India-China : Border Disputes and Management

Recently, India and China held their first Corps Commander-level talks in the Eastern Sector at the Wacha-Damai BPM Point in Arunachal Pradesh. It is against the backdrop of increased PLA patrol activity and localized stand-offs in Tasking, Upper Subansiri district of Arunachal Pradesh.

Key points

India and China are now trying to manage their border through more regular talks and a stronger presence on the ground.

The recent Corps Commander talks in the Eastern Sector (Arunachal) are new; earlier these talks were only for Ladakh. India is also building roads, bridges, and airfields; deploying more troops; and using meeting points, hotlines, and diplomatic talks to avoid clashes on the LAC.

But the core issues are still not solved, and there are differences on where the LAC lies, with China claiming Arunachal and India claiming Aksai Chin.

So, India needs a mix of things: better border infrastructure, keeping border villages populated through the Vibrant Villages Programme, reducing economic dependence on China, building partnerships with other countries, and at the same time continuing dialogue with China to keep peace in the long term.

1. Siliguri Corridor Security: The Sikkim sector and Doklam tri-junction are close to the Siliguri Corridor, India's narrow land link to the Northeast, making it crucial for national security.

2. Tawang's Strategic Importance: Tawang and Bum La provide India important defensive positions overlooking the Assam plains and strengthen strategic depth in the Northeast.

3. Geo-Cultural Significance: Tawang is an important center of Tibetan Buddhism and houses historic Tawang Monastery, giving the region wider geopolitical significance for Tibetan identity and religious affairs.

4. Countering Territorial Claims: China claims entire Arunachal Pradesh as 'Zangnan' (South Tibet). A strong presence in the Eastern Sector is vital to protect India's territorial integrity.

5. Water Security: The Yarlung Tsangpo-Siang-Brahmaputra river system makes Arunachal Pradesh strategically important for India's downstream water security and transboundary river cooperation with China.

6. Act East Policy: A secure Arunachal Pradesh is essential for strengthening border connectivity, economic integration, and India's Act East Policy, linking Northeast more effectively with Southeast Asia.

1. Special Representatives (SR) on Boundary Question: Established in 2003, it is the highest political-level mechanism to seek final political settlement for the 3,488-km boundary dispute.

2. Working Mechanism for Consultation and Coordination (WMCC): A diplomatic and military channel was set up in 2012 to coordinate on incidents along LAC and maintain peace, though it lacks the mandate to settle the boundary itself.

3. Corps Commander-Level Meetings: High-level military negotiations used to achieve tactical disengagement, de-escalation, and buffer zone creation during intense border stand-offs.

4. Border Personnel Meeting (BPM) Points: Designated locations along LAC where local military commanders from both sides meet to resolve ground-level friction.

5. Institutional Hotlines: Direct communication channels between regional military commands to quickly defuse misunderstandings before they escalate.

6. Foundational Treaties and Protocols:

1. Shift from Border Defense to Active Deterrence: After the 2020 Galwan clash, India strengthened its forward military posture by repositioning formations towards northern borders and deploying Rafale aircraft, S-400 air-defense systems, and BrahMos missiles to respond rapidly to PLA mobilization.

2. Closing Infrastructure Gap: India is accelerating all-weather connectivity along LAC. Arunachal Frontier Highway (NH-913), Sela Tunnel, and Nechiphu Tunnel, along with BRO-built roads, bridges, and advanced landing grounds, enable faster troop mobilization and sustained access to forward posts.

3. Securing Demographic Frontier: Through the Vibrant Villages Programme (VVP), India is developing strategically located border villages to reverse out-migration, strengthen civilian presence, and improve last-mile connectivity. This counters China's dual-use border villages.

4. Calibrated Economic De-risking: India tightened Chinese investments under Press Note 3 (2020), but in 2026 eased restrictions to permit limited investments, including from China, while retaining safeguards for strategic and sensitive sectors.

5. Building External Balancing: India has strengthened strategic partnerships through Quad (India, US, Japan, Australia) and wider defense cooperation, enhancing maritime, technological, and military capabilities to offset China's growing regional influence without creating a formal military alliance.

India-China border management in the Eastern Sector is moving towards more structured military talks and stronger deterrence on the ground. However, the underlying issues of overlapping LAC perceptions and competing territorial claims remain unresolved. For long-term stability, India needs a balanced approach: continuing dialogue to avoid escalation, strengthening border infrastructure and local presence through projects like Vibrant Villages, reducing strategic economic dependence, and building partnerships with like-minded countries.
