Foreign Policy Watch: India-SAARC Nations

[17th June 2025] The Hindu Op-ed: India’s uneasy balancing act in the Bay of Bengal

PYQ Relevance:

[UPSC 2022] Do you think that BIMSTEC is a parallel organisation like the SAARC? What are the similarities and dissimilarities between the two? How are Indian foreign policy objectives realized by forming this new organisation?

Linkage: This article highlights India’s efforts to “reinvigorate BIMSTEC” and the significance of the BIMSTEC Maritime Transport Cooperation Agreement in reducing trade friction and fostering multimodal linkages within the Bay of Bengal, with a broader goal of positioning India as a “regional integrator”. This question directly examines India’s foreign policy objectives through such regional organizations, which are central to its balancing act in the Bay of Bengal.

 

Mentor’s Comment:  India’s decision to cancel Bangladesh’s transshipment facility — once seen as a step towards closer regional trade — has created tension in the Bay of Bengal region. This move came at a time when Bangladesh was seen to be strengthening ties with China, leading many to believe that India’s trade decisions are now being influenced by its strategic concerns. What was once neutral and shared trade infrastructure is now becoming politically sensitive. This is important because India is also trying to promote regional trade through BIMSTEC and position itself as a leader of fair, rules-based trade. But this action goes against those goals, making it a turning point for India’s regional diplomacy.

Today’s editorial discusses the implications of India’s recent decision to cancel Bangladesh’s transhipment facility. This content would help in GS Paper II (International Relations) in the mains Paper.

_

Let’s learn!

Why in the News?

India recently withdrew Bangladesh’s access to its ports for sending goods to other countries. This move has now created tension in the Bay of Bengal.

Why did India revoke Bangladesh’s transhipment facility?

  • Official Justification: Port Congestion: India cited logistical constraints and congestion at its ports, which were causing delays for Indian exporters, as the main reason for revoking the facility. Eg: Indian terminals at ports like Haldia and Kolkata were reportedly overloaded, affecting trade efficiency.
  • Perceived Political Message to Bangladesh: The move was seen in Dhaka as a political signal, possibly linked to Bangladesh’s growing ties with China and a speech by its interim Chief Adviser referring to India’s Northeast as “landlocked”. Eg: The announcement followed Bangladesh’s assertion that it was a maritime lifeline for India’s Northeast, which New Delhi viewed unfavourably.
  • Geopolitical Sensitivities and Strategic Hedging: India may have aimed to discourage strategic balancing by Bangladesh, especially as Dhaka has been reopening maritime trade with Pakistan and expanding engagement with Beijing. Eg: The timing suggested India was responding to Bangladesh’s diplomatic moves rather than acting purely on trade logistics.

What impact has this decision had on BIMSTEC trade and regional cooperation?

  • Undermines the Spirit of Cooperative Regionalism: The withdrawal of the transshipment facility has reintroduced political conditionality into what was seen as neutral trade infrastructure, weakening trust in regional integration efforts. Eg: BIMSTEC’s Maritime Transport Cooperation Agreement, aimed at easing trade, now appears less credible if access depends on bilateral politics.
  • Disrupts Bangladesh’s Export Logistics: Bangladeshi exporters, especially in ready-made garments (over 85% of its foreign earnings), now face higher costs and delays in routing shipments through alternatives like Sri Lanka or Southeast Asia. Eg: Exporters relying on Indian ports for faster global access must now divert shipments to costlier and less efficient routes.
  • Creates Regional Uncertainty and Strategic Caution: Other BIMSTEC members (like Nepal, Bhutan, Myanmar) may now view Indian trade infrastructure as subject to political shifts, potentially leading them to hedge against overdependence on India. Eg: If India’s trade facilitation appears transactional, smaller economies may seek Chinese or Southeast Asian alternatives, weakening BIMSTEC cohesion.

How does politicising trade affect India’s regional credibility?

