I have got an interesting article on PLA new activities in Tibet... Whats our Chinese friends will tell on this..
INCREASING MILITARY ACTIVITIES
Meanwhile, Chinese military activities in the region have expanded. In July 2010, the official newspaper of the PLA, People’s Liberation Army Daily, reported that units of the People’s Liberation Army Air Force (PLAAF) were engaging in armed combat air patrols. These are believed to have been advanced Su-27 or J-11 (domestically produced versions of the Su-27) fighter aircraft.
The combat air patrols were followed by an August 2010 logistics exercise involving the newly constructed Qinghai-Tibet railway. This exercise marked the first PLAAF use of the railway for military purposes, with the Military Transportation Department of the PLAAF Logistics Department overseeing the movement of “combat readiness materials” to Tibet. This would seem to reflect a growing PLAAF role in maintaining security along the Sino-Indian border in the Tibetan area.
In October 2010, there were reports that the PLA had conducted joint (inter-services) live-fire exercises in Tibet for the first time. These reportedly involved armour, artillery, air, and electronic warfare units and a variety of new equipment. Given the emphasis placed on joint operations in PLA doctrine, such exercises are not surprising, but instead reflect the extent to which they are being applied across the military, not just opposite Taiwan.
Indian expert observers do not interpret China’s new-found assertiveness as preparation for imminent conflict, and they continue to calculate that the overall probability of another Sino-Indian war is low. However, they believe China may be trying to enhance its bargaining position in the ongoing border negotiations. The Indian observers note that incursions across the disputed borders are likely aimed at gaining tactical advantage to bolster Chinese territorial claims.
India has somewhat belatedly sought to match the Chinese moves and to reinforce its own claims in the disputed border areas by augmenting forces and constructing roads along the shared frontiers. These measures include the deployment of two squadrons of Su-30 MKI fighter jets in Assam and the raising of two mountain divisions for deployment in Arunachal Pradesh. India also has redeployed elements of its 27th Mountain Division from Jammu and Kashmir to the patch of land that intersects India, Tibet, and Bhutan and links India with the rest of its northeastern states.
India is reviving air fields along the border with China, including one in the Ladakh region.
India must increasingly factor the potential threat of conflict over its disputed borders with China into its security planning and projections. While Indian strategists assess that Pakistan poses the most immediate threat to India, they increasingly view China as the more important long-term strategic threat.
In order to deter Chinese aggression along India’s border, Indian strategists believe they must develop the capability to inflict severe damage on Chinese forces in Tibet. China has an edge over India with regard to overall air power. Given infrastructure constraints in Tibet, however, China’s ability to deploy significant air power on the border with India remains in question.
