From Doklam to Galwan: The Changing Rules of Border Competition
Post-Doklam and Galwan clashes, it was very clear that the Line of Actual Control was no longer merely a disputed frontier marked by competing maps and patrols, but now it’s a permanent contest of infrastructure, surveillance, military readiness, diplomacy, and national resilience. From Doklam to Galwan, India has learned that the central challenge from China is not always a dramatic assault across the Himalayas, but it’s the gradual alteration of facts on the ground, which is often below the threshold of open war.
The latest phase of India-China engagement offers cautious reasons for optimism. We know that at the 25th round of Special Representatives talks held in Beijing on 25 August 2026, India and China had agreed on an eight-point consensus covering border management, military communication, boundary negotiations, trans-border rivers, trade and pilgrimage. Yet the agreement is best understood only as a mechanism for managing rivalry and not as proof that the rivalry has ended.
The Doklam confrontation in 2017 had clearly demonstrated that a local dispute in the Bhutan-China-India trijunction could acquire wider consequences because of its proximity to the Siliguri Corridor, which is the narrow land link connecting India’s North-Eastern states with the rest of the country. Thus, India’s decision to physically block the Chinese road construction through Bhutan reflected a clear strategic calculation and a strong stand.
Doklam had clearly exposed the changing character of Chinese border strategy. Infrastructure was not simply a civilian development tool. Roads, tracks, communications networks, and permanent settlements are clearly aimed at improving the PLA’s ability to reinforce contested areas rapidly and sustain itself, dominating the local tactical environment.
Then the crisis in Eastern Ladakh in 2020 made this lesson far more urgent. The Galwan Valley clash in which soldiers from both sides were killed actually destroyed the assumption that earlier confidence-building arrangements alone could preserve peace. The subsequent military face-off brought large-scale troop deployments, including armor, artillery, air power and logistical mobilization to a frontier which was previously managed through patrolling protocols and political restraint. Galwan was, therefore, more than a violent incident. It marked the end of an era where India could no longer assume that economic engagement or diplomatic dialogue would automatically prevent coercive military pressure. The relationship had entered a phase in which peace required credible preparedness.
Sikkim and the Siliguri Corridor: The Strategic Stakes of a Changing Frontier
The Sikkim sector illustrates how this strategic competition is evolving even without a major ground crisis. Historically, parts of this sector were regarded as comparatively stable because the alignment was more clearly understood than in Western Arunachal Pradesh or Eastern Ladakh.
Now that relative stability has weakened because Chinese infrastructure development in Tibet has evidently compressed India’s reaction time. All-weather roads, upgraded airfields, rail extensions towards Nyingchi and the development of “Xiaokang” villages have created a network capable of supporting rapid reinforcement and sustained presence. These settlements combine civilian development with surveillance, communications and logistical functions reflecting a broader civil-military fusion approach. Thus, the result is that in this frontier the distinction between civilian and military infrastructure is increasingly blurred. A village may support population settlement, administrative control and political messaging but also function as a logistical node. A road may be presented as developmental but it retains immediate military utility. This is a strategic competition by construction.
Repeated incidents at locations such as Naku La have also changed the operational atmosphere. Temporary patrol confrontations are now occurring against the background of larger forward deployments, enhanced surveillance and pre-positioned supplies. The danger lies not only in deliberate escalation but also in miscalculation because a patrol encounter can become politically significant when both militaries are operating at heightened alert.
For India, the Sikkim sector is inseparable from the security of the Siliguri Corridor. This, therefore, makes it likely to remain a zone of structured friction, even if both sides avoid a major confrontation in the future.
Infrastructure as Deterrence: India’s Response along the Northern Frontier
India’s ground position today is, however, considerably stronger than it was before Doklam. The most important change has been the accelerated construction of roads, bridges, landing grounds, communication systems and logistics facilities along the northern frontier. Project Swastik has expanded connectivity in Sikkim, including 1412 km of roads and around 80 major bridges. The Chungthang–Lachen axis and the Taram Chu Bridge, which was recently inaugurated after restoration on 26 February 2026, are especially important because they support year-round movement in terrain where winter and monsoon conditions can otherwise isolate the forward areas.
Though China has the geographical advantages on the Tibetan plateau, our infrastructure development reduces the time required for Indian forces to reinforce threatened sectors. So, in military terms, the objective is not merely to reach the frontier, but to sustain combat power there.
This is a significant shift in India’s strategic posture. Strangely, earlier the border infrastructure was often constrained by concerns that improved roads might help the potential adversary. However, after Doklam, followed by the Galwan clash, that caution prevailing in the mindset gave way to urgency. India now recognises that poor connectivity creates vulnerability regardless of whether a crisis occurs.
