Diphu Pass
Diphu Pass() is a mountain pass around the area of the disputed tri-point borders of India, China, and Myanmar. Diphu Pass is also a strategic approach to eastern Arunachal Pradesh in India. It lies on the McMahon Line. It is located in Anjaw district of Arunachal Pradesh, 120 km northeast of district headquarter at Hawai via Hawai-Walong-Dong-Kibithu-Kaho-Dhipu Pass route. Kaho on LAC is 40 km west of Dhipu Pass. Walong airstrip, 60 km away, is has the nearest air connectivity. In October 1960 China and Burma demarcated their border to the Diphu  Pass, which is 5 miles south of the watershed of the mountain ranges. However, this caused a diplomatic row with India, which expected the tri-point to be at the watershed. The dispute has become part of the ongoing border disagreement between China and India regarding Arunachal Pradesh.
