📘 IAS Prelims 2025 — GS-I Q.62 | Classroom Explanation

(Transport Geography | International Corridors)

📌 Question Recap

India is one of the founding members of the International North–South Transport Corridor (INSTC), a multimodal transportation corridor, which will connect:

(a) India to Central Asia to Europe via Iran
(b) India to Central Asia via China
(c) India to South-East Asia through Bangladesh and Myanmar
(d) India to Europe through Azerbaijan

✅ Correct Answer: (a) India to Central Asia to Europe via Iran

🧑‍🏫 Classroom Explanation (Concept + Geography Mapping)

🔹 What is INSTC?

The International North–South Transport Corridor (INSTC) is a multimodal corridor (sea + rail + road) aimed at reducing time and cost of freight movement between:

👉 India → Iran → Central Asia → Russia → Europe

It was formally launched through an Inter-Governmental Agreement in 2000 by India, Iran, and Russia.

🗺️ Core Geographic Logic (Why Option A is Correct)

🔑 Central Spine of INSTC

• Starting Point: Indian ports (Mumbai / Mundra)
• Sea leg: To Iranian ports (Bandar Abbas / Chabahar)
• Land leg:
  • Through Iran
  • Into Central Asia (Turkmenistan, Uzbekistan, Kazakhstan)
  • Further north to Russia
  • Finally into Northern & Western Europe

👉 This exactly matches Option (a).

❌ Why Other Options Are Incorrect

❌ (b) India to Central Asia via China

• INSTC does not pass through China
• India–China connectivity is geopolitically constrained
• This route belongs more to BRI, not INSTC

❌ (c) India to South-East Asia through Bangladesh and Myanmar

• This describes Act East Policy projects
  (e.g., Kaladan Multimodal Project, India-Myanmar-Thailand Trilateral Highway)
• Not related to INSTC

❌ (d) India to Europe through Azerbaijan

• Azerbaijan is a participant, but:
  • It is one transit country, not the defining corridor logic
  • The corridor is India → Iran → Central Asia → Russia → Europe
• UPSC frames answers by core geographic intent, not a single node

👉 Azerbaijan is a link, not the conceptual description
