Indian and Chinese militaries on Tuesday held an over 10-hour Corps Commander-level dialogue with a focus on finalising modalities for the disengagement of troops from various standoff points in eastern Ladakh, sources in government said. The Indian delegation conveyed concerns over China's "new claim lines" in the region and demanded restoration of status quo ante as well as immediate withdrawal of Chinese troops from Galwan Valley, Pangong Tso and a number of other areas, sources further said.
