with territorial and water-related disputes across South Asia. Unlike Southeast Asia, South Asian countries lack collective mechanisms like the Mekong River Commission (MRC).
India, as a regional power, must lead efforts to:
A unified regional strategy is essential to safeguard India’s sovereignty and ensure stability in South Asia amidst China’s assertive policies.
India-China relations date back over 2,000 years, rooted in cultural and economic exchanges. The Silk Road facilitated trade and the spread of Buddhism from India to East Asia, shaping early ties. Until the pre-1950s, interactions were limited to pilgrimage and minor trade.
A new phase began after India’s independence in 1947 and China’s Communist Revolution in 1949, establishing the People's Republic of China (PRC). Diplomatic relations were formalized in 1950, with India recognizing the PRC as the legitimate government.
Tibet acted as a buffer until China's 1950 invasion and occupation, leading to a shared border. The annexation raised tensions, exacerbated by the construction of a highway through Aksai Chin in the 1950s, an area claimed by India.
In 1954, India and China signed the Panchsheel Agreement, emphasizing:
Despite this, tensions escalated as China’s territorial claims grew.
India’s Forward Policy, aimed at asserting territorial control, triggered further clashes, culminating in the Sino-Indian War of 1962. Disputes over Aksai Chin and differing border perceptions led to recurring skirmishes, including the Chola incident (1967) and 2020 clashes.
Post-1980s, efforts to rebuild ties led to China becoming India’s largest trading partner by 2008. Both countries expanded economic and strategic cooperation. However, relations remain strained due to border stand-offs along the Line of Actual Control, impacting diplomatic ties.
As the world’s most populous nations and fastest-growing economies, India and China hold significant geopolitical and economic influence. Their relationship is crucial but continues to face hurdles in achieving stability and mutual trust.
The core issue lies in the undefined and disputed 3,440 km (2,100-mile) border, which spans four Indian states — Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh — and the Union Territory of Ladakh. The dispute is divided into three sectors: Western, Middle and Eastern, each with unique complexities.
Historical Roots
Specific Disputed Areas along the LAC
The war highlighted the need for:
The 1962 conflict marked the beginning of a protracted border tension that persists, compounded by recurring skirmishes and diplomatic challenges.
The 1962 War marked a significant moment in Sino-Indian relations, leaving a legacy of unresolved disputes and military challenges. China's salami-slicing techniques, coupled with its post-war infrastructure developments, have continued to complicate border dynamics. However, subsequent decades have seen India respond assertively to Chinese provocations, showcasing resilience and military preparedness.
The Nathu La conflict was a turning point where India decisively countered Chinese aggression. After repeated infiltrations into the Nathu La region in Sikkim, the Indian Army laid a wire along the perceived border. This act led to clashes, culminating in a heavy artillery exchange. The conflict lasted from September 6 to September 15, 1967, resulting in significant Chinese casualties (approximately 400 soldiers) and bolstering India's morale after the 1962 debacle.
Following the Nathu La incident, Chinese troops intruded into the Cho La Pass, a critical link between Sikkim and Tibet. Hostilities escalated on October 1, 1967, resulting in hand-to-hand combat and eventual military skirmishes. Despite the loss of 88 Indian soldiers, India successfully repelled Chinese forces, marking a second military victory that year.
China’s objections to India granting statehood to Arunachal Pradesh in 1986 reignited tensions. In Sumdorong Chu Valley, Chinese troops built infrastructure, prompting India to launch Operation Falcon, which resulted in an extended standoff. This period saw Indian and Chinese forces positioned eyeball-to-eyeball until China retreated. The standoff underscored India's enhanced military capability and determination to protect its sovereignty.
The 1993 Agreement on the Maintenance of Peace and Tranquility along the Line of Actual Control was a diplomatic milestone following the 1987 standoff. It formalized mechanisms for de-escalation and marked the beginning of structured border negotiations. While significant, it did not resolve the fundamental territorial disputes.
India's strategic victories in 1967 and 1987 and subsequent diplomatic engagements reflect its evolving approach to China's persistent challenges. These events highlight India's resolve to safeguard its borders and emphasize the necessity of robust military preparedness and sustained diplomatic efforts in countering China's expansionist strategies.
The 1993 Agreement on the Maintenance of Peace and Tranquility along the Line of Actual Control (LAC) marked a significant diplomatic effort between India and China. It formalized both nations' acceptance of the LAC's definition across the Western, Middle and Eastern sectors. Provisions included:
This pact aimed to reduce border tensions and promote stability.
Despite the agreements, China's People's Liberation Army (PLA) has repeatedly violated the pact. Key incidents include:
The Galwan clash marked the end of decades of peace along the LAC.
Tensions escalated due to India's infrastructure projects like the Darbuk-Shyok-DBO Road, critical for troop movement to Daulat Beg Oldi (DBO).
India’s strategy now emphasizes enhanced border infrastructure, exemplified by the 255-km Darbuk-Shyok-DBO road, which drastically reduces travel time and improves troop mobility near the LAC.
The region west of Daulat Beg Oldi includes Gilgit-Baltistan, part of Pakistan Occupied Kashmir (POK) and the China-Pakistan Economic Corridor (CPEC). China fears that India’s strategic leverage in the area could disrupt the CPEC and jeopardize the Belt and Road Initiative (BRI), posing risks to China's socio-economic and political stability.
Additionally, India’s infrastructure development along the Line of Actual Control (LAC) and statements claiming Aksai Chin as part of Indian territory have heightened China's geopolitical insecurities.
India and China have engaged in military and diplomatic talks to reduce tensions. The Five-Point Agreement formulated in recent discussions highlights the following things:
Several bilateral agreements have sought to address border disputes:
Five Border Personnel Meeting (BPM) points facilitate military-level talks:
Package Deal
China proposed a status quo recognition: its control over Aksai Chin and India’s sovereignty over Arunachal Pradesh. This offer was rejected by India, citing potential further aggression by Beijing.
LAC Plus Solution
This involved recognizing the LAC status quo with additional concessions from China in the west. However, Beijing hardened its stance post-1985, focusing on areas like Tawang, making the solution infeasible for India.
The border dispute remains unresolved due to strategic and political complexities. Arun Shourie aptly noted that there is a need for caution emphasizing that agreements are valuable only if they are enforceable and violations incur significant costs. India must strengthen its border infrastructure and enhance military readiness while maintaining robust diplomatic engagements to secure long-term stability.
