China has built five airfields, a network of rail lines and more than 58,000 km of roads in the Tibet Autonomous Region (TAR), Lok Sabha was informed on Money.
In written answers, Defence Minister AK Antony said due to differences in perception of the Line of Actual Control (LAC), "situations have arisen on the ground that could have been avoided if we had a common perception of the LAC (with China)".
"The total road network in TAR is assessed to be 58,000 kms in the year 2010. Extension of Qinghai Tibet Railway to Xigaze is in progress. Another railway line from Kashgar to Hotan in Xinjinag Uighur Autonomous Region (XUAR) is also under construction.
"Five airfields in TAR have become operational and include Gongar, Linchi, Pangta, Hoping and Gar Gunsa," he said.
On the specific cases of infrastructure development by Chinese near the LAC, Antony said, "these are taken up with their authorities through the established mechanism of Hot lines, flag meetings and Border Personnel Meetings (BPMs)."
He said necessary steps have been initiated for ensuring that national security concerns are adequately addressed through development of infrastructure, including rail, roads and forward airfields as well as operational capabilities.
India has taken several steps including raising two Mountain Divisions of the Army in the northeast, deployment of four squadrons of its frontline Su-30 MKI fighters and is also considering deployment of Ultra Light Howitzers (ULHs) and light tanks in the territories along the LAC.
Several new and old air fields have been activated and new roads constructed to enable a quicker movement of troops and equipment in the region.
Antony said India's infrastructure development, force modernisation and restructuring is in consonance with its threat perception to secure borders and protect national interests.