Thus, while diplomacy worked to reduce immediate tensions, India accelerated its border infrastructure programme to ensure that any future crisis would be met from a position of greater strength. The strategic lesson after 2020 was clear that connectivity is not just developmental but, in reality, it is the core element of deterrence.
By 2024, the Border Roads Organisation (BRO) is known to have completed 111 infrastructure projects at a cost of around ₹3,751 crore. The Union Budget for 2025–26 allocated ₹7,146.50 crore to the BRO, marking a nearly 10 percent increase from the previous year’s estimates. This funding supports the construction and maintenance of roads, bridges and tunnels in difficult terrain along the northern frontier.
In Eastern Ladakh, the Durbuk-Shyok-Daulat Beg Oldi (DS-DBO) road is particularly significant. It runs close to the LAC and provides critical connectivity to India’s northernmost posts, including Daulat Beg Oldi, which is strategically important because of its proximity to the Karakoram Pass and the Depsang sector. Improved road access reduces the time required to move troops, equipment and supplies to forward areas, thereby enhancing operational flexibility.
Tunnels are a key component of India’s infrastructure strategy because they ensure all-weather connectivity in regions where snow, landslides and extreme weather can otherwise isolate forward areas for months. In December 2025, our Defence Minister inaugurated 125 BRO projects, including the Shyok Tunnel on the DS-DBO road in Eastern Ladakh. The strategic effect is twofold. First, it reduces India’s vulnerability to seasonal disruptions that an adversary could potentially exploit. Second, it signals that India can sustain a prolonged presence and, if necessary, a prolonged confrontation along the LAC.
Beyond roads and tunnels, India has invested in bridges, airfields, helipads and logistics nodes along the northern border. In Sikkim and Arunachal Pradesh, new bridges and upgraded roads have improved connectivity to forward areas, mirroring the effort in Ladakh. Advanced landing grounds and helipads enable rapid airlift of troops, casualties and supplies, while improved logistics bases allow for better stockpiling of fuel, ammunition and other essentials.
Infrastructure is only one part of the equation. India is also upgrading surveillance, communications and electronic warfare capabilities along the LAC. This includes space-based surveillance, unmanned aerial systems, ground-based radars and secure communication networks. The objective is to improve situational awareness, detect intrusions earlier and coordinate responses more effectively across the Army, Air Force and paramilitary forces.
India’s air infrastructure improvements along the northern frontier have been substantial with the upgradation of forward airfields like Daulat Beg Oldi (DBO), Nyoma, Fukche and Thoise in Ladakh. These have been modernised with extended runways, hardened shelters, fuel storage and all-weather operational capabilities. These improvements, therefore, now allow India to deploy fighter aircraft, transport planes and helicopters closer to the LAC. However, significant challenges still remain and miles yet to be covered.
China’s advantages in altitude, infrastructure density and aircraft numbers mean that India must continue to invest heavily not only in air-power modernisation and infrastructure development to maintain a credible deterrent posture in this region but also in parallel, build a strong naval force to dominate the Indian Ocean Region from where the bulk of China’s trade passes through. Creating a Maritime Theatre Command, therefore, should be a priority over other theatre commands.
Disengagement Without Resolution: The Unfinished Contest Along the LAC
The disengagement agreements at Depsang and Demchok in October 2024 did not end the India-China border dispute but they did alter the military and political dynamics along the LAC in Eastern Ladakh. After more than four years of a tense standoff that began in 2020, these agreements restored patrolling access to traditional areas, reduced the immediate risk of accidental clashes and created a narrow window for diplomatic repair.
The removal of “blocking positions” reduced the day-to-day friction that had characterised the standoff. It also lowered the probability that a routine patrol encounter would escalate into a larger crisis. Post this agreement, the Defence Ministry described the LAC situation as “stable but sensitive,” acknowledging that the underlying dispute and strategic competition persisted even as specific flashpoints are managed.
At the same time, the disengagement agreements underscored that stability now depended less on trust and more on verified arrangements, infrastructure and deterrence. At the LAC, therefore, we strongly believe that restraint and strength are not opposites but they are the two halves of credible deterrence.
The LAC has now turned into a multi-domain battlefield. China’s pressure is not limited to troop movements or physical intrusions but also includes cartographic claims and administrative renaming, besides cyber operations, electronic interference, information warfare, economic coercion and what our late General Bipin Rawat, the CDS then, had described as “salami slicing.” Cartographic aggression in Arunachal Pradesh is part of this wider effort. Maps, official names and administrative claims seek to normalise a political narrative in which disputed territory is gradually presented as settled Chinese space. Such actions may appear symbolic but they are intended to influence international perceptions and future negotiations.
