What Happened
- Wolfgang Petermann, a US Army official assigned to the Defence Intelligence Agency (DIA), has argued that India's strained ties with Bangladesh under Chief Adviser Muhammad Yunus create the conditions for a strategic "three-front encirclement" of India.
- The analysis identifies three simultaneous pressure vectors: the Line of Actual Control (LAC) with China in the north and northeast; the Line of Control (LoC) with Pakistan in the west; and now a potentially hostile Bangladesh in the east — closing off India's eastern flank.
- Petermann notes this conundrum could also affect US strategic calculations around Taiwan, as India's resources and attention are tied down in South Asia.
- Bangladesh's post-Hasina pivot toward China has included Chief Adviser Yunus calling Bangladesh "the only guardian of the ocean" for India's landlocked northeastern states and positioning Dhaka as an "extension of the Chinese economy" during a March 2025 visit to Beijing.

The Siliguri Corridor: India's "Chicken's Neck"
The Siliguri Corridor is a narrow strip of land — approximately 20–25 km wide at its narrowest point — connecting India's eight northeastern states (Arunachal Pradesh, Assam, Meghalaya, Mizoram, Manipur, Nagaland, Tripura, Sikkim) to the Indian mainland. Flanked by Nepal to the north, Bhutan to the northeast, and Bangladesh to the south, it represents India's most critical and most vulnerable land connectivity chokepoint. Any military or political disruption here could sever ~50 million people and the northeastern states from the rest of India. China could reach the corridor with an advance of approximately 130 km from its current positions.
- Siliguri Corridor width: 20–25 km at narrowest
- States connected: 8 northeastern states (~50 million people)
- Flanking countries: Nepal (north), Bhutan (northeast), Bangladesh (south)
- Distance: Chinese forces could reach corridor in ~130 km advance
- Lalmonirhat Airbase: WWII-era airbase in northern Bangladesh, ~135 km from Siliguri, reportedly being revived with Chinese involvement
- India's response: Deployment of Rafale jets, BrahMos missiles; underground railway tunnels under construction
Connection to this news: A hostile Bangladesh aligned with China would transform the Siliguri Corridor from a narrow but secure passage into a genuinely exposed flank — the "three-front" scenario described by the US official.
India's Neighbourhood First Policy and Its Limitations
"Neighbourhood First" is India's foreign policy priority since 2014 under the Modi government, placing South Asian neighbours at the centre of India's diplomatic and development outreach. It aims to build interdependence through connectivity (transport corridors, energy grids), trade, and people-to-people ties, making India an indispensable partner for the region. The policy has faced structural challenges: India's neighbours have often leveraged Beijing as a counterweight when dissatisfied with New Delhi, a dynamic known as "hedging." Bangladesh under Sheikh Hasina (1996–2001, 2009–2024) was considered India's closest neighbour, but the August 2024 political transition reversed this alignment sharply.
- Neighbourhood First policy announced: 2014, first declared at PM Modi's swearing-in ceremony (SAARC leaders invited)
- India-Bangladesh relationship under Hasina: Joint border management, land boundary agreement (2015), connectivity projects
- Bangladesh under Yunus (from August 2024): Post-Hasina caretaker government; sharp pivot toward China and Pakistan
- Bangladesh-China 10-year strategic partnership: Bangladesh secured $2.1 billion in investments/grants during Yunus's March 2025 Beijing visit; total Chinese investment ~$42 billion
- SAARC: South Asian Association for Regional Cooperation; 8 members; headquarters: Kathmandu
Connection to this news: The three-front encirclement analysis is a direct consequence of Neighbourhood First policy failure — India's inability to maintain Bangladesh within its strategic orbit has created the eastern vulnerability.
China's String of Pearls and Encirclement Strategy
China's "String of Pearls" is a geostrategic concept describing China's effort to establish a network of commercial and military access points across the Indian Ocean Region — from the South China Sea through the Strait of Malacca, across the Bay of Bengal, to the Arabian Sea. Each "pearl" provides logistics, intelligence, and potential military basing for the Chinese Navy. When combined with land-based pressure from Tibet/Xinjiang (LAC) and maritime encirclement (Indian Ocean), China's strategy aims to constrain India's strategic options from multiple directions simultaneously. Bangladesh's alignment with China adds a new "pearl" directly adjacent to India's eastern heartland.
- String of Pearls locations: Gwadar (Pakistan), Hambantota (Sri Lanka), Chittagong (Bangladesh), Kyaukpyu (Myanmar), Djibouti (Africa)
- China-Pakistan Economic Corridor (CPEC): ~$62 billion BRI project; connects Kashgar (China) to Gwadar (Pakistan)
- Hambantota Port: Sri Lanka leased to China for 99 years in 2017
- Mongla Port (Bangladesh): China is modernising Bangladesh's second-largest seaport
- Teesta River project: China advancing water management project in Bangladesh — a major diplomatic flashpoint with India
Connection to this news: Bangladesh's growing infrastructure dependence on China, plus the Lalmonirhat airbase revival, fits the String of Pearls logic — bringing Chinese strategic assets to within 135 km of India's most vulnerable geographic chokepoint.
India's Internal Security Implications: The Northeast
India's northeastern states have historically been theatres of insurgency — groups like ULFA (United Liberation Front of Asom), NSCN (Nagaland), and various Manipuri outfits operated across borders with Myanmar and Bangladesh. The porous borders were channels for arms trafficking, narcotics, and militant safe havens. A hostile Bangladesh would complicate India's counter-insurgency operations, potentially reversing decades of progress. The Free Movement Regime (FMR) along the India-Myanmar border, recently suspended by India in 2023, and border fencing projects underscore New Delhi's sensitivity to eastern border security.
- India-Bangladesh border length: ~4,156 km; partially fenced
- Border Security Force (BSF) jurisdiction: India-Bangladesh and India-Pakistan borders
- ULFA (United Liberation Front of Asom): founded 1979; peace talks with India ongoing
- India-Myanmar FMR: suspended January 2024 by India; border fencing accelerated
- Bangladesh-India land boundary settlement: 2015 Land Boundary Agreement resolved 162 enclaves
Connection to this news: A Bangladesh that hosts Chinese military assets and adopts a hostile stance toward India would create a security vacuum on India's eastern border, potentially re-energising insurgency networks in the Northeast.
