India has increased its claim in the Central Arabian Sea, as part of its ‘extended continental shelf’ by nearly 10,000 square km.
It also modified an earlier claim to avoid a long-standing dispute with Pakistan over the maritime boundary between the two countries.
Coastal countries have an ‘exclusive economic zone,” (EEZ) which gives exclusive mining and fishing rights, up to 200 nautical miles from their coastlines.
In addition to this, such states can also make claims for more area in the ocean provided they can scientifically establish to a UN body, called the Commission on the Limits of the Continental Shelf (CLCS).
For this, the claimed area extends unbroken from their landmass all the way till the sea bed.
India already has 12 nautical miles of territorial sea and 200 nautical miles of the EEZ measured from the baselines.
India made its first claim in 2009 in vast stretches of sea spanning the Bay of Bengal, Indian Ocean and the Arabian Sea.
Some parts of India’s continental shelf claims in the Arabian Sea overlap with that of Oman.
However, the two countries have an agreement in place since 2010 that while the continental shelf between them is yet to be delimited, it is ‘not under dispute.’
But there is a dispute with Pakistan over the Sir Creek, a strip of water in the marshes of the Rann of Kutch in Gujarat.
