About McMohan line

  • McMahon Line serves as de facto boundary between China and India in the Eastern Sector.
  • It specifically represents boundary between Arunachal Pradesh and Tibet, from Bhutan in the west to Myanmar in the east.
  • It extends from corner of Bhutan to Isu Razi Pass on the Burma border.
  • 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, and it is called the McMahon Line after his name.
  • 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.
