'Arunachal is integral part of India, nothing can change this': India tells China
The Ministry of External Affairs rejected China's fresh objection to India formally notifying standard (Indian) names for 27 places and geographical features in Arunachal Pradesh on official maps, including mountain passes, settlements, and a high-altitude lake.
The MEA reiterated that "Arunachal Pradesh was, is, and will remain an integral and inalienable part of India," stating that naming exercises by any side cannot alter this status.
The set of 27 locations includes Longju, a site along the Line of Actual Control (LAC) associated with an armed border clash between Indian and Chinese forces in 1959, prior to the 1962 war.
The exchange forms part of a recurring pattern: China has periodically issued its own "standardised" Chinese names for places in Arunachal Pradesh since 2017, which India has consistently rejected as having no bearing on sovereignty or territorial status.
Toponymy as an Instrument of Territorial Assertion
States sometimes use the unilateral naming or renaming of geographic features as a low-cost, non-military way of signalling or reinforcing a territorial claim, without altering facts on the ground. This is a recognised pattern in international boundary disputes and is distinct from actual military posturing.
Key Details
- China's naming exercises in Arunachal Pradesh began in April 2017, widely read as a response to the Dalai Lama's visit to the state that year; subsequent batches followed in 2021 (15 places), 2023 (11 places), and April 2026 (23 places), bringing the cumulative total to over 110 Chinese-language place names.
- Comparable "cartographic assertion" disputes exist elsewhere, such as competing names for the Sea of Japan/East Sea and unilateral island-naming in the South China Sea.
- India's response of officially notifying Indian names for the same 27 locations on Survey of India maps mirrors this practice, asserting administrative and cartographic sovereignty through the same instrument China uses.
The current dispute over 27 place names is the latest round in this recurring toponymic contest, showing how both sides use naming as a symbolic extension of their underlying territorial claim over the Eastern Sector.
Survey of India and Official Mapping Authority
The Survey of India, under the Department of Science and Technology, is India's national mapping agency and the sole authority for producing the "Standard Map" of the country used in official, legal, and educational contexts, making its notifications on place names carry formal government weight.
Key Details
- Established in 1767, making it one of the oldest scientific departments of the Government of India.
- Operates under the Ministry of Science and Technology; its base maps are governed by the National Map Policy, 2005, which distinguishes freely-available "Defence Series Maps" restrictions from openly published maps of India's boundaries.
- Names notified through the Survey of India for locations in Arunachal Pradesh become the official reference used in subsequent government records, education, and international representations of India's boundary.
The 27 place names India notified are being incorporated into the Survey of India's official mapping of Arunachal Pradesh, giving the naming exercise legal and administrative permanence beyond a one-off diplomatic statement.
The 1959 Longju Incident and the Pre-1962 Border Timeline
Longju, one of the 27 renamed locations, was the site of an armed clash between Indian and Chinese troops in August 1959, making it a historically significant marker in the lead-up to the 1962 India-China War.
Key Details
- The Longju clash (25 August 1959) came months after the Dalai Lama's flight into exile in India (March 1959) following the Tibetan uprising against Chinese rule, an event that sharply escalated India-China tensions over Tibet and the frontier.
- It followed the earlier Kongka Pass incident (Ladakh, October 1959) and preceded the full-scale 1962 war, forming part of a sequence of frontier incidents through which the unresolved boundary dispute first became militarily active.
- The area lies in the Eastern Sector, broadly along the alignment of the McMahon Line drawn at the 1913-14 Simla Convention, which China does not recognise since it never ratified that agreement.
Including Longju among the 27 officially named locations links the present cartographic dispute to the historical starting point of the unresolved boundary conflict, reinforcing India's administrative presence at a site with direct historical significance to the dispute.
- 27 places and geographical features in Arunachal Pradesh were given official Indian names in the latest exercise, including Longju.
- China's renaming exercises: 6 places (April 2017), 15 places (2021), 11 places (2023), 23 places (April 2026) — a cumulative total exceeding 110 Chinese-language names since 2017.
- Longju incident: 25 August 1959, months after the Dalai Lama's arrival in India (March 1959).
- McMahon Line: demarcated at the Simla Convention, 1913-14; not recognised by China, which claims Arunachal Pradesh as "Zangnan" (Southern Tibet).
- Survey of India: established 1767; functions under the Department of Science and Technology and issues the country's official Standard Map under the National Map Policy, 2005.
