In October 1960 China and Burma demarcated their border to 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
Pangsau Pass or Pan Saung Pass, 3,727 feet (1,136 m) in altitude, lies on the crest of the Patkai Hills on the India-Burma (Myanmar) border. The pass offers one of the easiest routes into Burma from the Assam plains. It is named after the closest Burmese village, Pangsau, that lies 2 km beyond the pass to the east.
The second-largest gap in the Western Ghats which is situated five kilometers from town is known by its name that is Shencottah Gap road-rail lines pass through this gap which connects Shencottah with Punalur.
The ghat has a bit of historical evidence. The ghat was the ancient route developed by Satavahana to connect the ports of Choul, Revdanda Panvel, etc. on the Konkan coast and the surrounding areas on the Deccan plateau. Today the ghat plays a massive part of the Great Indian Peninsula Railway laid from Mumbai to Pune.
