Seasoned diplomat Vikram Misri, widely regarded as an expert on China and national security, assumed charge as India's new foreign secretary on Monday. Misri, a 1989-batch Indian Foreign Service officer who was serving as the deputy national security advisor, succeeded Vinay Kwatra. He assumed charge of the key position at a time India is looking to navigate various geo-political challenges, including its frosty ties with China following the lingering eastern Ladakh border row and the consequences of the Russia-Ukraine conflict.
