A Border With No Line: The Thaw That Never Reached the Ground

The easiest assumption to make about India and China in the autumn of 2026 was that the worst was behind them. The supporting evidence looked solid. Prime Minister Narendra Modi and President Xi Jinping had met at the BRICS summit in Kazan in October 2024, again at the SCO summit in Tianjin in August 2025, and once more at the BRICS summit in New Delhi in 2026. The Defense Ministry’s annual report for 2025-26 recorded a significant reduction in Chinese troop deployment along the frontier during 2025. [2]. On those four data points, a reasonable person could have concluded that the Himalayan dispute had been parked. That conclusion was wrong. The correction did not arrive as a satellite image or a leaked cable; it arrived from a police chief with a border force, and it exposed a distinction the summits had blurred — the quiet had settled on the capitals, not on the ground.

Two Armies On An Undrawn Line

Indo-Tibetan Border Police Director General Shatrujeet Kapur put the correction on the record. He told reporters that Indian and Chinese troops had confronted each other at several locations along the de facto border in Arunachal Pradesh, and that the confrontation had not ended. [1] His wording left no room for a diplomatic reading: “In the past few days, a situation arose where a face-off happened (with Chinese troops) at various locations in Arunachal and it still continues.” [1] He then added a second judgment that reached further than the incident itself: “It may be difficult to counter China by conventional means because their PLA and BDR (Border Defense Regiment) have gone way ahead with investment and modernization.” [1] That is a statement about capability, not about a patrol that went wrong. It came from the official responsible for a stretch of the frontier, not from a think tank. A face-off, in other words, is being reported by the same man who believes the balance on the ground has moved.

The reported geography is narrow and measurable. Since late July 2026, People’s Liberation Army troops have faced off with Indian forces near Asaphila and Taksing in the Upper Subansiri district of Arunachal Pradesh. Tents have been pitched within 6-7 km of India’s perception of the Line of Actual Control. That distance is the detail that matters, because it is measured against India’s own reading of the line rather than against a boundary both governments accept. The Line of Actual Control is the de facto border that separates Indian- and Chinese-controlled territory; troops from both sides patrol ground they each regard as their own, which is how encounters happen without anyone deciding to start one. No clash has been described as violent by either army. The Indian government has not disclosed the locations or the circumstances, which leaves the most basic question — has anything on the ground actually changed? — without an official answer.

Two governments then gave two accounts of the same events, and the distance between them is the substance of the dispute. External Affairs Ministry spokesperson Randhir Jaiswal placed the cause in Chinese behaviour: “As we have noted in the past, the situation in the India-China border areas gets disturbed from time to time when Chinese forces diverge from established patrolling patterns.” Chinese Foreign Ministry spokesperson Guo Jiakun rejected that framing, describing Chinese troops as conducting “normal patrols” and as strictly abiding by bilateral agreements. Both statements can hold at once only if the two governments disagree about where patrolling is supposed to run — which is the dispute itself, not a misunderstanding about it. On the Indian side, Arunachal Pradesh Chief Minister Pema Khandu acknowledged border transgressions while calling the situation along the border normal and noting that such incidents were not new. He also named the two facts that summitry has not touched: the border is not properly demarcated, and China does not recognize the McMahon Line, drawn by the British Empire in 1914 to separate Arunachal Pradesh from Tibet.

The arithmetic explains why the friction keeps returning. India puts the de facto border at 3,488 kilometres, or 2,167 miles; China says the line is shorter. [1]. The two countries have held 25 rounds of talks between their Special Representatives since 2003 — the envoys each government appoints to the boundary question — and have still not reached a settlement. Gautam Bambawale, a former Indian ambassador to China, reduced the mechanism to a single sentence: “There is a very simple reason — because there is no agreed line between the two.” The stakes are set by what happened the last time the mechanism failed. In June 2020, a clash in the Galwan River valley in eastern Ladakh killed 20 Indian soldiers and four Chinese troops, and both countries then massed tens of thousands of soldiers along an undemarcated Himalayan frontier. [1]. That is the baseline against which a tent 6-7 km inside one side’s reading of the line has to be judged.

Why the Eastern Sector Got Crowded

Aravind Yelery, a China expert at Jawaharlal Nehru University, separates the permanent from the new. Friction, in his account, is built into the arrangement: “Both sides patrol a contested LAC, so friction is built into the arrangement.” What has changed is where Beijing is looking. “What is new is China’s intensified focus on the eastern sector. Since announcing the 60,000-megawatt Medog hydropower project in Tibet, Beijing has poured infrastructure, troops, engineers and machinery into the area.” The figure is not decorative: a 60,000-megawatt project is a national-scale undertaking, and the build-out around it is what turned a remote stretch of the frontier into a place where patrols now meet. He describes the line itself as “not a thin line but a deep zone of overlapping claims where patrols inevitably meet,” and he expects face-offs to continue until diplomacy produces concrete arrangements on the ground.