Recently, China objected to our renaming of a few places in Ladakh, claiming them as its territory. Well, the world at large must ask China whether Tibet is historically its territory or was annexed by the CPC with the help of its PLA. India must, therefore, defend not only territory but also the information environment surrounding that territory.
The LAC will remain contested because the underlying boundary dispute has not been resolved and because China’s infrastructure-led strategy continues to generate pressure. Yet, India is better prepared now to hit back than it was over a decade ago. Post-Doklam and Galwan clashes, India stands in a harder but more realistic position. It is no longer relying on the hope that unresolved differences can be insulated from the wider relationship. India is also not seeking confrontation for its own sake. India’s approach is increasingly one of calibrated firmness, that is, maintain dialogue, preserve military readiness, improve border infrastructure and resist unilateral attempts to alter the status quo.
The Long Game in the Himalayas: China’s Strategic Footprint and India’s Response
We must see from a wider prism that China’s infrastructure development along the LAC is not merely a developmental programme. It is a deliberate, multi-domain strategy designed to reshape the Himalayan frontier in ways that enhance Beijing’s military reach, consolidate territorial claims and create long-term leverage over India. China’s plans against India have been planned and implemented at various layerssince over several decades. From Theaterisation of Forces, large scale infrastructure developments to include roads and railways to airfields, dams and “Xiaokang” border villages, China has been transforming the Tibetan plateau into a forward operating base capable of sustaining prolonged military presence and rapid escalation. Approximately 72 per cent of these villages are located near the LAC in India’s North-Eastern sector with 90 per cent of those facing Arunachal Pradesh. Smaller clusters exist in sectors facing Sikkim, Uttarakhand and Ladakh.In this entire range of activities, China has cleverly and quietly taken a lead of at least 15-20 years.
China is currently rapidly relocating the Tibetan population into frontier settlements under its border-village and poverty-alleviation programmes. Official figures cited by researchers indicate that 241,835 people were “involved” in the TAR border-village programme, while reports also refer to plans to move tens of thousands of border residents into 628 villages. For India, the danger is not that Tibetan civilians will suddenly “march across” the LAC but it is subtler, that is, a state-sponsored population architecture that entrenches Chinese control opposite Arunachal Pradesh compressing India’s strategic depth and making future incursions look like routine local administration.
India’s Response
India’s response, though delayed earlier, has, however, seen significant progress and implementation post-2014, for which the current dispensation must be credited. Government attention in terms of planning, resource outlay, and project implementation towards Theaterisation and modernization of Defense Forces for a robust response across high-altitude-based Northern borders, as well as focused infrastructure development, is appreciable. A similar planned push and implementation is required in developing and establishing our own Border villages all along the LAC. This is a challenge in a democratic setup since it involves convincing groups of people to move ahead, set up a daily routine, and remain permanently established. This requires pre-planned and implemented essential logistical support, electricity, roads, and sustainable daily essential supplies to such new villages. However, continuous government-monitored support, which is feasible to be implemented by the current Nationalistic govt, is a prerequisite. Identifying such village locations to extend our ‘civilian reach’ closer to the LAC with concerned State Govts of Arunachal, Sikkim, Uttarakhand, HP, Ladakh and rolling out an actionable plan with clear timelines and phases with committed financial outlays is an urgency and way forward.
Finally
India has already seen in the North-East how porous borders, ethnic linkages and weak documentation can produce decades-long demographic and security pressure. Migration from Myanmar, especially Chin-State movement into Mizoram, has continued since the 1960s. The 2021 Myanmar coup intensified the flow and it is estimated that nearly 70,000 refugees entered India after the coup, including more than 40,000 in Mizoram and over 8,000 in Manipur. These movements have strained local resources, identity politics, administration and border management.
The lesson is clear that demographic change at a frontier rarely arrives as an invasion. It slowly accumulates through displacement, kinship networks, economic necessity, weak enforcement and political vacuums until it becomes a permanent strategic reality.
Thus, by resettling the Tibetan population close to the LAC across Arunachal Pradesh, China is attempting to make the LAC look less like a disputed line and more like an ordinary Chinese provincial frontier populated, connected, policed and defensible. The hidden long-term agenda of China is to infuse demographic invasion into Arunachal Pradesh over a few decades and gradually influence the hearts and minds of our young, coming-up generation there to begin to feel that they are more Tibetan than Indian.
