With the onset of monsoons, China has begun sharing hydrological data with India on the flow of Brahmaputra river for this year and is also expected to start sharing data on the Sutlej river from 1 June, reports Economic Times.

Originating in China's Tibet and flowing into India's Arunachal Pradesh and Assam, the Brahmaputra then flows into the Bangladesh before ultimately draining into the Bay of Bengal. Meanwhile, Sutlej, a tributary of the Indus river, also originates in China's Tibet and flows into India before entering Pakistan.

The data on the flow of these rivers holds significance for the Indian government as it is necessary for flood management in peak monsoon seasons when the rivers swell up in size because of the heavy rains.

It should be noted thought that China had stopped sharing the data on Brahmaputra river in 2017 following the Dokalam stand-off between the two South Asian giants. It had then claimed that the hydrological data gathering sites had washed away due to heavy flooding. It was later in 2018 with the strengthening relations that China resumed the sharing of data.

The data on Brahmaputra river is shared from 15 May while on Sutlej from 1 June and the sharing of data continues till 15 October every year. Last year, China provided the data even beyond the October deadline after the Brahmaputra had witnessed formation of a lake due to a landslide that had increased the water levels.
