India has formally identified and marked 27 locations and geographical features in Arunachal Pradesh with standard names on official Survey of India maps, in a move that comes amid China’s repeated attempts to assign its own names to places in the border state.
The Union Home Ministry said on August 7 that the exercise was undertaken in consultation with the Arunachal Pradesh government to facilitate the “precise identification” of the locations and increase public awareness.
The list includes 21 land areas, four mountain passes, one lake and one memorial, with Longju emerging as the most politically sensitive location because the village has been under Chinese control since the 1959 Longju incident but remains within India’s claimed boundary.
India’s latest move is widely being viewed as a cartographic and administrative assertion of its territorial position rather than simply a symbolic response to Beijing. China, which refers to Arunachal Pradesh as “Zangnan” or “South Tibet”, has maintained that the region belongs to China and that Beijing has the sovereign right to standardise names there.
In April 2026, Chinese Foreign Ministry spokesperson Guo Jiakun defended Beijing’s naming exercise, saying China had the right to issue standard names for places in what it considers its territory, while also saying that China-India relations were generally stable and calling for actions conducive to bilateral ties.
The latest development comes even as India and China continue diplomatic engagement on border issues: at their 36th Working Mechanism for Consultation and Coordination (WMCC) meeting on August 6, both sides agreed to continue using diplomatic and military channels to manage outstanding issues and avoid misunderstanding and miscalculation along the Line of Actual Control (LAC).
27 Locations Put On Official Maps
The Union Home Ministry’s announcement is significant because it formally places the 27 locations within India’s official cartographic record. Rather than presenting the exercise simply as a response to Chinese naming, the government said the locations were identified in consultation with Arunachal Pradesh and incorporated with their standard names on Survey of India maps. The stated objective is to make these geographical features easier to identify accurately and improve public awareness about them.
The list spans several categories and geographically sensitive areas of the state. The 21 land locations include Longju, Maja, Bisa, Bara Kundun, Chhota Kundun, Dhan Bari, Pritnagar, Buddhamandir, Jairampur, Teritnagar, Ramnagar, Jaswant Garh, Sagar, Padma, Jyotinagar, Baisakhi, Chhota Ropuk, Bara Ropuk, Shivaji Nagar, Sunpura and Kamlang Nagar.
Four mountain passes Dzo La, Riza La, Pukur La and Thag La have also been included, along with Sambho Sarovar and the Sher-e-Thapa Memorial. The locations cover strategically important districts including Upper Subansiri, Anjaw, Changlang, West Kameng and Lohit.
The choice of locations also gives the announcement historical weight. Thag La, for instance, is associated with the 1962 India-China war and the confrontation around the Namka Chu valley. Jaswant Garh and the Sher-e-Thapa Memorial similarly connect the map with India’s military history along the eastern frontier.
The exercise therefore goes beyond simply standardising names for settlements. By recording settlements, mountain passes, a lake and a war memorial on its official maps, India is reinforcing the geographical record through which it describes and administers the region.
The distinction is important. Putting a place on an official map does not, by itself, alter physical control over disputed territory or settle an international boundary. The India-China boundary remains disputed, and the two countries have different perceptions of parts of the LAC.
What the latest decision does is formally record India’s position through its own national mapping authority. The New Indian Express reported that the move provides uniform legal, administrative and cartographic recognition to the identified locations, while the Home Ministry itself framed the exercise primarily around precise identification and public awareness.
Why Longju Is So Significant
Of the 27 locations, Longju carries particular historical and strategic significance. The village, in the Upper Subansiri sector, became the site of one of the earliest armed confrontations between Indian and Chinese forces in the eastern sector of the disputed boundary. In August 1959, Chinese troops attacked an Indian position at Longju, forcing Indian personnel to withdraw. Historical records show that the confrontation became a major turning point in the deterioration of India-China relations before the 1962 war.
Longju has since remained under Chinese control, while India continues to regard it as falling within its territorial claim. The Arunachal Times reported in July 2026 that Longju remained under Indian administration until 1959 and that India considers it part of Upper Subansiri, while China administers it under Shannan prefecture in the Tibet Autonomous Region. Earlier reporting based on Indian security sources has also described the area as having come under Chinese control after the PLA overran the Assam Rifles post in 1959.
That history makes Longju’s inclusion particularly notable. India is not claiming that the mapping exercise has restored physical control over the village. Instead, the location’s inclusion makes clear that India’s official cartographic record continues to recognise Longju within its territorial claim despite the fact that it is currently administered by China. The distinction between territorial claim and actual control is central to understanding the India-China boundary dispute.
