Context: India’s Defence Minister recently cautioned Pakistan against military activities near Sir Creek and referred to Operation Sindoor, highlighting India’s preparedness to secure its maritime boundaries.
About Sir Creek
- Geography: Sir Creek is a 96 km long tidal estuary located in the Rann of Kutch, separating Pakistan’s Sindh province and Gujarat’s Kutch region.
- History: Originally called Ban Ganga, it was renamed Sir Creek after a British surveyor during colonial mapping.
- Strategic Importance:
- Rich fishing grounds and potential oil & gas reserves.
- Decides maritime boundary, influencing the Exclusive Economic Zone (EEZ).
- Proximity to Karachi port makes it critical for naval security.

The Dispute
- The dispute stems from colonial-era demarcation between Kutch (India) and Sindh (Pakistan) under the Bombay Presidency.
India’s Claim:
- Boundary should follow the mid-channel (Thalweg Principle).
- Seeks resolution only through bilateral talks under the 1972 Simla Agreement.
Pakistan’s Claim:
- Boundary lies along the eastern bank (Green Line) as per the 1914 Bombay Government Resolution, giving Pakistan control of the creek.
- Argues Thalweg Principle doesn’t apply since Sir Creek is not navigable.
Key Concepts
- Thalweg Principle: In international law, boundaries in a navigable water body should follow its deepest channel, ensuring equal access.
- Simla Agreement (1972): Peace treaty post-1971 India-Pakistan War; stresses bilateralism, mutual respect, and LoC recognition.
Significance for India
- Ensures sovereignty over maritime resources and security in the Arabian Sea.
- Prevents encroachment into India’s EEZ, vital for energy and fisheries.
- Safeguards national security against Pakistan’s naval activities.
Way Forward
A negotiated settlement, balancing international law and bilateral agreements, is essential to prevent conflict and promote stability in the Arabian Sea region.
