Downpours heavier than usual have battered parts of China in extreme weather since July, with the East Asian monsoon rains stalling over its north and south.

Three bodies were retrieved from flood waters in the Inner Mongolia city of Ordos, the official news agency Xinhua said, while three people were reported missing about 70km away near the banks of the Yellow River.

Yesterday’s downpour was the first of three forecast for the next few days, television news said.

It dumped more than 204mm of rain in less than 24 hours on the district where the bodies were found, or more than double the monthly average for August, weather authorities said.

On Saturday, a flash flood after a river burst its banks in the region’s grasslands killed at least 10 people, sweeping away 13 campers on the outskirts of the city of Bayannur, about 350km northwest of Ordos.

One of those was rescued, but two are missing.

Rescue workers are scouring for the three missing people in Ordos, in an area that is also close to one of China’s rare earth hubs, the city of Baotou.

Heavy rainfall and severe floods that meteorologists link to climate change pose major challenges for authorities, threatening to overwhelm ageing flood defences, displace millions and lead to economic losses running into billions.
