China on Thursday asked India to make preparations for "disaster prevention" amid widespread concern over the artificial dam in Tibet bursting and triggering flash floods in Himachal Pradesh.

"We have conveyed information collected to the Indian side in time and have reminded them to make preparations for disaster prevention," said Chinese embassy spokesperson Yang Shuying.

"We will continue to brief the Indian side on the latest development in a timely manner," she added.     

She said a landslide has blocked Pareechu River in the Tibet autonomous region since July.

Attaching great importance to the issue, the departments concerned on the Chinese side have been working day and night, monitoring closely the development of the situation and studying measures to cope with it, she said. 

Asked about the reason for delay in Beijing's clearance for a four-member Indian technical team to inspect the landslide area and the artificial dam and lake, Yang said, "It is a very difficult situation because of bad weather, landslide..." 

She said, "It is impossible for any person to enter that area."
