What happened to the territorial dispute between China and India originating from McMahon Line?

During the period from 19 13 to 19 14, an Englishman named William Henry McMahon drew a line on the map and took away 90,000 square kilometers of land in China and Tibet, but this line has not been recognized by successive governments in China until now, and it is only a boundary unilaterally drawn by Britain. India wants to divide its borders according to the McMahon line, but China certainly doesn't agree, so there is a territorial dispute between the two countries.
