When the armies of India and China were locked in a standoff along the Line of Actual Control last summer, People's Liberation Army (PLA) was quick to install a fibre optic network in remote areas of that region. According to a report released by the Pentagon titled: 'Military and Security Developments Involving the People's Republic of China 2021', the PLA installed the fibre optic for increased protection from foreign interception as well as faster communication in the remote areas of that region.
Though the world was in a state of lock-down due to the coronavirus pandemic, the Chinese PLA in 2020 was more in a rush to deploy more troops and machines and this was going on even as the two sides were engaged in military and diplomatic dialogues.
