Sir Creek Dispute: The Marshy Southern Tip of the Pakistan–India Border
At the very start of the 3,323 km frontier — where it meets the Arabian Sea — lies Sir Creek: a tidal marsh both countries claim, un-demarcated for 79 years. This guide explains the dispute, what’s at stake, and why it still matters.
Quick answer: Sir Creek is a ~96 km tidal estuary between Sindh (Pakistan) and Gujarat (India) whose boundary was never demarcated. Pakistan claims the creek’s eastern bank (a 1914 British resolution); India claims the mid-channel. The dispute also blocks agreement on the maritime boundary and its fishing and energy resources.
The creek
Sir Creek is a winding tidal estuary, about 96 km long, in the marshes between Sindh and Gujarat — part of the greater Indus delta wetlands. The Radcliffe award defined the boundary “from the mouth of Sir Creek to the top of Sir Creek, and from the top of Sir Creek eastward” — but the creek itself, shifting with tides and silt, was never surveyed. The 1968 Tribunal Award fixed the boundary eastward from the creek’s top, but left the creek’s own line open.
The two claims
- Pakistan: cites a 1914 resolution between the British government of Sindh and the Rao of Kutch, placing the boundary on the creek’s eastern bank — making the whole creek Pakistani.
- India: argues the boundary should follow the mid-channel (the thalweg principle used in international law for navigable waterways).
What’s at stake
More than a marsh: the creek’s line determines the maritime boundary — and with it, exclusive economic zone rights over a slice of the Arabian Sea with fishing grounds and potential oil and gas reserves. Fishermen from both sides are regularly arrested for crossing the unmarked line; Sir Creek is where the border dispute most directly touches ordinary lives.
The talks record
Sir Creek has been on the bilateral composite dialogue agenda since the 1990s; technical-level talks mapped most of the area, and a settlement was reportedly close in 2012 — but the political moment passed. It remains the most “solvable” of the disputes: no populations to move, no heights to hold — just a line in a marsh. The frontier it anchors: border map.
