"Following ISRO's request for international disaster relief support, China has provided India with satellite data on India's flood-hit regions to assist its flood relief efforts. Hope all gets well soon," Sun tweeted.
China's state-run daily Global Times reported that India on July 17 sought international support in accordance with the International Charter on Space and Major Disasters, a multilateral mechanism aimed at sharing clear space-based data for countries affected by natural or man-made disasters.
China, which signed on the charter in 2007, responded rapidly to India's request by sharing images of flood-stricken regions in India taken by Chinese satellites, the daily said.
The two countries have large potential for cooperation, in which China's possession of cutting-edge technologies can be instrumental for India's disaster relief, the report said.
Large parts of India's northeast and Bihar are grappling with a worsening flood situation.
