Despite increased political and economic relationship between India and China, the report to the US Congress said, tensions remain along the Sino-India borders with rising instances of border violation and aggressive border patrolling by Chinese soldiers.
Noting that China continues to maintain its position on what its
territorial claim is, the official said
the two capitals- Beijing and New Delhi are having a fair negotiation to maintain relative stability in that border area.
In its annual report, the US Defence department said, to decrease violence, the PLA has replaced older liquid-fuelled, nuclear CCS-3 missiles with more advanced and survivable fuelled CSS-5 MRBMs.
"China is currently engaged in massive road and rail infrastructure development along the Sino-India border primarily to facilitate economic development in western China," improved roads also support PLA operations," the Pentagon said.
Inspite of fair negotiation between the two countries tensions remain along their shared 4,057 km border, mostly over Arunachal Pradesh, which China asserts as part of Tibet and over the Aksai Chin region at the western end of the Tibetan Plateau.
