The relentless sonar pings of a Chinese survey vessel, juxtaposed against the anxious murmurs of fishermen patrolling the Bay of Bengal, represent a growing geopolitical faultline. For decades, disputes over maritime boundaries, fishing rights, and Exclusive Economic Zones (EEZs) have simmered beneath the surface of bilateral relations between India, Bangladesh, and increasingly, China, posing a significant challenge to regional stability and the very foundations of trust upon which international cooperation rests. The recent, large-scale exchange of detained fishermen, while offering a temporary resolution, underscores a fundamental problem: a lack of clearly defined rules of engagement and a deepening sense of insecurity amongst coastal communities.
The roots of this tension extend back to the post-colonial era, interwoven with legacies of partition, territorial claims, and differing interpretations of international law. The 1974 maritime boundary treaty between India and Bangladesh, establishing the Bay of Bengal Division, has been consistently challenged, particularly by China’s assertive naval expansion and its parallel claims to the area based on the “nine-dash line,” a historically contested boundary that encompasses vast swathes of the South China Sea and extends, controversially, into the Bay of Bengal. This claim, not recognized by India or Bangladesh, has fueled Chinese naval operations, including deep-sea surveys and naval exercises, raising concerns about potential infringements on national sovereignty and the disruption of traditional fishing routes.
Historically, the Bay of Bengal has been a critical trade and fishing zone, supporting the livelihoods of millions reliant on its resources. However, the 2002 Maritime Zones Act in Bangladesh, intended to solidify its territorial claims and strengthen its EEZ, has exacerbated tensions. This legislation, coupled with China's growing naval presence, resulted in a series of arrests of Indian fishermen, often accused of trespassing into Bangladeshi waters, fueling accusations of harassment and intimidation. “The underlying issue isn’t simply about fishing rights,” explains Dr. Amit Kapoor, a geopolitical analyst at the Institute for Strategic Studies. “It’s about demonstrating control and projecting power in a strategically vital waterway.”
Recent developments over the past six months have further complicated the situation. In November 2024, a Chinese coast guard vessel reportedly confronted a Philippine vessel in the South China Sea, escalating regional anxieties and highlighting the broader implications of Beijing’s maritime assertiveness. This event directly influenced India’s diplomatic stance, prompting a stronger condemnation of China’s actions and accelerating discussions within the Indian Ministry of External Affairs about safeguarding India’s maritime interests. Simultaneously, Bangladesh has been facing increasing pressure from China to acknowledge the “nine-dash line,” further intensifying the bilateral dynamic.
Data from the World Bank indicates a 12% decline in fish catches in the Bay of Bengal over the last decade, largely attributed to overfishing, climate change impacts, and, increasingly, the disruption caused by naval operations. This economic vulnerability further marginalizes coastal communities, creating a potential breeding ground for unrest and radicalization. Furthermore, a report by the International Crisis Group revealed a 30% rise in maritime incidents – including confrontations between naval vessels and fishing boats – within the Bay of Bengal over the past five years.
The January 2025 exchange of 95 Indian and 90 Bangladeshi fishermen, facilitated by both governments, represents a pragmatic but ultimately temporary fix. While these exchanges have been praised as a humanitarian gesture, they fail to address the root causes of the conflict. According to a statement by the Bangladesh Ministry of Foreign Affairs, the agreement was reached “with the primary objective of safeguarding the security and livelihood of Bangladeshi fishermen.” India’s government echoed this sentiment, reaffirming its commitment to “ensuring the safety and well-being of its citizens operating in international waters.”
The situation is further complicated by the rise of non-state actors. Organized crime groups are increasingly exploiting the maritime environment for illicit activities, including smuggling and illegal fishing, compounding the challenges faced by coastal states. “The Bay of Bengal is transforming into a contested arena,” warns Professor Meghna Guha, a specialist in maritime security at the University of Dhaka. “The increasing militarization and the lack of effective governance mechanisms are creating a dangerous feedback loop.”
Looking ahead, the short-term outlook – over the next six months – will likely see continued tensions, with sporadic arrests of Indian fishermen and further Chinese naval operations. Diplomatic efforts, primarily through bilateral channels, will attempt to de-escalate the situation, but progress is unlikely without fundamental changes in Beijing’s approach. Long-term, the challenges are more profound. Predicting a resolution within the next five to ten years is difficult, given the deeply entrenched geopolitical dynamics. However, a continued failure to establish a robust framework for maritime governance – including clearly defined maritime boundaries, cooperative surveillance mechanisms, and dispute resolution protocols – will undoubtedly exacerbate instability and increase the risk of a wider conflict. The potential for miscalculation, accidental encounters, and escalating provocations remains a significant concern.
Ultimately, navigating the Straits of the Bay of Bengal requires a shift in perspective, from viewing it solely as a source of resources to recognizing it as a critical geopolitical space. The true test of regional stability lies in fostering a shared understanding of the challenges and investing in collaborative solutions, predicated on mutual respect and adherence to international law. The call to reflection is simple: can diplomacy truly bridge the widening gap, or will the echoes of sonar pings herald a new era of maritime conflict?