The paradox is that the same period produced fewer Chinese soldiers along the frontier. India’s Defense Ministry, in its annual report for 2025-26, stated: “The year 2025 witnessed significant reduction in deployment of People’s Liberation Army (PLA) Force opposite Northern Borders, with 10 Combined Arms Brigade size forces each deployed in areas along the LAC and in traditional training areas.” The report credited engagement at the political, diplomatic and military levels with “positive developments along the northern border, leading to stability.” India published no figure for its own deployment, saying only that the army’s posture in all sectors along the LAC remained “robust, well poised, and prepared to deal with any emerging contingency.” It also highlighted accelerated construction of tunnels, roads and all-weather infrastructure in the Himalayas, which it called critical for the rapid movement of troops, equipment and supplies. Retired Brigadier Arun Sahgal, who directs the Forum for Strategic Initiatives in New Delhi, drew the conclusion: “Maintaining a strong dissuasive posture and preparedness along the borders is an imperative. We cannot scale down our defenses irrespective of troop numbers.” Fewer men, in other words, is not the same fact as less capacity.

Alongside the tents, both governments have been fighting over names. China’s Civil Affairs Ministry has released Chinese names for locations in Arunachal Pradesh periodically since 2017, with the most recent set issued in April. In August, India formally identified 27 places and features in the state by their standard Indian names on the official map. Among them is Longju, a border village controlled by China since 1959 but inside the Indian claim line. The Ministry of Home Affairs described the purpose in its own words: “Identifying them formally on the Survey of India map of Arunachal Pradesh is aimed at facilitating their accurate recognition and better awareness among the public at large.” Beijing calls the state Zangnan, or South Tibet, and claims it as Chinese territory. New Delhi rejects that claim and describes Arunachal Pradesh as an “inalienable and integral part of India.” In effect, a name on a map is a cheap way to hold a position that would be expensive to hold with troops, and both sides are using it.

The diplomatic ladder meant to manage all of this has been climbed steadily. The October 2024 Modi-Xi meeting in Russia produced an agreement that helped end the military standoff in eastern Ladakh. [2]. The August 2025 meeting in Tianjin and the 2026 BRICS summit in New Delhi — Xi’s first trip to India in seven years — were accompanied by the restoration of some direct flights and an easing of restrictions on travel and economic exchange. The working level moved as well: National Security Advisor Ajit Doval met Chinese Foreign Minister Wang Yi in Beijing on August 25, and Corps Commander-level talks were held on September 6 at the Wacha-Damai border meeting point on the Indian side. Wacha is India’s easternmost border personnel meeting point, located in the Kibithoo sector of Arunachal Pradesh, and Indian troops remain deployed there in large numbers to prevent any escalation. Yelery’s verdict on the ladder is blunt: “A wide gap separates the leaders’ promises from the measures that would prevent a repeat of 2020, namely disengagement and mutual restraint.”

What New Delhi Has Not Disclosed

The strongest argument for restraint in reading the face-offs comes from a scholar who refuses to fill the gap. Alka Acharya, director of the Institute of Chinese Studies in New Delhi, notes that the government has described the incidents as face-offs but has not indicated that Chinese troops have taken control of Indian territory. Her question is not why clashes recur but what these ones are: “The question is what is the nature of the so-called ‘clashes’… not why the clashes are happening again? Any opinion on this latest kerfuffle would at best be conjecture without any definitive evidence.” She places the events in a longer series, pointing out that border incidents have occurred regularly over the past decade and a half despite political and diplomatic negotiation. The unresolved dispute, in her reading, will keep sustaining distrust and constraining the wider relationship. A face-off, on that account, is the normal output of an abnormal arrangement.

Ashok Kantha, another former Indian ambassador to China, supplies the test that would settle the question if the facts were public. Transgressions in the eastern sector are not new, he notes, but location and extent decide the meaning. “If the Chinese have now made deeper intrusions on our side of the LAC, or established a presence in new areas, or expanded their existing presence, that would be a serious development,” he said. He then attached a legal consequence to that condition: “Any such transgression would be in complete violation of several border-related agreements India and China have signed (1993, 1996, 2005, 2012 and 2013). In these, both sides committed to respect and strictly observe the LAC, and not to alter the status quo.” Five agreements across two decades do not prevent an incident. They define the point at which an incident becomes a breach.

The domestic argument has already priced the ambiguity. Congress general secretary Jairam Ramesh, posting on X about the face-offs confirmed by the border police chief, wrote: “On this there has been a deafening silence from the PM and his establishment.” Congress president Mallikarjun Kharge called the developments “deeply alarming” and demanded answers from Modi on national security, on economic ties with China, and on what repeated diplomatic engagements had actually delivered. The opposition’s charge is that the ruling BJP is “rationalizing” Chinese actions instead of asserting India’s position — a criticism aimed squarely at Khandu’s description of the situation as normal. Two readings are now on the table: routine patrol friction, or encroachment that has not been admitted.

The caution is therefore symmetrical, and it is the reason the missing details matter more than the rhetoric. If a face-off is treated as routine while it is in fact an expansion of presence, the status quo shifts quietly and Kantha’s condition is met without anyone being required to answer for it. If every patrol encounter is treated as a rupture, the diplomatic gains of Kazan, Tianjin and New Delhi are spent on incidents that neither army has described as violent, and the agreements of 1993 through 2013 lose their value as a shared reference point. Those watching are specific rather than abstract: a border police chief who chose to speak publicly about a continuing face-off, an opposition that has already asked its questions in public, and two publics that will judge any thaw by what happens 6-7 km from a line neither government agrees on. Until New Delhi publishes where the tents stand and what changed, Acharya’s standard holds — anything firmer than conjecture is not yet available.
