• Location: It is  an island in the Palk Strait, 14 nautical miles from Rameshwaram, and has for long been a bone of contention between India and Sri Lanka.
• Cause of contention: The close proximity of the island to both India and Sri Lanka has been the main cause of contention.
• Historical background: Records indicate that the island was once a part of the Ramnad Kingdom, but Ceylon (now Sri Lanka) also  claimed ownership  of it. Under British control, it was jointly run.                                    
• Current Status:  In 1974 and 1976 two agreements between the  nations were signed. Then Indian Prime Minister Indira Gandhi, and then Sri Lankan Prime Minister Sirimavo Bandaranaike signed agreements making Katchatheevu a part of Sri Lanka. Even since, with Katchatheevu determining the maritime border, fishing rights have been a topic of debate on both sides.