  • Erodes Trust in India’s Leadership Role: When India uses trade access as a tool of political signalling, it undermines its image as a stable and reliable regional partner. Eg: Revoking the transshipment facility with Bangladesh due to geopolitical tensions contradicts India’s projected role as a neutral integrator under initiatives like BIMSTEC and Sagarmala.
  • Encourages Smaller Neighbours to Hedge Strategically: Politicised trade may push neighbouring countries to diversify economic dependencies and explore ties with rival powers such as China. Eg: Bangladesh’s increasing engagement with China, including maritime and economic cooperation, reflects a strategic shift partly influenced by India’s conditional economic approach.
  • Weakens India’s Push for Rules-Based Regional Order: If trade rules are seen as subject to India’s unilateral political decisions, it undermines the credibility of multilateral frameworks India champions. Eg: The credibility of a future BIMSTEC Free Trade Agreement could suffer if member states believe India might alter terms based on bilateral tensions.

Why is Bangladesh’s growing engagement with China a concern for India?

  • Strategic Encirclement through China’s Influence: Bangladesh’s closer ties with China raise fears of India being strategically encircled under China’s “String of Pearls” strategy, which aims to increase Chinese presence around India’s maritime periphery. Eg: China’s involvement in Bangladesh’s port infrastructure, like the Payra and Chattogram ports, gives Beijing a potential foothold in the Bay of Bengal, affecting India’s maritime security.
  • Dilution of India’s Role as a Regional Connector: If Bangladesh aligns more with China, it could sideline India’s efforts to be the primary economic and connectivity hub in South Asia. Eg: Bangladesh’s Chief Adviser referring to the country as the “maritime lifeline” for India’s Northeast indirectly challenges India’s Act East and Sagarmala initiatives.
  • Undermines BIMSTEC-Led Regional Integration: China is not a BIMSTEC member, and deeper Bangladesh-China economic ties may fragment the regional architecture that India is promoting through BIMSTEC. Eg: Bangladesh’s reopening of maritime trade with Pakistan and increased Chinese engagement may discourage rules-based, India-led cooperation in the Bay of Bengal.

What measures can India take to keep trade infrastructure geopolitically neutral? (Way forward)

  • Institutionalise Rules-Based Trade Frameworks: India should establish transparent, rules-based mechanisms for port access and transshipment to avoid ad-hoc or politically motivated decisions. Eg: Reinstating Bangladesh’s transshipment facility under a BIMSTEC Maritime Trade Protocol would ensure decisions are not influenced by political tensions.
  • Promote Multilateral Ownership of Regional Corridors: Trade corridors should be developed through collective BIMSTEC initiatives instead of bilateral control, reducing suspicion of Indian dominance. Eg: Projects like the India-Myanmar-Thailand Trilateral Highway can be expanded under a BIMSTEC umbrella for shared responsibility and access.
  • Separate Strategic Concerns from Economic Policy: India must draw a firm line between diplomatic disputes and regional trade policies to preserve trust and reliability. Eg: Avoiding retaliatory restrictions (such as land port bans on Bangladeshi goods) helps maintain India’s image as a credible regional partner, even during diplomatic disagreements.

Digital India Initiatives

Analysing Internet access and digital skills in India

Why in the News?

The National Sample Survey Office’s Comprehensive Annual Modular Survey (CAMS) 2022-23 is a landmark initiative that provides the first large-scale assessment of India’s digital landscape at the household and individual level.

What does the CAMS 2022–23 reveal about digital access and skills in India?

  • Broadband Access is Widespread but Unequal: 76.3% of Indian households have broadband internet, indicating strong national reach. Eg: In urban areas like Delhi, over 90% of households are connected, while in states like Arunachal Pradesh, only 60.2% have access.
  • Social and Economic Inequalities Persist: Broadband access is higher among General category households (84.1%), but much lower among SCs (69.1%)and STs (64.8%). Eg: In the lowest income decile, 71.6% of households lack broadband, compared to just 1.9% in the top decile.
  • High Mobile Ownership But Gender and Caste Gaps Remain: Over 94% of rural households own mobile phones, but usage is skewed. Eg: Only 25.3% of rural women in the General category use mobile phones independently, and the percentage is even lower among SC/ST women.
  • Basic Digital Skills are Still Limited: While many can use mobile phones, skills like emailing and online banking are still underdeveloped. Eg: Only 20% of rural and 40% of urban people can send or receive emails; only 37.8% of all people aged 15+ can perform online banking transactions.

