The Chittagong Corridor vs Siliguri debate is gaining more traction in 2026. While India’s 22km “Chicken’s Neck” has long been associated as a regional vulnerability by radical elements and interim leader Muhammad Yunus, a new “Mirror Neck” counter-narrative has emerged as the Bangladesh general election cycle begins.
The Siliguri Corridor, which is India’s 22km “Chicken’s Neck” and lies sandwiched between Nepal, Bhutan, Bangladesh, and China.
The idea as highlighted by Assam Chief Minister Himanta Biswa Sarma, who mentioned that Bangladesh has its own “chicken necks” which, according to him, are more vulnerable than India’s thin corridor.
Bangladesh’s economic lifeline: The 28 km chokehold
The Chittagong Corridor appears to be the most dangerous of these ‘mirror’ vulnerabilities. Dhaka has often cited India’s connection to its Seven Sisters through the thin land strip. Now military experts highlight that the economic capital of Dhaka, namely Chittagong, is connected to the rest of Bangladesh via a land strip merely 28km wide.
• The South Tripura Factor – A narrow corridor squeezed between the Indian state of Tripura and the Bay of Bengal.
• The logic is if the 28-kilometer section was disrupted, over 80% of Bangladesh’s trade would be cut off from the political capital in Dhaka, posing a strategic risk.
The 80km Northern Vulnerability: The Rangpur Stretch
The 80 km North Bangladesh Corridor is the second mirror neck. The corridor from Dakshin Dinajpur to the South West Garo Hills is the only terrestrial connection for the entire Rangpur Division.
• The narrowest point along the Karatoya River could become a natural boundary limiting the access of the northern division to the mainland in conflict.
| Feature | Siliguri Corridor (India) | Chittagong Corridor (Bangladesh) |
| Narrowest Point | 22 km | 28 km |
| Strategic Role | Link to Northeast India | Link to Economic Hub (Chittagong) |
| Primary Risk | Military isolation | 80% Trade Severance |
Why the mirror rhetoric is spiking in 2026
1. In February 2026, as the Awami League is banned and the BNP seeks to recover their lost power in Bangladesh, rhetoric regarding sovereignty and Indian domination is very high.
2. The Lalmonirhat airbase, which is only 135km away from Siliguri Corridor used by India; has raised concerns in India where it believes that Dhaka is being reminded of mirror vulnerabilities.
3. The Yunus Doctrine: Interim chief Muhammad Yunus has said the Indian Northeast is landlocked and that Bangladesh is the ocean’s guardian for it. N reaction, Assam CM Himanta Biswa Sarma, has given currency to “Mirror Chicken Neck” as a counter-deterrent.
According to security expert, S Sengupta raising the chicken’s neck issues is a luxury that neither India nor Bangladesh can afford. According to him, while India may be worried about Siliguri, but Bangladesh has to think on two separate necks.
Security expert S Sengupta sees justification in the Sarma views. “While India worries about Siliguri Corridor as the Bangladesh side often tries to build pressure on New Delhi, highlighting India’s vulnerabilities, Dhaka has more to worry. Bangladesh will be effectively three separate pieces that are disconnected. It has actually two ‘necks’ and once you cut them, the country disintegrates,” he said.
