New Delhi:In a significant development, India on Friday formally identified 27 locations and geographical features in Arunachal Pradesh on the official maps of the Survey of India, a move that comes amid repeated attempts by China to rename places in the border state. Why did India identify 27 locations in Arunachal? "Identifying them formally on the Survey of India map of Arunachal Pradesh is aimed at facilitating their accurate recognition and better awareness among the public at large," the Centre said in a statement. The other areas include Bisa village, a strategically important high altitude mountain passes in the region Dzo La, Riza La, Pukur La. Zangnan is the Chinese name for Arunachal Pradesh.