Why does the digital divide still exist despite high internet penetration?

  • Economic Inequality Limits Access: While internet availability is high, affordability remains a barrier for poorer households. Eg: In the lowest income decile, 71.6% of households lack broadband, compared to only 1.9% in the top income group.
  • Social Disparities Affect Usage: Caste and gender-based inequalities reduce meaningful digital access and use. Eg: Among rural women from the General category, only 25.3% use mobile phones independently, with even lower figures among SC/ST women.
  • Low Functional Digital Literacy: Having internet access does not mean people have the skills to use it effectively for education or services. Eg: Only 20% of rural and 40% of urban populations can send or receive emails, showing a gap in practical digital usage.

What digital skills are lacking among rural and urban populations?

  • Email Communication Skills Are Low: A large section of the population cannot use basic email services. Eg: Only 20% in rural areas and 40% in urban areas can send or receive emails.
  • Spreadsheet and Arithmetic Skills Are Poor: Most people lack the ability to perform basic digital tasks like calculations in spreadsheets. Eg: Less than 40% of Indians aged 15+ can perform arithmetic operations in spreadsheets.
  • Online Banking Proficiency Is Limited: There is limited ability to use secure digital financial services. Eg: Only 37.8% of people aged 15+ in India can perform online banking transactions, indicating low digital financial literacy.

How can the government bridge the digital divide to meet the SDG 4 goals? (Way forward)

  • Subsidise Internet Access for Poor Households: Make broadband a basic utility, like water or electricity, to ensure universal access. Eg: Provide low-cost broadband plans or free connections for families in the bottom income deciles, where 71.6% lack connectivity.
  • Invest in Digital Skill Training: Launch nationwide programs to train youth and adults in essential digital skills. Eg: Government-backed digital literacy missions in rural areas can teach email use, spreadsheet functions, and online banking.
  • Promote Inclusive Technology Access for Women and Marginalised Groups: Ensure equal digital access for SCs, STs, OBCs, and women through targeted schemes. Eg: Initiate women-focused mobile usage schemes in rural areas, where only 25.3% of general category women use mobile phones exclusively.

Mains PYQ:

[UPSC 2021] Has digital illiteracy, particularly in rural areas, coupled with lack of Information and Communication Technology (ICT) accessibility hindered socio-economic development? Examine with justification.

Linkage: The article explicitly details the disparities in “broadband Internet facilities” and “mobile or telephone connections” between rural and urban areas, and across different states, caste groups (OBCs, SCs, STs, and General), and income deciles, directly addressing “ICT accessibility. This question directly aligns with the core themes presented in the article.

G20 : Economic Cooperation ahead

5 things to look out for in this year’s G7 Summit in Canada

Why in the News?

The 2025 G7 Summit in Alberta, Canada, is getting worldwide attention because Donald Trump has returned to the scene.

It’s happening at a time when global tensions are high, especially due to the rising conflict between Israel and Iran and the ongoing war in Ukraine.

What are the main issues discussed at the 2025 G7 Summit in Canada?

  • Escalating Iran–Israel Conflict and Nuclear Talks: Negotiations to curb Iran’s nuclear programme and manage fallout from Israel’s June 13 strikes dominated early sessions. Eg: G7 leaders debated sanctions and diplomatic channels to prevent wider Middle-East war.
  • Ongoing Russia–Ukraine War: Securing long-term military and financial aid for Ukraine remained central, with President Zelenskyy briefing leaders. Eg: Canada and Europe proposed a fresh aid package, while the U.S. stance under Trump stayed cautious.
  • Global Trade Frictions and Tariff Disputes: Rising U.S. tariffs on steel, aluminium and fentanyl-linked goods—and partners’ countermeasures—featured prominently. Eg: Canada pushed for a zero-tariff pact on steel and autos in bilateral talks with the U.S.
  • Climate Action, Wildfire Response and Critical Minerals: Leaders issued short joint statements on wildfires, decarbonisation and securing critical mineral supply chains for clean tech. Eg: Australia and Canada showcased joint plans to boost lithium and nickel output for EV batteries.

