China on Monday said that the flood situation in Yarlung Tsangpo River has returned to normal, which had arisen due to the formation of an artificial lake created by a landslide and blocking its main steam in Tibet which posed a major threat to India's northeastern states.

China also said it will continue to share the flood data with India.

People living along the banks of Siang river in Arunachal Pradesh were moved to safer places after China informed India about the landslide, which occurred on October 17, blocking Yarlung Tsangpo river in Tibet leading to the formation of the artificial lake.

The Yarlung Tsangpo River is known as the Siang after it enters India at Arunachal Pradesh from the Tibetan region and is called the Brahmaputra once it reaches Assam.

Assam Chief Minister Sarbananda Sonowal on Saturday had also directed authorities in districts bordering Arunachal Pradesh to "remain alert" for possible flash flood and take all possible steps to prevent any major catastrophe.

"By October 20, the river section of the barrier lake has returned to normal. We will keep close monitoring of the landslide situation and maintain close communication and cooperation with the Indian side through the existing channels," Chinese Foreign Ministry spokesperson Hua Chunying told.
