A review of high-resolution satellite imagery shows China constructing a new road along a part of the Tibet-India frontier along Arunachal Pradesh that India does not control. The area, however, falls within the McMahon Line, the historic boundary shown by the Survey of India on its official maps.
India and China have significant differences in perception over the coordinates of the boundary line in this area.
While India has never given up its claim to the region which was lost to China in 1959, sources said it presently lies "beyond the Line of Actual Control (LAC)". In other words, beyond the line that the Indian Army physically patrols and defends.