Why is Trump’s presence seen as influential at the summit?

  • Disruptive Diplomatic Style and Past Precedents: Trump’s unpredictable behaviour, seen at the 2018 Quebec G7, influences how leaders prepare for negotiations and outcomes. Eg: In 2018, he left early, refused to sign the joint communique, and insulted then-PM Justin Trudeau.
  • Tariff Impositions and Nationalist Policies: His administration’s new tariffs on G7 allies and aggressive trade policies create friction within the bloc. Eg: He imposed fentanyl-related tariffs on Canada and Mexico, accusing them of failing on illegal immigration control.
  • Polarising Political Rhetoric: His controversial remarks, such as suggesting Canada become the 51st U.S. state, fuel tensions and affect domestic politics in host nations. Eg: These comments weakened Conservative candidate Pierre Poilievre’s campaign and contributed to Mark Carney’s election win.

What is the impact of the Middle East and Russia-Ukraine conflicts on the G7 agenda?

  • Shift in Strategic Focus and Urgency: The escalating Iran-Israel tensions redirected attention from economic to security and defense cooperation among G7 nations. Eg: After Israel’s strike on Iran’s nuclear facilities, leaders emphasized the need to restrict Iran’s nuclear ambitionsand prevent wider conflict.
  • Unity and Division within the G7: The Russia-Ukraine war exposed divergent views, especially with Trump’s reluctance to support Ukraine, contrasting with NATO allies’ continued backing. Eg: Trump labelled Zelenskyy “ungrateful”, while Canada and Europe reaffirmed their military and diplomatic support to Ukraine.
  • Broader Global Message of Deterrence: The inclusion of both conflicts on the agenda highlighted the G7’s role as a global security actor committed to international law and sovereignty. Eg: Ukrainian President Zelenskyy’s invitation was intended to signal G7’s continued resolve against Russian aggression.

Why is India’s invitation to the G7 significant despite strained Canada-India ties?

  • Rebuilding Diplomatic Channels: The invitation marked a thaw in strained relations following the diplomatic row over the Hardeep Singh Nijjar killing allegations. Eg: Canadian PM Mark Carney personally invited PM Narendra Modi, indicating a willingness to resume dialoguedespite unresolved tensions.
  • Acknowledgment of India’s Global Role: India’s presence reflected its growing influence in global governance, especially on issues like climate change, trade, and geopolitics. Eg: Including India alongside other key non-member nations like Brazil and South Africa affirmed its importance to G7 strategic objectives.

Way forward: 

  • ​​Institutionalise High-Level Dialogue: Establish regular diplomatic and law enforcement exchanges between India and Canada to address mutual concerns and rebuild trust while keeping sensitive issues separate from broader strategic cooperation.
  • Strengthen Multilateral Collaboration: Leverage platforms like the G7, G20, and UN to deepen cooperation on global challenges such as climate change, critical minerals, and digital governance, showcasing shared interests beyond bilateral disputes.

Mains PYQ:

[UPSC 2023] What are the ways in which oil pollution affects the marine ecosystem? In what way is oil pollution particularly harmful for a country like India?

Linkage: Maritime Accident Response” explicitly talks about the “oil spills” as one of the three major peacetime maritime accidents that the Indian coast needs protection against. It also states that oil is a “more severe fire hazard” than hazardous cargo, especially in the context of gas-carrying merchant ships. This question directly addresses the environmental and national impact of oil pollution, which is a significant aspect of maritime accidents and firefighting efforts.

Climate Change Impact on India and World – International Reports, Key Observations, etc.

Ocean Darkening: A New Ecological Crisis

Why in the News?

A new study from the University of Plymouth has revealed that over 21% of the global ocean has significantly darkened in the last two decades.

What is Ocean Darkening?

  • Ocean darkening refers to the reduction in sunlight penetration into the ocean’s upper layers, known as the photic zone (up to 200 meters deep), where sunlight drives photosynthesis and supports marine biodiversity.
  • This process is measured using the diffuse attenuation coefficient (Kd 490), which tracks how quickly light diminishes as it passes through seawater.
  • The photic zone is essential for phytoplankton productivity, oxygen generation, marine food chains, and the regulation of global climate.

