Geography’s Curse: India’s Vulnerable ‘Chicken’s Neck’
The Siliguri Corridor is a terrifyingly vulnerable artery in India’s geography.
By Ankit Panda

If you’ve been following The Pulse here at The Diplomat recently, you may have noted a few recent pieces (including one by yours truly) on India’s North-Eastern states. In any discussion of the governance problems or border issues in India’s North-East, a commonly mentioned word is “isolation.” The North-Eastern states are politically and geographically distant from New Delhi, and certain parts of the region share more in common culturally with Burma than they do with Punjab, or even West Bengal. A quirk of South Asian political geography has made it quite challenging for New Delhi to effectively integrate the North-Eastern states: the Siliguri Corridor.

Like most of the borders in South Asia, the Siliguri Corridor – known also as the “Chicken’s Neck”– is a cartographic relic of the British decolonization process. As the British Empire withdrew and partitioned British India along religious lines to create the modern states of India and Pakistan (which was then divided into East and West Pakistan), it drew the lines that lead to the Siliguri in an attempt to maintain contiguity between Bengal and Assam. The creation of East Pakistan (which became Bangladesh in 1971) along religious lines necessitated the awkward choke point in India’s contemporary geography. The Siliguri, at its slimmest point, puts less than a marathon’s distance between the Bangladeshi and Nepalese borders (14 miles).

All land trade between North-East India’s 40 million denizens and the rest of the country traverses the Siliguri owing to the lack of a free-trade agreement between India and Bangladesh. In 2002, Nepal, Bhutan, and Bangladesh joined India in discussing a proposal to create a free-trade agreement that would have facilitated the movement of goods across the Siliguri corridor, but no such agreement has been established. Further reinforcing the strategic precariousness of the region is the fact that a single-line railway is all that carries rail-based freight across the Siliguri. The harsh topography of the region makes the railway and roads subject to damage from frequent landslides and natural disaster; India’s North-East is known for its record-breaking levels of rainfall.

As if natural disasters were not enough to send the Siliguri to the top of the list of India’s strategic anxieties, the corridor has a complex and troubled political history. The situation has somewhat improved since the pre-1971 era, when icy relations with China in the north and East Pakistan meant that the region was a constant source of cross-border tension. Since the 1962 war with China, Indian strategists have envisioned a future scenario where "the Chinese may simply bypass and drop Special Forces to choke vulnerable Siliguri Corridor and cut off the Northeast.” China’s diplomacy with Bhutan gives reason to take this possibility seriously; in 1996, China began a concerted diplomatic effort to yield a border claim with Bhutan in exchange for the Doklam Plateau. The territorial swap with Bhutan would place in China’s hands the key to India’s choke point in the Siliguri.

India’s fortunes in the Siliguri were slightly ameliorated when the tiny monarchy of Sikkim – situated just north of the Siliguri, between Nepal, China, and Bhutan – merged with India in 1975 to become its second-smallest state. Sikkim had long been a subject of controversy between India and China. In the early 2000s, China refused to acknowledge Sikkim as part of India, maintaining that it was an independent state. The decision to do so was sparked by a controversy around the 17th Karmapa of the Black Hat branch of Tibetan Buddhism. Nevertheless, in 2003, China granted de facto recognition of Sikkim as a part of India by ceasing to list it as a separate state on its official documents and maps.

In acknowledgement of its importance to India’s national security, the state maintains a heavy patrol presence in the Siliguri region. The Indian Army, the Assam Rifles, the Border Security Force, and the West Bengal Police all patrol the region. India’s Research and Analysis Wing (RAW) is known to closely observe Nepalese, Bhutanese, and Bangladeshi activity in the region as well. Among other issues, the Siliguri has been vulnerable to illegal Bangladeshi immigration into India. Certain analysts have also speculated that Pakistan’s Inter-Services Intelligence (ISI) has attempted to exploit the Siliguri via Nepal-based insurgents.

The Siliguri Corridor is a terrifyingly vulnerable artery in India’s geography. For Indians in the North-East, every look at a map is a sobering reminder of just how fragile their physical and economic tether to the rest of the country remains. Unlike so many of the problems India faces, the Siliguri Corridor’s vulnerability is a cruel endowment of political geography and essentially one it is stuck with. On the bright side, the current level of strategic vulnerability is far lower than it was in the past and can be further moderated with the establishment of a free-trade agreement between the states bordering the Siliguri.​

India fortifies Chicken's Neck: 3 new garrisons set up on Bangladesh border

India has fortified its eastern border by establishing three new military garrisons along the Indo-Bangladesh frontier to secure the strategic Siliguri Corridor amid shifting regional alliances. This move aims to enhance surveillance and rapid response capabilities in a sensitive area connecting mainland India to its northeast states.

India sets up three new garrisons on Bangladesh border, bolstering chicken’s neck

India has strengthened its eastern frontier by setting up three new fully operational military garrisons along the Indo-Bangladesh border, at Bamuni (near Dhubri), Kishanganj, and Chopra, to secure the strategic Siliguri Corridor, commonly known as the “Chicken’s Neck”.

