Siliguri corridor is a place in India that connects the Northeast region with the rest of India. Think of it like a narrow pathway that connects two big houses. This pathway is only 22 kilometers wide at its narrowest point and is surrounded by mountains on either side.
The Northeast region of India is made up of seven states and is geographically separated from the rest of India by Bhutan, China, Myanmar, and Bangladesh. The Siliguri corridor is the only land connection between these two parts of India.
Lots of important things pass through this corridor, like people, goods, and supplies. It's like a very busy road that connects two important places. This corridor is very important because if it gets blocked or attacked, then it would be very difficult for people and supplies to reach the Northeast region.
In simpler terms, the Siliguri corridor is a very important place because it connects two big parts of India, and if it gets blocked, it would be difficult to go from one place to the other.
