In March 1899 the British proposed, in a formal Note from Sir Claude MacDonald to China, a new boundary between China and British India. The Note proposed that China should relinquish its claims to suzerainty over Hunza, and in return Hunza should relinquish its claims to most of the Taghdumbash and Raskam districts. The Note proposed a border which broadly followed the main Karakoram crest dividing the watersheds of the Indus River and the Tarim River, but with a variation to pass through a Hunza post at Darwaza near the Shimshal Pass. The Chinese did not respond to the Note and the Indian government never revisited the boundary in the same form again. The MacDonald line was modified in 1905 to include in India a small area east of the Shimshal Pass, to put the border on a stretch of the Shaksgam River.
