Ambiguity

The geographical extent is not clear cut as systemic and foreign policy orientations of its constituents are quite asymmetrical. Beyond the core territories of the Indian Empire (territories of the British Empire which were under the system of British Raj), there is a high degree of variation as to which other countries are included in South Asia. There is no clear boundary – geographical, geopolitical, socio-cultural, economical, or historical – between South Asia and other parts of Asia, especially Southeast Asia and West Asia.

The common definition of South Asia is largely inherited from the administrative boundaries of the Indian Empire, with several exceptions. The current territories of Bangladesh, India, and Pakistan which were the core territories of the British Empire from 1857 to 1947 also form the core territories of South Asia. The mountain countries of Nepal and Bhutan, two independent countries that were not under the British Raj but were protectorates of the Empire, and the island countries of Sri Lanka and the Maldives are generally included. By various definitions based on substantially different reasons, the British Indian Ocean Territory and the Tibet Autonomous Region may be included as well. Myanmar (Burma), a former British colony and now largely considered a part of Southeast Asia, is also sometimes included. Afghanistan is also included by some sources.
