The Old Silk Route or Silk Road which passes through East Sikkim is a part of the ancient network of trade routes which connected China to India. This route passed through Lhasa and Nathu La and Jelep La Pass and finally reached the port of Tamralipta (present Tamluk in West Bengal) from where it took to the sea and reached far east. This Ancient Silk Route is expected to have been discovered by traders as early as First Century AD.
