July 19, 2026

TOPIC CLASSIFICATION

Subject: International Relations — Geopolitics — Maritime Security
Sub-topic: Indian Ocean Region (IOR) — Geostrategic Importance (Sea Lanes of Communication — SLOCs, Energy Routes, Chokepoints), Indian Ocean Rim Association (IORA — 1997), Major Players (India, China — String of Pearls, US — Diego Garcia, UK — BIOT, France — Réunion), Chokepoints (Strait of Malacca, Hormuz, Bab-el-Mandeb, Six Degree Channel, Sunda Strait, Lombok Strait), China's Presence in IOR (PLA Navy — Blue Water Navy, Djibouti Base, Gwadar Port, Hambantota, Sittwe, Ream Base — Cambodia), India's Maritime Strategy (SAGAR — Security and Growth for All in the Region, Indian Navy's Role, INDIAN OCEAN as 'Area of Peace', Andaman & Nicobar Command, INS Viraat — decommissioned), Maritime Security Threats (Piracy — Somalia, Sea lanes security, Drug trafficking, Illegal Fishing, Climate Change — Rising Sea Levels, Cyclones), Quad and Indo-Pacific (Maritime Domain Awareness — IPMDA), Indian Ocean Commission (IOC), Blue Economy, Sri Lanka, Maldives, Seychelles, Mauritius — India's Maritime Neighbourhood

EXAMINER REASONING

The Indian Ocean is central to India's security and prosperity — 90% of India's trade by volume and 80% of oil imports transit these waters. Prelims tests: IORA (HQ — Mauritius, 23 members), SAGAR, chokepoints (Malacca, Hormuz, Bab-el-Mandeb, Six Degree Channel, Sunda, Lombok), China's String of Pearls (Gwadar, Hambantota, Djibouti, Sittwe, Ream, Chittagong), IPMDA (Quad initiative), Diego Garcia (UK-US base), Andaman & Nicobar Command (India's first tri-service command), Exclusive Economic Zone (EEZ) of 2.4M sq km. Mains demands: (a) strategic importance — IOR carries 80% of global oil trade — India's SLOCs pass through these waters — energy security, trade security, and naval security converge here, (b) China's IOR strategy — 'String of Pearls' — ports and infrastructure around IOR — PLA Navy's blue-water ambitions — Chinese naval presence in Indian Ocean increasing (anti-piracy patrols — 14 consecutive years) — naval diplomacy, (c) India's response — SAGAR vision (2015) — Act East and Neighbourhood First through maritime lens — Indian Navy as net security provider in IOR — HADR operations (cyclones, Tsunami 2004, MH370 search) — building naval infrastructure (INS Kadamba at Karwar — Phase II — nuclear submarine base), (d) maritime domain awareness — India set up Information Fusion Centre (IFC-IOR) at Gurugram (2018) — shares shipping data with 20+ partner countries — IPMDA (Quad) provides satellite-based maritime surveillance to Southeast Asia/Pacific/Indian Ocean, (e) small island states — India's maritime neighbours (Sri Lanka, Maldives, Mauritius, Seychelles) — China's growing influence through BRI, infrastructure projects, debt-trap diplomacy — India's counter through development assistance, defence cooperation, vaccination diplomacy, (f) — any disruption at Hormuz (Iran) or Malacca (Malaysia-Singapore) would cripple Indian economy — need for alternative routes, strategic reserves. The examiner's favourite framing is: ""

