McMohan Line

Why in news? Recently, US recognised McMahon Line as international boundary between China and Arunachal Pradesh.

About:

• The McMahon Line was drawn during the Simla Convention of 1914, officially described as the Convention Between Great Britain, China, and Tibet. The line was determined by Sir Henry McMahon, then Foreign Secretary in the Government of British India.
• The McMahon Line serves as the de facto boundary between China and India in the Eastern Sector. It specifically represents the boundary between Arunachal Pradesh and Tibet, from Bhutan in the west to Myanmar in the east.
• China has historically disputed the boundary and claims the state of Arunachal Pradesh as part of the Tibetan Autonomous Region (TAR).

Shimla Treaty

• According to the Shimla Treaty, the McMahon Line is the clear boundary line between India and China. On behalf of India, the British rulers considered Tawang of Arunachal Pradesh and the southern part of Tibet as part of India and which was also agreed by the Tibetans. Due to this, the Tawang region of Arunachal Pradesh became part of India.