The LAC itself is not an agreed international boundary. It is a line separating areas under the actual control of India and China, while both countries maintain competing territorial claims in several sectors. In Arunachal Pradesh, China claims the entire state as part of what it calls “Zangnan” or “South Tibet”, while India regards Arunachal Pradesh as an integral part of the country. The disagreement therefore involves not just where troops are stationed but also how each country defines, records and describes the territory.
The historical dimension of Longju also demonstrates why border disputes cannot be reduced to a simple question of changing names. A village may carry different names on different maps, but behind those names can lie decades of military confrontation, competing administrative records and unresolved territorial claims. In Longju’s case, the dispute stretches back more than six decades to the 1959 confrontation that preceded the 1962 war.
From Chinese Renaming To India’s Map Response
China’s latest naming campaign is part of a pattern that has unfolded over several years. Beijing first released a list of six renamed locations in Arunachal Pradesh in 2017, followed by another list of 15 places in 2021 and a further list of 11 names in 2023. India has consistently rejected these exercises, arguing that changing names cannot alter the territorial status of Arunachal Pradesh.
In April 2026, China released another batch of standardised names for places in what it calls Zangnan. India objected, describing Beijing’s attempts as the assignment of “fictitious” names and reiterating its position on Arunachal Pradesh. China responded by defending the move.
Chinese Foreign Ministry spokesperson Guo Jiakun said that Zangnan was Chinese territory and that the Chinese government had the sovereign right to issue standard names for places there. At the same time, Guo said China-India relations were generally stable and expressed hope that both sides would work towards actions conducive to bilateral relations.
The competing naming exercises have effectively turned cartography into another arena of the India-China territorial dispute. A place name may appear administrative or cultural on the surface, but when used by a government in official maps and records, it can also communicate a claim over sovereignty and jurisdiction.
India’s decision to formally identify 27 locations on Survey of India maps therefore represents a different form of response. Rather than merely issuing another diplomatic rebuttal to China’s nomenclature, New Delhi has placed its own standard names into the country’s official mapping framework. The move signals that India intends to preserve and publicly document its own territorial position, including in areas where China currently exercises physical control.
At the same time, the timing is noteworthy because India and China are simultaneously attempting to maintain diplomatic mechanisms for managing their differences. On August 6, one day before the mapping announcement, the two countries held the 36th WMCC meeting in New Delhi.
The discussions covered the overall situation along the LAC, boundary delimitation, border management and trans-border cooperation. Both sides agreed to continue using established diplomatic and military channels, including the WMCC and local commander-level meetings, to address outstanding issues and prevent misunderstanding and miscalculation.
This creates a complicated picture of the relationship. On one side, both countries are maintaining communication mechanisms designed to prevent border tensions from escalating. On the other, they continue to take firm positions on territorial claims, including through maps and place names.
There has also been renewed public attention around alleged Chinese activity in Arunachal Pradesh in recent weeks, fuelled in part by social-media posts and claims about alleged incursions. Those claims need to be treated cautiously and separately from the current mapping announcement.
The latest verified reporting does not establish that the 27-location exercise was a response to a newly confirmed Chinese military incursion. Its immediate context is China’s repeated renaming campaign and India’s effort to strengthen its own official cartographic record.
The broader lesson is that the India-China boundary dispute is fought through several channels simultaneously: military deployments, infrastructure, diplomacy, cartography, administration and public messaging. The latest map exercise belongs to that wider contest, but it should not be mistaken for a change in the physical status of the disputed frontier.
The Logical Indian’s Perspective
The decision to formally identify 27 Arunachal Pradesh locations on India’s official maps is understandable as an assertion of the country’s territorial and administrative position, particularly when Beijing continues to use unilateral naming exercises to reinforce its own claims. At the same time, border disputes carry consequences far beyond maps and official statements: they affect communities living near the frontier, soldiers stationed in difficult terrain and millions of ordinary people who can quickly become exposed to misinformation, fear and nationalist hostility.
India’s right to document its territorial position does not need to come at the cost of dialogue, and China’s competing claims should not become a reason for ordinary Indians and Chinese people to view one another with suspicion or hostility. The fact that India and China are still using diplomatic and military channels to discuss the LAC is important because sustained communication is ultimately safer than escalation, while accurate information is far more valuable than viral claims about alleged incursions or territorial losses.
