Understanding Mountain Passes Near India-China-Myanmar Border

Mountain passes are crucial geographical features that provide routes through mountainous terrain, connecting different regions or countries. The question asks to identify the specific pass located at the point where the borders of three countries meet: India, China, and Myanmar. This point is often referred to as a tri-junction border.

Let's examine the given options to determine which pass is situated at this significant tri-junction:

• Khardung Pass: Khardung Pass is located in the Ladakh region of India. It is historically important but is within India, connecting the Indus valley with the Shyok and Nubra valleys. It is not near the tri-junction of India, China, and Myanmar.
• Bum Pass: While there are several passes with similar names in mountainous regions, none are widely recognized as being precisely at the tri-junction of India, China, and Myanmar. Specific passes like Bum La Pass are on the India-China border further west, not at the tri-junction with Myanmar.
• Diphu Pass: Diphu Pass is a mountain pass located at the tri-junction of India, China (specifically Tibet), and Myanmar. It is situated on the McMahon Line, which forms the de facto border between India and China in this region. This pass is an important traditional route.
• Tulung Pass: Information on a prominent pass named Tulung Pass specifically at the India-China-Myanmar tri-junction is not widely available in standard geographical texts related to this specific border area. Passes in the region might have local names, but Diphu Pass is the recognized one at the tri-junction.

Based on geographical knowledge, the Diphu Pass is the correct answer as it is specifically located at the tri-junction point where the borders of India, China, and Myanmar converge.

Therefore, the pass located at the tri-junction border of India, China, and Myanmar is Diphu Pass.