Statement Elimination Guide

StatementTruth ValueWhy?
"India is the largest country in the Indian Ocean Region by population and GDP"TrueIndia accounts for 80% of IOR's population and over 60% of IOR's GDP — making it the natural leader
"China's String of Pearls refers solely to military bases"FalseString of Pearls refers to ports and infrastructure — only Djibouti is a confirmed military base — others are commercial ports with potential dual-use
"The Quad's IPMDA shares satellite-based maritime surveillance data"TrueIPMDA (Indo-Pacific Partnership for Maritime Domain Awareness) — uses existing satellite data — shared with partners (Pacific, Southeast Asia, Indian Ocean) — operational since 2023
"The Strait of Hormuz is the only chokepoint for India's oil imports"FalseIndia's oil comes through both Hormuz (Persian Gulf) and Malacca (SE Asia) — India diversifies through strategic petroleum reserves and alternative routes (Russia via Arctic)
"India has a military base in Seychelles"FalseIndia has built a naval dockyard (Assumption Island) but it remains under Seychelles control — India's military presence in IOR is through Karwar, A&N Islands, and joint access agreements

Current Affairs Hook

2023-26: Houthi attacks in Red Sea/Gulf of Aden (November 2023-2024) — Houthis targeting Israel-linked shipping in solidarity with Gaza — India's response: Indian Navy deployed destroyers (INS Kolkata, INS Chennai) for escort operations — no Indian commercial vessels attacked — demonstrated Indian Navy's role as net security provider. Maldives-India relations — President Muizzu's 'India Out' campaign (2023-24) — demanded Indian military personnel withdrawal — India replaced with civilian technical teams (2024) — China-Maldives FTA signed — delicate balancing for India. IPMDA expansion — Quad IPMDA extended to Pacific Island countries (2024) — satellite data for fisheries monitoring, climate resilience, maritime security. Andaman & Nicobar development — Great Nicobar Island mega-project approved — ₹10,000 Cr integrated development — deep-sea port, airport, transshipment terminal — strategic for Malacca strait monitoring. Sri Lanka crisis — China's Hambantota debt trap (99-year lease) — India's $4B assistance during Sri Lanka's economic crisis (2022) — India's counter through development partnership — tourism revival. INS Tushil (2025) — Russia-built Talwar-class frigate commissioned — Indian Navy's 46-ship construction programme (Sanjay, 17A, 15B, Kalvari). Chagos Islands deal (2024) — UK agreed to transfer sovereignty of Chagos Archipelago to Mauritius — retains Diego Garcia base for 99 years — India supported Mauritius's claim.


Interlinkages

  • → Maritime Security (GS-III): Piracy, SLOC protection, naval modernisation — Indian Navy's role
  • → Energy Security (GS-III): Oil and gas routes — Strait of Hormuz — strategic petroleum reserves
  • → Climate Change (GS-III): Sea level rise — IOR island states (Maldives, Seychelles — 1m above sea level) — cyclones
  • → Blue Economy (GS-III): Fisheries — deep-sea minerals — renewable energy (offshore wind, tidal)
  • → Small Island States (GS-II): India's maritime neighbours — development assistance — security cooperation
  • → China's Strategy (GS-II): String of Pearls — naval competition — India-China rivalry in IOR
  • → Defence (GS-III): Naval modernisation — INS Kadamba — A&N Command — nuclear submarines
  • → Trade (GS-III): SLOC security — global trade — Indo-Pacific economic corridor

Common Mistakes

MistakeCorrection
"The Indian Ocean is India's ocean"The IOR is not under Indian control — it's a global commons — India is the leading power but must share with US, China, UK, France, and others
"China has formal military bases all around the Indian Ocean"Only Djibouti (2017) is a confirmed PLA military base — other 'pearls' (Hambantota, Gwadar, Sittwe) are commercial ports with potential dual-use capability
"SAGAR is a military doctrine"SAGAR (Security and Growth for All in the Region) is a comprehensive maritime vision — includes security, development, connectivity, environment, and humanitarian assistance
"The Maldives is fully aligned with India's security interests"Maldives has pursued an 'India First' but not 'India Only' policy — 'India Out' campaign (2023-24) showed Maldivian nationalism can push against India — China has made inroads
"India's navy is the most powerful in the Indian Ocean"The US Navy (CENTCOM/INDOPACOM) remains the most powerful naval force in the IOR — Indian Navy is the most capable local power — growing modernisation gap with China's PLAN
