You are using Google Earth, I am using foottracks Or dirt tracks. Read the link I just posted, it's written by the editor of the number one daily of our state.Your claims seems to be over exaggerated. Tawang is located only at a distance of about 16 km from the LAC (McMohan Line). By your account, then, it shall be under the occupation of Chinese, which obviously is not the case. In my opinion, Chinese have never crossed the McMohan Line, as delimited on the maps, except for a short period, during 1962 War, which they vacated after the unilateral ceasefire.
Also I didn't say the Chinese are building inside AP, but that they come in and mark the territory. Read the other newslink I provided previously, it says 35km and 50 km as the areas where Chinese patrols camped inside LAC. We have 1080 km border with China and most of it is 4000 metres asl and trackless
