In early 2024, the Government of India officially rejected China's unilateral naming of over 50 places in Arunachal Pradesh, a region constitutionally recognized as Indian territory. This move by China, reflected in its 2023 official gazette, constitutes a direct challenge to India's sovereignty and territorial integrity under both domestic and international law. India’s response underscores its assertion of legal and administrative control over Arunachal Pradesh, reinforcing its position amid ongoing border tensions along the Line of Actual Control (LAC).

Constitutional and Legal Framework Defining Arunachal Pradesh’s Territory

Article 1 of the Constitution of India explicitly includes Arunachal Pradesh within the territory of India. The Foreigners Act, 1946 empowers the government to regulate entry and manage border security, underscoring the state's sovereign control. Naming conventions within Indian territory fall under the purview of the Official Languages Act, 1963 (Section 3), which authorizes the government to standardize geographical names. Bilateral agreements such as the 1993 and 1996 Sino-Indian Agreements on Maintenance of Peace and Tranquility along the LAC emphasize preserving the status quo, prohibiting unilateral changes that alter ground realities.

• The United Nations Charter (1945), Article 2(4), prohibits the threat or use of force and unilateral territorial claims, reinforcing India’s legal position against China's naming.
• The Supreme Court ruling in Bharat Petroleum Corp. Ltd. v. N.R. Dongre (2000) affirms the inviolability of sovereign territory, strengthening India's stance.

Geopolitical Contestation and Border Dynamics

China’s unilateral naming of places in Arunachal Pradesh is part of a broader strategy to assert territorial claims in contested border areas. The LAC remains ill-defined and disputed, with China’s actions aimed at altering facts on the ground through symbolic and administrative measures. India’s rejection signals a firm diplomatic and legal rebuttal, reinforcing its physical and administrative presence in the region.

• The Indian Army maintains regular patrols and presence along the LAC to assert control.
• The Ministry of External Affairs (MEA) issues diplomatic protests and manages international communication on the issue.
• The Intelligence Bureau (IB) monitors border activities, providing inputs for strategic responses.
• The Border Roads Organisation (BRO) accelerates infrastructure projects to improve connectivity and military logistics.

Economic Significance of Arunachal Pradesh in India’s Strategic Calculus

Arunachal Pradesh’s strategic location on the India-China border influences India’s economic and infrastructure investments. The Union Budget 2023-24 allocated ₹3,500 crore specifically for infrastructure and development in border areas, reflecting the region’s importance. The state holds an estimated hydropower potential of 50,000 MW (Central Electricity Authority, 2022), critical for India’s energy security, though less than 0.5% is currently harnessed.

• Cross-border trade with China through Arunachal Pradesh remains negligible, under $0.1 million in 2023, due to border tensions (Ministry of Commerce, 2024).
• The Arunachal Frontier Highway, a 1,700 km infrastructure project budgeted at ₹40,000 crore, aims to improve connectivity and assert administrative control along the LAC.
• India conducts over 100 joint military exercises annually with allied countries to enhance border preparedness (Ministry of Defence, 2023).

Institutional Roles in Managing Arunachal Pradesh’s Border and Sovereignty

Multiple Indian institutions coordinate to uphold sovereignty and manage the Arunachal Pradesh border region. The MEA leads diplomatic engagement and international legal articulation. The MHA oversees internal security and border management, coordinating with the IB for intelligence. The BRO executes critical infrastructure projects enhancing mobility and military logistics. The Survey of India under MEA is the authoritative body on official geographical names and mapping, countering China’s fictitious naming. The Indian Army ensures ground presence and operational readiness along the LAC.

Comparative Analysis: India-China and Japan-China Naming Disputes

India’s rejection of China’s naming claims in Arunachal Pradesh parallels Japan’s dispute over the Senkaku/Diaoyu Islands in the East China Sea. Both countries emphasize effective administrative control and invoke international law to assert sovereignty. Japan relies on the United Nations Convention on the Law of the Sea (UNCLOS) to support its claims, highlighting the role of legal frameworks and physical control in contested maritime and land territories.

Policy Gaps in India’s Response to China’s Unilateral Actions

India’s approach primarily relies on bilateral diplomatic protests and ground-level administrative assertions without fully leveraging multilateral legal mechanisms. There is limited use of international judicial forums such as the International Court of Justice (ICJ) or UNCLOS arbitration to challenge China’s actions. This constrains India’s ability to internationalize the dispute and gain broader global support under established legal frameworks.

Significance and Way Forward

• India’s firm rejection of China’s naming claims reaffirms its constitutional sovereignty and territorial integrity.
• Strengthening infrastructure and administrative presence in Arunachal Pradesh is critical to counter symbolic and physical challenges.
• India should enhance its international legal strategy by engaging multilateral forums to delegitimize China’s unilateral actions.
• Coordinated diplomatic efforts with like-minded countries facing similar challenges (e.g., Japan) could amplify India’s position.
• Continuous intelligence and military preparedness remain essential to deter further Chinese incursions or symbolic assertions.
