NEW DELHI – Amid a protracted standoff with India at the border in Sikkim, China’s army has conducted new drills in Tibet that included targeting ‘enemy’ aircraft and tanks, NDTV reported on Monday.

The report, however, did not specify when and why the 11-hour exercise was held. The exercises were reported by state-run China Central Television (CCTV).

A video posted online showed soldiers using anti-tank grenades and missiles against bunkers and howitzers for artillery coverage. The video also showed radar units identifying enemy aircraft and soldiers using anti-aircraft artillery to destroy targets.

Earlier reports said the Chinese army recently tested a new light battle tank being manufactured by China.

According to Hindustan Times, the report is being seen as a message to the Indian government and military, as China claims large parts of Arunachal, India’s easternmost state, as southern Tibet.
