Security Nexus perspective, “Where Maps Blur and Rivers Speak: China, India, and the Contest for the Eastern Himalayas,” by Shyam Tekwani, explores a rising flashpoint in South Asia where geopolitics, geography, and water security converge. As India suspends the Indus Waters Treaty with Pakistan, this piece shifts focus eastward to the tri-junction of India, China, and Bhutan—a region marked by contested borders, spiritual significance, and increasingly fragile stability. Tekwani highlights the strategic importance of Arunachal Pradesh, where infrastructure build-up, unresolved territorial claims, and water disputes heighten the risk of conflict without warning or reliable de-escalation mechanisms.
