Heavy rain in China has claimed six lives this week and forced the evacuation of some 200,000 people.

Five people died in southeastern China, according to state media reports: A house collapse took three lives in Fujian province on Tuesday, and two died on Monday in a landslide caused by torrential rain in neighbouring Jiangxi province.

One person died and three are missing in northern China after a vehicle fell into the water in mountain flooding from heavy rain in the Inner Mongolia region.

The mainland regularly experiences seasonal rains and flooding during the summer, most frequently in central and southern areas.

Video on CCTV showed large parts of cities flooded in muddy waters. Rescue workers carried trapped people out of buildings on their backs in waist-deep water in Guangdong province.

The rain ended on Wednesday in Jiangxi, but more precipitation is forecast for another week in Fujian, Jiangxi and Guangdong and the nearby Guangxi region. The National Meteorological Centre said residents should prepare for floods and landslides as the soil is already saturated in those areas.

More than 110,000 people have been relocated in Jiangxi province, along with more than 80,000 in Fujian, state media reports said. (AP)
