evidence: Table 3: Type of Incidents were aerial incidents. While three aerial incidents were reported in the Western Sector, no aerial incidents were found in the Eastern Sector. The highest number of aerial incidents occurred in the period 2012- 2014, and all three of them were in the Middle Sector, over the state of Himachal Pradesh. Chinese helicopters were reported to have entered Indian airspace near Kaurik and Lapcha areas in the tribal districts of Kinnaur and Lahaul Spiti on 16 March and 19 March. Nothing is known about the third incident except its mention by Indo-Tibetan Border Police Inspector General, M.S. Bhurji as reported by TH.21 [...] Despite the agreements reached in consecutive years, the 2014 face- off in Chumar indicates the vulnerability of the CBMs in the absence of a clear roadmap for resolution of the border question. In the period that followed the signing of the 2005 agreement, China, at least on a couple of occasions, contravened certain key articles in it. The former Chinese Ambassador to India, Sun Yuxi’s assertion in 2006 that the whole of Arunachal Pradesh is Chinese territory was one such instance.42 His comments were in conflict with Article VII of the 2005 Agreement on the Political Parameters and Guiding Principles for the Settlement of the India-China Boundary Question which agrees in principle, that interests of settled populations on both the sides would be kept in mind while finding a solution to the border conflict.43 [...] 42.
