The decision was taken following several posts on social media highlighting the issue in the textbook titled 'Contemporary World Politics', which was published in 2007, and has not been revised since then, but only reprinted.
According to the NCERT (National Council of Educational Research and Training), the map was prepared by the University of Texas and comes with a disclaimer that the boundary representation is not necessarily authoritative.
"The Chapter 4, 'Alternative Centres of Power', focuses on the European Union, ASEAN and China. The map which figures on page 56 is not a map of India, but a map of East and South East Asia," it said.
"Later in this chapter, the topic under the heading 'India - China Relations' refers to competing territorial claims in Arunachal Pradesh and Aksai Chin.
"Aksai Chin is shown as an integral part of India in the map of India and its neighbours on page 149. However, the map on page 56 will be replaced with a map of Southeast Asia in the reprint edition," NCERT added in a statement.