Recent Report Citing Ocean Darkening:

  • A new study by researchers from the University of Plymouth, published in 2024, titled “Darkening of the Global Ocean”, revealed that 21% of the global ocean has significantly darkened from 2003 to 2022.
  • Key findings:
    • 9% of the ocean saw a drop of more than 50 meters in light penetration—equal to the area of Africa.
    • 2.6% experienced a loss exceeding 100 meters in photic depth.
  • Affected Region: The study found the Arctic, Antarctic, Gulf Stream, and North Sea among the worst affected regions.
  • Causes:
    • Algal blooms from nutrient runoff in coastal areas.
    • Warming seas, altered plankton dynamics, and changing ocean currents in open ocean zones.

Implications of Ocean Darkening:

  • Ecosystem Disruption: Light-dependent species, such as Calanus copepods, are being pushed into shallower zones, increasing predation and competition.
  • Loss of Habitat: The shrinkage of the photic zone could be one of the largest marine habitat losses ever, affecting fish stocks and biodiversity.
  • Climate Feedback Loop: Reduced photosynthesis in oceans could weaken the ocean’s role in carbon sequestration and oxygen production, worsening climate change.
  • Threat to Global Fisheries: The contraction of productive zones affects fish populations, jeopardising fisheries and food security.
  • Scientific Concern: Researchers warn that this hidden crisis could fundamentally alter marine ecosystems if not urgently addressed.
[UPSC 2025] With reference to the planet Earth, consider the following statements:

I. Rain forests produce more oxygen than that produced by oceans. II. Marine phytoplankton and photosynthetic bacteria produce about 50% of the world’s oxygen. III. Well-oxygenated surface water contains several folds higher oxygen than that in atmospheric air.

Global Geological And Climatic Events

Green Arabia Hypothesis in Human Evolution Research

Why in the News?

A recent study confirms that Arabia wasn’t always a desert wall but occasionally a green bridge between continents.

About the Green Arabia Hypothesis:

  • Core Idea: It suggests that the Arabian Peninsula, now one of the driest places on Earth, experienced multiple humid phases over the past 8 million years, turning it into a green corridor for early migrations.
  • Challenge to Old Views: This theory challenges traditional models that excluded Arabia from early human dispersal routes in the ‘Out of Africa’ narrative.
  • Fossil Evidence: The discovery of fossils of crocodiles, hippos, and horses, dating up to 74,000 years ago, supports the claim that Arabia was once lush and habitable.

Key Discoveries and Methods:

  • Archaeological Sites: Over 10,000 ancient lakebeds and sites over 500,000 years old were found, confirming Arabia’s role as a migration bridge between Africa and Eurasia.
  • Speleothem Analysis: 22 speleothem samples (mineral deposits formed within caves) from seven Saudi caves indicated humid phases between 7.44 million and 60,000 years ago.
  • Dating Techniques: Scientists used uranium-thorium dating to accurately time wet periods, revealing patterns linked to monsoon shifts and glacial cycles.
  • Environmental Impact: These wet intervals, though brief, supported vegetation, biodiversity, and water bodies, enabling human and animal settlements.

Significance of the Study:

  • Biogeographic Role: Arabia is now viewed as a climate-sensitive migratory bridge, not a barrier, in human evolution and dispersal.
  • Climate Dependency: Human movement was influenced not just by geography, but by shifts in rainfall patterns and monsoonal activity.
  • Key Locations: Sites like Jubbah Oasis provided stone tools and lakebed evidence, validating early human habitation in the region.
  • Conclusion: Arabia’s periodic greening played a decisive role in early human migration, revising our understanding of ancient dispersal pathways out of Africa.
[UPSC 2014] Which of the following phenomena might have influenced the evolution of organisms?

1. Continental drift

2. Glacial cycles Select the correct answer using the code given below.

Options: (a) 1 only (b) 2 only (c) Both 1 and 2* (d) Neither 1 nor 2
