The Southwest Silk Road Route
The Southwest Silk Road route brought the Silk Road down into India and modern day Bangladesh, through the Ganges and Brahmaputra Delta, connecting India with China through trade, but goods from the West came to India via the Silk Road networks.
The logistics of this particular route is unclear, some academics believed it came through China over into Tibet, Nepal and then down into India. Others believe that the route went through Sichuan to Yunnan to Burma and then Bangladesh, where this route is known as the “Ledo” route, and has archaeological evidence to back up the claim.
Another way the Silk Road made it into India was also from the splinters of the Northern or even the Southern Route, coming down through Pakistan and Afghanistan into India via modern day Kashmir.
