The Chicken's Neck is a vital part of India's internal security and geography because it connects the country's mainland with Northeast India. This location is strategically exposed because Bangladesh, Bhutan, Nepal, and China surround the region. The bottleneck created by the corridor's reliance on limited infrastructure could have serious implications for communication and transportation, as it is only about 20 to 25 kilometers wide at its narrowest point. The corridor serves as an important economic and security gateway, as it is crucial for troop deployment and supports India's Act East Policy. In addition, its vulnerability is further increased by environmental risks and multi-domain threats, including cyber activities. Moreover, the risk is heightened by the reliance on a limited number of supply routes. India is strengthening its infrastructure and maintaining cordial relationships with neighboring countries in order to improve security. The proposed subterranean railway is a major project aimed at protecting essential connectivity from potential threats.
