evidence: The disputed Aksai Chin-Ladakh area [...] Another point of contention is the China National Highway 219 (G219) connecting Xinjiang to Tibet. Originally built in 1957 and made of gravel, G219 was upgraded to asphalt in 2013. About 179km of the highway passes through the disputed Aksai Chin plateau. [...] The Galwan River is the highest ridge line and overlooks the DSDBO road, posing a direct threat to the highway’s security. By controlling this area China can keep India’s claims on the Aksai Chin plateau in check. India claims China has recently begun amassing troops in the LAC and venturing deeper into the contested area.
