Storms have pummelled the region since the beginning of the month, with some monitoring stations reporting rainfall at historic levels, the Xinhua News Agency said.

Almost two million people have been affected in the largely rural, mountainous province - 286,000 of whom have been evacuated to safety while more than 2700 houses have been damaged or collapsed entirely, Xinhua said.

China regularly experiences flooding during the summer months, most frequently in central and southern areas that tend to receive the most rainfall.

China's worst floods in recent years were in 1998, when more than 2000 people died and almost three million homes were destroyed, mostly along the Yangtze, China's mightiest river.

The government has invested heavily in flood control and hydroelectric projects such as the gargantuan Three Gorges Dam on the Yangtze.

Globally, more intense tropical storms are on the rise as a result of climate change, leading to increased flooding that threatens human lives, crops and groundwater quality.
