According to reports, three huge artificial lakes, whose size and volume of water in them are yet to be ascertained, were formed in the Brahmaputra river due to a landslide after a 6.4-magnitude earthquake in Tibet last month.
The massive accumulation of water has caused concerns that if the lakes join or burst, millions of people residing along the banks of the river in Arunachal Pradesh and Assam - both of which are downstream - could get affected.
"The Chinese side, through the existing channels, will maintain communication with the Indian side on the cross-border rivers," Chinese Foreign Ministry spokesperson Hua Chunying told media persons in Beijing.
She said verification by the Chinese authorities has revealed that the lakes are on the eastern section of the India-China boundary.
"It is caused by natural factors. It is not a man-made accident," she said, referring to reports of the lakes being detected by satellites.
She said the Chinese officials concerned will maintain communication with the Indian side on the issue.
Earlier, China had refuted reports that the highly-polluted water in the river was caused by attempts to build a massive tunnel to divert the water to neighbouring arid Xinjiang region.
The issue was reportedly discussed during the recent 20th border talks between National Security Adviser Ajit Doval and Chinese State Councillor, Yang Jiechi on December 22 in Delhi.
