'''Diphu Pass''' is a [[mountain pass]] on the border between [[India]] and [[Myanmar]], close to their trijunction with [[China]]. The provinces on the two sides of the border are the [[Arunachal Pradesh]] state of India and the [[Kachin State]] of Myanmar. The Burma part of the 1914 [[McMahon Line]], which demarcated the border between [[British India]] and [[Tibet (1912–1951)|Tibet]], runs from Diphu Pass to the [[Isu Razi Pass]].<ref>{{cite book

==History==
In October 1960, China and Burma (now [[Myanmar]]) demarcated [[India–Myanmar border|their border]] to Diphu Pass, which is {{Convert|8|km|mile}} south of the [[Drainage divide|watershed]] of the mountain ranges. However, this caused a diplomatic row with India, which expected the tri-point to be at the watershed.<ref>{{cite book
