Background

Overview

Essential for understanding global trade, energy security, international law, and potential conflict zones. India's economic and strategic interests are directly linked to secure maritime routes and the principle of freedom of navigation.

Freedom of Navigation is a principle of customary international law and enshrined in the UN Convention on the Law of the Sea (UNCLOS), allowing vessels to transit through international waters without undue interference. Maritime choke points are narrow channels or passages connecting two larger bodies of water, strategically vital for global trade and energy security, making them potential flashpoints in international relations.