According to top intelligence sources, the move is part of a broader plan to plug tactical gaps, enhance surveillance, and boost rapid-response capabilities in one of India’s most sensitive regions.

The Siliguri Corridor, a 22-kilometre-wide strip in North Bengal, connects the rest of India with its seven northeastern states and lies sandwiched between Nepal, Bhutan, Bangladesh, and China.

INDIA ON GUARD AS DHAKA REORIENTS POLICY

The development comes amid reports of increased engagement between Bangladesh’s interim Chief Adviser Muhammad Yunus and Pakistan’s military establishment, including a recent meeting with Pakistan’s Joint Chiefs of Staff Chairman General Sahir Shamshad Mirza, reportedly to discuss connectivity and defence cooperation.

Since Yunus took charge following former Prime Minister Sheikh Hasina’s ouster, Bangladesh’s policy direction has undergone a marked shift, with overtures to China for investments and a reset of ties with Pakistan. Intelligence assessments describe this as part of a strategic attempt to “reshape the power balance” in the eastern neighbourhood, potentially affecting the security of the Siliguri Corridor.

‘CHICKEN’S NECK IS OUR STRONGEST LINK’

Contrary to perceptions of vulnerability, senior Indian military officials have emphasised that the region is India’s “strongest defence corridor.”

An Army source said, “The Siliguri corridor is under multi-layered security cover. The new garrisons will enhance our quick mobility, logistics, and real-time intelligence integration.”

Earlier, the Indian Army Chief had remarked, “As far as the Chicken’s Neck is concerned, I see it from a different perspective. It is our strongest region because our entire force deployed in West Bengal, Sikkim and the Northeast can be mobilised there together.”

TRISHAKTI CORPS LEADS SECURITY OF THE CORRIDOR

The Trishakti Corps (33 Corps), headquartered at Sukna near Siliguri, oversees the corridor’s defence. The formation routinely conducts combat and live-fire exercises, including with T-90 tanks, to maintain readiness in high-altitude and riverine terrain.

The corridor’s aerial security is bolstered by the Rafale fighter jets deployed at the Hashimara Airbase in West Bengal, alongside MiG variants and a BrahMos missile regiment, ensuring both offensive and deterrence capability.

LAYERED AIR DEFENCE NETWORK

India has also deployed an advanced triad of air defence systems in the region, the S-400 surface-to-air missiles sourced from Russia, the MRSAM system developed jointly by DRDO and Israel, and the indigenous Aakash missile system. Together, they provide overlapping coverage against aerial and missile threats from the east and northeast.

The S-400 system in the region is specifically meant to deter incursions by Chinese or hostile aircraft into Indian airspace. The Defence Ministry has also recently approved Rs 8,160 crore for two additional regiments of the Akash-Advanced system, featuring new seeker technology and 360-degree engagement capability.

BHAIRAV BATTALIONS AND ASHNI PLATOONS

Following Operation Sindoor, the Indian Army has enhanced its drone warfare capability, creating Ashni platoons with FPV and kamikaze drones, and Bhairav battalions equipped for precision strikes.

Officials said these units are designed for rapid deployment and close integration with ground combat teams.

INDIA’S EVOLVING STRATEGY

With China’s growing footprint in Bangladesh through the Belt and Road Initiative (BRI) and Dhaka’s new overtures to Beijing and Islamabad, Indian agencies view the developments as a potential challenge to regional stability.

“India is alert and has factored in every emerging dynamic,” said a senior military planner. “We are not reacting; we are reinforcing.”

The government’s recent infrastructure and deployment drive, from Rafale squadrons to BrahMos regiments, reflects a deliberate shift from deterrence to dominance in the east.​

BSF installs 12-feet-high fencing at Siliguri corridor

New Age Desk 08 January, 2026, 00:36

India’s Border Security Force has installed newly designed border fencing system in almost 75 per cent of the Siliguri Corridor region, Indian newspaper The Tribune reported.

The report published on the newspaper’s website on January 6, referring to BSF officials, says that the upgraded 12-feet-high new design fencing has been erected in the sensitive region, backed with powerful cameras and enhanced area domination plans.


Referring to unnamed sources, the report mentions that lots of efforts were being made to secure the Siliguri Corridor region, which borders Bangladesh and the new design fencing has been erected in 75 per cent of the region. Pan-tilt-zoom cameras have also been installed along the border, which provide live feeds.

Earlier, Indian media reported that India had fortified its most vulnerable but strategically important stretch, the Siliguri

Corridor, which is also known as the Chicken’s Neck, by deploying Rafale fighter jets and Russian-made S-400 air defence system.

The 20–22km-wide corridor is India’s only land link to its north-eastern states and sits at the crossroads of Bangladesh, Nepal, Bhutan and China.​

You mean all other neighbors of India look for cutting the peace into pieces.:p

Correct but their ambitions don't match with their capabilities. Now look at BD. They don't have the capability to sustain a wR against India for even half of the day yet it dreams to capture 7 sisters. This is the high time to change geography of BD. Atleast widen Chicken neck by 200 k.m.
