The Macartney-MacDonald line is described as follows: "From the Karakoram Pass the crests of the range run nearly east for about half a degree, and then turn south to a little below the 35th parallel.. Rounding... the source of the Karakash, the line of hills to be followed runs north-east to a point east of Kizil Jilga and from there, in a south-easterly direction, follows the Lak Tsung (Lokzhung) Range until that meets a spur.. which has hitherto been shown on our maps as the eastern boundary of Ladakh.[1]

The Macartney-MacDonald line was never accepted by China, although they informally indicated acceptance on certain occasions:

• Woodman, Dorothy (1969) Himalayan Frontiers: A Political Review of British, Chinese, Indian, and Russian Rivalries, Praeger, p. 102 "The proposed boundary seems never to have been considered in the same form again until Alastair Lamb revived it in 1964."
• Lamb, Alastair (1965). "Treaties, Maps and the Western Sector of the Sino-Indian Boundary Dispute". The Australian Year Book of International Law. "Unfortunately, the Chinese never replied formally to the note, though they indicated informally on a number of occasions their agreement as to its boundary alignment."

In 1959, Chou confirmed the new Chinese claim line to Nehru.
