The trilateral meeting held on June 19 in Kunming between China, Pakistan, and Bangladesh may have appeared routine on the surface, but its implications are far from ordinary. For the first time since independence, India faces a coordinated and institution alized alignment among three of its most consequential neigh borsan emerging triangle that carries profound strategic con- sequences, particularly for the nation’s northeastern frontier.

This is not just a matter of shifting diplomatic rhetoric. The formal establishment of a joint working group among Beijing, Islamabad, and Dhaka covering cooperation in trade, defense, investment, and maritime strategy marks the transformation of an abstract concern into a concrete geopolit- ical challenge.

This strategic triangulation coincides with political uncertainty in Bangladesh, where mounting pressure surrounds interim leader Muhammad Yunus ahead of anticipated elections. At the heart of this emerging threat lies the precarious Siliguri Corridor, India’s narrow and vulnerable link to its northeastern states.

Often dubbed the “chicken’s neck,” this corridor has long been seen as India’s Achilles’ heel. But what was once a theoretical vulnerability has now morphed into an operational concern. Yunus’s provocative statement during his March 2025 visit to China that India’s seven northeastern states can access the ocean only via Bangladesh, positioning his country as the “sole guardian” of the Indian Ocean in the region was not merely rhetorical flourish.

It marked a deliberate shift in Bangladesh’s strategic posture. The reported Chinese proposal to construct an airbase in Lal monirhat, a Bangladeshi district just 20 kilometers from the Indian border, with Pakistan set to participate as a subcontractor, brings this threat uncomfort ably close to home.

Such a development would place potential adversaries within direct strik- ing distance of India’s most frag- ile military and economic access point to its northeast. This tightening strategic triangle is the result of long-term maneuvering.

China’s influence in Bangladesh has moved from commercial dominance to stra- tegic entrenchment. With bilat- eral trade reaching $24 billion in 2024 $22.88 billion of which was Chinese exports China has firmly established itself as Ban- gladesh’s top trading partner.

More tellingly, Beijing’s decision to roll over a $2 billion loan to Pa- kistan in March 2025, even as Is- lamabad grapples with the aftermath of a $7 billion IMF bailout, underscores China’s commitment to maintaining and deepening its regional alignments. Meanwhile, the inclusion of Afghanistan into the China-Pa- k i s t a n Economic C o r r i d o r (CPEC) as agreed in a May 2025 trilateral in Beijing represents a broader push toward a region- al infrastructure and influence matrix that could sideline India.

Symbolic gestures have rein- forced these trends: China’s announcement that a Pakistani astronaut will be the first foreigner to visit the Tiangong Space Station, and the inclusion of a Pakistani rover on the upcoming Chang’e 8 lunar mission, reflect a strengthening technological and strategic alliance.

Equally notable is the transfor- mation in Pakistan-Bangladesh relations. Decades of estrangement following the 1971 war have given way to fast-growing collaboration since August 2024. Bilateral trade between the two nations rose by 27% in just four months, and they now aim to hit a $3 billion trade target within a year The security dimension of this rapprochement is especially concerning.

Bangladesh’s participa- tion in the “Aman 2025” naval exercise hosted by Pakistan the first such collaboration in a decade marks a major shift. Between September and December 2024, Bangladesh procured large volumes of artillery and tank ammunition, along with 40 tonnes of RDX, from Pakistan.

Interest in acquiring Pakistani JF-17 fighter jets and potentially even Abdali missiles signals a deepening military engagement. Much of this realignment has occurred since the political tran- sition in Bangladesh following Prime Minister Sheikh Hasi- na’s departure in August 2024.

Under interim leader Muhammad Yunus, Dhaka has visibly distanced itself from New Delhi and moved closer to Beijing and Islamabad. Yunus choosing China as the destination for his first official foreign visit a break from South Asia’s tradition- al diplomatic etiquette was a strong message.

The invitation extended to Chinese stateowned companies to manage the long contested Teesta River project, despite India’s prior willingness to cooperate, further underscores this pivot The new axis was put to the test during the India-Pakistan standoff following the Pahalgam terrorist attack in May 2025, which killed 26 civilians.

In retaliation, India launched Operation Sindoor, targeting nine suspected terror sites in Paki stan-occupied Kashmir and Punjab. The crisis revealed the strategic recalibration underway. Instead of backing India, Bangladesh positioned itself as a “neutral” mediator. Yunus publicly commended both Indian Prime Minister Narendra Modi and Pakistani Prime Minister Shehbaz Sharif for agreeing to a ceasefire, departing sharply from Dhaka’s historic alignment with New Delhi during past regional crises.

The implications for India’s northeast are immediate and sobering. The revival of the Lal monirhat airbase, facilitated by Chinese and Pakistani collaboration, could effectively serve as a launchpad for operations close to the Siliguri Corridor. Given Pakistan’s past support for in surgent groups in the Northeast between 1991 and 2004, the specter of renewed covert destabili- zation efforts cannot be ignored.

India has responded with a mix of caution and defensive assertiveness. Enhanced troop deployment and surveillance around the Siliguri Corridor, along with the cancellation of key transshipment facilities for  Bangladeshi exports through Indian territory, signal a tight- ening of strategic controls.

Yet, the recent crisis also exposed the challenge of simultaneously managing multiple, intercon- nected flashpoints. The India-Pakistan confrontation in 2025 marked the first instance of Pakistani forces deploying advanced Chinese weaponry, including the HQ-9 air defense system, PL-15 air-toair missiles, and J-10 fighter jets.

This marks a new era in South Asian military dynamics, with China’s defense industry increasingly embedded in regional conflicts. The China-Pakistan-Bangla- desh axis is no longer a speculative alignment.

It has matured into an operational partnership with strategic coherence and ambition. What India once con- fronted as bilateral irritants has now coalesced into a trilateral framework that challenges its regional autonomy and security doctrine For India, this necessitates a rethink of its traditional bilat- eral engagement strategy.

The geopolitical reality demands a multi-pronged, region-wide ap- proach that combines diploma- cy, economic investment, military readiness, and strategic narrative-building. The northeastern states once hailed as India’s gateway to Southeast Asia now risk becoming its frontline in a new era of geostrategic competition. While the triangle may not yet be militarized to its full extent, the trajectory is clear.

The fundamental question is no longer whether this axis will test Indian resolve, but whether New Delhi can respond with the urgency and sophistication required to safeguard regional stability and its own strategic autonomy.

The time for reactive diplomacy has passed. India must now craft a comprehensive, forward looking regional strategy that anticipates challenges, preempts risks, and recalibrates alliances. Anything less would be a strategic miscalculation with long-term consequences.
