India-Bangladesh, India-Myanmar and India-Sri Lanka Boundaries
India-Bangladesh Border
- India’s 4,096 km long border with Bangladesh is the longest.
- This boundary has been determined under the Radcliffe Award, which divided the erstwhile province of Bengal into two parts.
India-Myanmar Boundary
- This boundary runs roughly along the watershed between the Brahmaputra and Ayeyarwady [Irrawaddy].
- It passes through thickly forested regions, with Mizo Hills, Manipur, and Nagaland on the Indian side and Chin Hills, Naga Hills, and Kachin State on the Myanmar side.
India-Sri Lanka Boundary
- India and Sri Lanka are separated by a narrow and shallow sea called the Palk Strait.
- Dhanushkodi on the Tamil Nadu coast in India is only 32 km away from Talaimanar in the Jaffna Peninsula in Sri Lanka. These two points are joined by a group of islets forming Adam’s Bridge.
- Though peace has largely prevailed concerning the Indo-Sri Lanka border, there were tensions over the ownership of Kachchatheevu Island in the Palk Strait. It was given by India to Sri Lanka in 1974.
