It was bounded on the north by the mountain ranges that divide present-day Myanmar and Assam State, in the south by Khambat, reaching to Yunnan in the east and the Chin Hills in the west.

[3] According to ancient tradition the state of Pong has its origin in the legendary kingdom of Udiri Pale, founded in 58 BC.

The Manipuri chronicle of the region, titled the Cheitharol Kumbaba, written much later, mentions an alliance between the Kangleipak State and the Kingdom of Pong.

It also mentions that the King of Pong visited Imphal in 698 AD and resided for some time in the town.

Chukapha, one of those who had been prevented from becoming the ruler of Pong, left the country and found refuge in the Patkoi Hills, entering Assam through the Namrup river, a tributary of the Burhi Dihing.
